Parts will include items such as:

* Front diffusers / splitters
* Rear diffusers
* Fender/guard components
* Aero components
* Other exterior automotive parts

### What we need

We need someone who can take our existing 3D scan data and turn it into **clean, accurate, manufacturing-ready CAD geometry** that can be supplied to our manufacturer for mould/tooling and composite/carbon-fibre part production.

This is **not simply an STL-to-STEP file conversion job**.

The successful freelancer should understand the complete workflow from:

**3D scan / mesh → reverse engineering → CAD reconstruction → validated production-ready file**

Depending on the scan and component, the work may include:

* Inspecting and cleaning scan/mesh data
* Repairing scan imperfections where necessary
* Reconstructing surfaces and geometry
* Creating clean CAD/NURBS/solid geometry as appropriate
* Maintaining critical edges, mounting locations and fitment geometry
* Checking the reconstructed CAD against the original scan
* Preparing files suitable for our manufacturer's mould/tooling process
* Providing STEP, IGES, Parasolid or other appropriate manufacturing formats

### Experience required

We are specifically looking for someone with **proven scan-to-CAD / reverse-engineering experience**.

Automotive experience is highly preferred, particularly experience with:

* Automotive body and aero components
* Composite/carbon-fibre components
* Mould and tooling production
* Complex surface reconstruction
* Geomagic Design X, CATIA, Siemens NX, SolidWorks, Rhino or similar professional software

We are **not looking for a beginner or someone we need to guide through the reverse-engineering process**.

We will provide the scan data, reference photos and information about the component. We expect you to review the data and advise us on the appropriate reconstruction process and any additional information required.

### First project

We would like to begin with **one automotive component as a paid test project**.

If the quality of the work is good and the files are accepted by our manufacturer, there will be **ongoing work across multiple automotive components**.

### When applying

Please include:

1. Examples of previous scan-to-CAD / reverse-engineering work.
2. Automotive or composite-part examples if available.
3. The software you use.
4. A brief explanation of your process for converting an STL/mesh scan into manufacturing-ready CAD.
5. The final CAD formats you can provide.
6. Your approximate turnaround time for one automotive component.

**Please do not apply if your experience is mainly rendering, animation or general 3D modelling. We specifically need reverse-engineering and manufacturing CAD experience.**

Convert a project to a step 3D printable production model with alterations

I’m looking for a skilled full-stack software engineer to improve and complete my existing Next.js/React website and eventually build a mobile app for Prospect Network, a baseball tournament and sports media platform. You should be comfortable working with an existing codebase, strengthening the backend and API, improving database performance, and building reliable authentication and scalable architecture. The goal is to turn the platform into a polished, dependable product that supports ongoing growth and future mobile development.

Furne is developing a premium men's T-shirt and we're looking for an experienced apparel technical designer / tech pack specialist to create a detailed, factory-ready tech pack.

Our design direction is inspired by the quality and refinement seen in premium contemporary menswear, with particular attention to fit, fabric hand-feel, neckline construction, drape, stitching, washing, and overall garment finishing. However, this will be an original Furne product with its own specifications and identity.

This is not a basic graphic T-shirt project. We need someone who understands garment construction, knit fabrics, pattern development, grading, and apparel manufacturing.

What We Will Provide

We can provide:

- Design/reference images
- Our creative direction
- Reference garments or measurements where available
- Branding and artwork details
- Desired fit and overall aesthetic

Your role will be to translate these references into clear, precise production specifications that an apparel factory can use to develop consistent samples and production.

Tech Pack Requirements

The final tech pack should include:

- Professional front and back technical flats
- Detailed construction callouts
- Complete POM measurement/specification chart
- Graded size specifications and grade rules
- Measurement tolerances
- Fabric composition and specification
- Recommended/specified GSM

- Complete BOM
- Trims and labels
- Branding/artwork placement
- Colorways
- Packaging specifications
- Factory notes and production instructions

Key Focus

The T-shirt block, proportions, neckline, and overall fit are extremely important to us.

We want a refined premium fit with clean construction and elevated finishing—not the proportions or construction typically found in generic promotional or blank T-shirts.

Experience translating a physical or visual reference garment into accurate technical specifications will be a strong advantage.

Sample Review

Ideally, the selected designer should also be available to review the first factory sample and provide technical/fit corrections where necessary.

This may include identifying issues with:

- Body proportions
- Neckline shape and depth
- Sleeve length and opening
- Shoulder placement
- Hem position
- Fabric behavior
- Stitching/construction
- Overall fit and balance

Ideal Candidate

You should have:

- Professional experience creating production-ready apparel tech packs
- Strong knowledge of men's T-shirt and jersey construction
- Understanding of knit fabrics, GSM, rib specifications and fabric behavior
- Patternmaking and garment fit knowledge
- Ability to create accurate POM charts and grading specifications
- Understanding of seams, stitches, SPI and tolerances
- Experience working with apparel manufacturers/factories
- Strong technical communication skills
- Experience with premium fashion or contemporary menswear is preferred
- Experience reverse-engineering or analyzing reference garments is a plus

Please include examples of previous T-shirt, jersey, or menswear tech packs in your proposal.

We are looking for someone who can work with Furne beyond simply drawing the garment someone who understands how to turn a design concept into a product that can actually be sampled and manufactured accurately.

US marketing agency running a portfolio of client accounts on GoHighLevel, n8n, and Shopify. We're adding one person to own funnel and automation builds end to end.

End to end means you get a goal, not a spec. You work out the build, make it, test the edge cases, and hand it back working. Landing page through form through CRM pipeline through automation through tracking. If any layer of that is a handoff for you, this isn't the right role.

The work is a mix of new builds and fixing things already live in client accounts. Some weeks are one large build, some weeks are five small ones.

You should be strong in all three of these:

- GoHighLevel: funnels, forms, workflows, pipelines, custom fields and objects, and the API when the UI can't get there
- n8n or equivalent: webhooks, HTTP nodes, code nodes, error handling
- Front end: enough HTML, CSS, and JavaScript to build a custom page and make it look right, not just stack prebuilt blocks

Helpful but not required: Shopify, Supabase, Meta pixel and CAPI.

How we work: async, documented, Loom-driven. We maintain a large internal library of written build standards that you'll be handed on day one, so you won't be reverse-engineering how we do things. We're an AI-forward shop, Claude and Cursor are part of daily work here.

Hiring in Latin America specifically for timezone overlap with US Eastern.

10 to 20 hours a week to start, with room to grow into more.

I am looking for an experienced CAD/product designer with manufacturing experience to develop an original set of 4-inch uppercase letters that will be used to manufacture master patterns for silicone molds.

This is not a simple vector-tracing or graphic-design project. The final files need to be clean, dimensionally consistent, editable, and suitable for physical manufacturing.

Project Background

I currently use an existing set of silicone letter molds and like their overall proportions, stroke weight, appearance, and usability. I would like to use these as a visual reference to develop my own original alphabet with a similar overall style and proportions, rather than directly copying the existing design.

I do not know the original font, exact stroke widths, corner radii, or other dimensions. Determining appropriate geometry and developing a consistent lettering system will be part of the project.

I can provide:

* Photos of the complete existing alphabet
* Detailed close-up photographs
* Measurements as needed
* Finished resin letters
* Existing silicone mold samples
* Physical samples by mail if necessary

I would prefer not to ship the entire alphabet. Please explain what photographs, measurements, or representative physical samples you would need.

Intended Manufacturing Process

The general process will be:

CAD/vector artwork → physical 4" master patterns → silicone molds → cast resin letters

The physical masters need to produce smooth, professional molds and finished resin castings. Clean curves, consistent geometry, appropriate corners/radii, and manufacturing accuracy are therefore important.

I am interested in working with someone who understands designing for CNC, laser cutting, molds, reverse engineering, or similar manufacturing processes, rather than someone who only creates graphic artwork.

Initial Scope

The primary project is:

* Uppercase A–Z
* Ampersand (&)
* Approximately 4" finished letter height
* Consistent design language throughout the complete alphabet

Additional characters, sizes, and designs may be commissioned as future projects, but A–Z and & are the priority for this project.

Paid Test / First Milestone

I would like to begin with one production-ready test letter (likely M) before committing to the complete alphabet.

The test letter should be developed using the same process and standards that would be used for the full alphabet.

I expect to:

1. Review the initial design digitally.
2. Allow up to two reasonable rounds of revisions.
3. Have a physical master manufactured.
4. Produce a silicone mold from the master.
5. Cast a resin test letter and evaluate the finished result.

Because physical manufacturing and testing are involved, there may be approximately 14–21 days between initial design approval and final physical validation.

If the test is successful, the intention is to proceed with the remaining alphabet and ampersand.

Final Deliverables

I would like a complete manufacturing/source package including appropriate versions of:

* DXF
* SVG
* Adobe Illustrator (AI)
* PDF
* Native/editable CAD or design source files

I am open to recommendations regarding the best native CAD/design format and appropriate manufacturing tolerances.

The important requirement is that I receive the editable source files and production-ready exports, allowing the designs to be manufactured again or modified in the future without depending on a particular designer or manufacturer.

Ownership

Upon completion and payment, I require full commercial rights and ownership of the final project-specific designs, artwork, CAD/vector files, and editable source files.

The finished alphabet may ultimately be used in products that are sold commercially, including silicone molds.

When Applying

Please include:

* Examples of relevant CAD, CNC, laser-cutting, reverse-engineering, mold-design, or manufacturing work.
* The software you would use for this project.
* Your proposed fixed price for the one-letter test milestone.
* Your proposed fixed price for completing A–Z + & after the test design is approved.
* Estimated design turnaround time.

Most importantly, please answer this question:

How would you approach developing an original, production-ready alphabet based on an existing physical reference product, and what photographs, measurements, or physical samples would you need from me?

I am looking for the best combination of manufacturing knowledge, design quality, communication, and value, rather than simply the lowest bid.

Successful completion of this project could lead to additional work involving other sizes, fonts, numbers, symbols, and related mold products.

Roofing Media Buyer (Meta Ads)

Role: Paid Media Strategy & Ad Account Ownership (Roofing / Home Improvement, Meta Only)

Location: Remote

We're looking for a Meta media buyer who thinks like a growth partner, not a button pusher.
Someone who has already spent real money on Meta in the roofing and home improvement space, knows what a qualified roofing lead actually looks like, and can walk into an ad account on day one and start scaling it without hand holding.

This is not a "launch the campaign and check on it Monday" role. This is full ownership of Meta paid media performance for our roofing and home improvement clients.

REQUIREMENTS: you MUST have at least 2+ years of hands on Meta media buying experience with a heavy focus on roofing, home improvement, or local home services. This role is strictly Meta (Facebook + Instagram).

We are not looking for Google, TikTok, or generalist buyers. Must be able to show real case studies with real numbers, including spend, CPL, lead to appointment rate, cost per booked job, and ROAS. Must know the roofing customer inside and out: storm vs. retail, insurance vs. cash, full replacement vs. repair, and how creative and targeting shifts across each. Must be fluent in Meta Ads Manager, CBO vs. ABO strategy, Advantage+ campaigns, creative testing frameworks, instant forms vs. landing page lead flows, custom/lookalike audiences, and offline conversion tracking / CAPI.

Must understand the full funnel, not just "cheap leads," but leads that actually book and close. MUST be a self starter. No "wait for us to tell you what to test." The goal is to make our clients' accounts print, to be the person who sees the numbers before we do and is already fixing what's broken.

Also must be obsessed with the craft, studying winning roofer ads in the Meta Ad Library, reverse engineering competitor funnels, and bringing fresh angles weekly. Be sharp, be accountable, be organized, and most of all: be pleasant to work with.

Compensation & Growth: This role starts with a set rate per client, but if performance is strong there is a clear pay increase built in, plus first access to every new client we onboard. We're actively expanding the agency, so the right buyer will grow with us: more accounts, higher pay, and a long term seat as we scale. If you perform, you win.

If that's you, submit and we'll reach out to you!

IMPORTANT: To apply, you MUST submit a short video (Loom, Google Drive, YouTube unlisted, or similar) where you answer ALL of the questions below on camera. In the same video, clearly walk us through exactly how you would scale a roofing campaign from launch to scale, and how you would help the roofing client actually close deals within the first 30 days. We want to hear your strategy, your thinking, and your voice. Written only applications and text answers will not be considered.

1. Which roofing or home improvement clients have you personally run Meta ads for, and what results did you get? Names, spend, CPL, and any close/booking data you have.

2. Where can we find your case studies, screenshots of Meta Ads Manager (account level view preferred), or portfolio deck?

3. What's your winning Meta creative formula for a roofer right now, hook, angle, format, and why do you think it's working?

4. What's the lowest CPL you've hit for a roofing client on Meta, at what monthly spend, and how did you get there?

5. Your exact plan to scale a roofing campaign and help the client close deals in the first month.

Paste the link to your video here:

What makes this Role special?

✦ Real ad budgets and real clients. You'll be scaling active Meta accounts, not pitching theory.

✦ Clear growth path: strong performance = pay increase + first pick of new clients as we expand.

✦ Long term seat on a growing agency with a path to lead media buyer as we add accounts.

Your Responsibilities

✧ Own Meta paid media for our roofing and home improvement clients: strategy, campaign builds, launches, daily optimization, scaling, and reporting.

✧ Run the full Meta testing pipeline: audience, creative, offer, instant form/landing page, follow up feedback loop with the client's sales team.

✧ Brief the creative team on what to shoot and design next based on what the data is telling you (or produce your own creative direction if you have that muscle).

✧ Hit and defend client KPIs: CPL, lead quality, booked appointments, and cost per closed job, and communicate performance clearly week over week.

✧ Stay ahead of the space: Meta platform changes, new ad formats, iOS/tracking updates, competitor teardowns in the Ad Library, and roofing specific seasonality (storm season, insurance cycles, etc.).

have a working RF receiver board with stable firmware, but the companion transmitter board is unusable because the only Gerber and BOM I was sent are corrupted. The transmitter’s firmware binary is intact, so the new hardware must accept that code without modification and still communicate flawlessly with the existing receiver over our RF data-transmission link.

What I can supply:
• The corrupted Gerber and BOM as rough references
• High-resolution photos of the original populated transmitter board
• The receiver board’s schematic and dimensions
• The compiled transmitter firmware (HEX)

Your task is to recreate the complete transmitter design from the ground up—clean schematic, PCB layout, production-ready Gerbers, pick-and-place files, and an updated BOM—so it drops straight into manufacture and works first time with the current firmware on both ends.

Acceptance criteria:
• DRC-clean Gerbers that open error-free in KiCad or Altium
• BOM with current part numbers and at least two viable suppliers for key components
• Proven impedance-matched RF path and antenna interface consistent with the receiver’s expectations
• Design walkthrough followed by successful firmware load and on-bench communication test between new TX prototype and existing RX board

If you’re comfortable reverse-engineering from limited documentation and have solid RF layout experience, I’d love to get this board back into production quickly.

I need a Windows DLL that Flexscan 3D can load at runtime so the software can drive a Revopoint Dual Turntable. You may start from, or simply reference, the open-source controller code here: https://github.com/opensourcemanufacturing/Revopoint-Dual-Turntable.

Core behaviours
• Start and stop rotation on command
• Adjust rotation speed dynamically
• Keep the table’s position in-sync with each scan trigger coming from Flexscan 3D
• (Nice-to-have) expose a tilt-angle routine so I can script multi-axis captures later

Interface expectations
Flexscan 3D talks to plug-ins through a plain C-style DLL entry point. I can share sample calls that the software issues; however, there is no official SDK, so you will be doing a bit of reverse-engineering or wrapper work. As long as the exported functions you create respond with the right return codes, Flexscan will recognise them.

Turntable comms
The Revopoint board is driven over USB-serial via bluetooth. Their GitHub project already contains packet formats for speed, direction and stop commands, so you can borrow that logic or rewrite it in cleaner C/C++⁠/⁠C#. The DLL must open, configure and close the COM port cleanly so Flexscan never locks up.

Deliverables
1. Compiled 64-bit DLL ready to drop into Flexscan’s “plugins” folder
2. Full source code with build instructions (Visual Studio solution preferred)
3. A short README explaining the exported functions and any parameters Flexscan should pass
4. A test console or script that demonstrates all four features outside Flexscan

Acceptance
I will consider the job complete when the DLL lets me:
• launch Flexscan, press “scan”, and see the table rotate in step with frame capture;
• modify rotation speed from within Flexscan without reconnecting;
• stop the table instantly when scanning ends;
• invoke the tilt-angle command from the demo script and confirm movement.

If you are comfortable with serial protocols, C/C++, and plugin development, this should be a focused task. Let me know any questions and the approximate timeline you need.

We are developing a premium men's T-shirt and are looking for an experienced apparel technical designer / tech pack specialist to create a complete, factory-ready tech pack.

Our quality and construction benchmark is Osklen, particularly their premium men's T-shirts. We are looking to achieve a similar level of attention to fit, fabric, neckline construction, stitching, wash/softness, drape and overall finishing — while developing our own product and specifications.

This is not simply a graphic T-shirt project. We need someone with a strong understanding of garment construction, pattern development, knit fabrics and production.

We can provide reference images, our design direction and ideally measurements/reference garments. We want the selected freelancer to help translate these references into a precise specification that a factory can sample and manufacture consistently.

The final tech pack should include technical front/back flats, detailed construction callouts, complete POM measurement chart, graded size specifications/grade rules, measurement tolerances, fabric specification, GSM recommendation/specification, rib specification, neckline construction, seam and stitch specifications, SPI, seam allowances, sleeve and hem construction, wash/finishing requirements, BOM, trims and labels, artwork/branding placement, colorways and packaging details.

A major focus will be getting the T-shirt block and neckline correct. We are looking for the refined fit and finishing associated with premium Brazilian designer T-shirts rather than a standard promotional/blank T-shirt.

The selected designer should also be able to review the first factory sample and provide fit/technical corrections if needed.

Ideal candidate: You have professional experience creating production tech packs for premium fashion or contemporary menswear brands; understand jersey T-shirt construction and patternmaking; can specify fabrics, ribs, stitches, tolerances and grading rather than simply illustrating garments; and have experience communicating with overseas apparel factories.

Experience reverse-engineering a reference garment into a production specification is highly desirable.

We need a senior ML engineer to design and train a production-quality model from messy, real-world data. This is not a notebook demo. We need a well-reasoned model, a rigorous evaluation setup, and a clear record of what was tried and why.
The problem We have a labeled dataset with class imbalance, noisy labels, and mixed feature types (structured fields plus free text). The goal is a model that generalizes on unseen data, not one that only looks good on a random split.
What you’ll do
Audit the dataset: leakage, label quality, missingness, outliers, and train/validation/test design
Build a reproducible preprocessing and feature pipeline (structured features + text embeddings if useful)
Train and compare several approaches (e.g. gradient boosting, linear baselines, and a neural/transformer option)
Handle imbalance and noisy labels with the right sampling, loss, or calibration methods
Run proper validation (stratified or grouped splits — no row-level leakage)
Error analysis: where the model fails, which classes confuse, and what would improve it next
Deliver trained artifacts, training/eval code, metrics, and a short technical write-up
Success looks like
A holdout evaluation you can defend (precision, recall, F1, PR-AUC, calibration)
A baseline vs. final model comparison, not a single lucky run
Code someone else can retrain without reverse-engineering your notebook
What we’re looking for
Senior experience building models in Python (PyTorch or TensorFlow, scikit-learn, XGBoost/LightGBM, pandas)
Strong instincts on validation design, leakage, and overfitting
Comfortable with both classical ML and deep learning; pick the simpler model if it wins
Clear written communication and independent execution
NLP / transformer experience is a plus
To apply, send 1–2 relevant model-build case studies (what the data looked like, what you tried, and the final metrics) plus your rate.

I need support to create and print a discontinued metal 3D part for an air conditioner exhaust system. The project involves reverse engineering and manufacturing a specific part. The ideal candidate should have experience in 3D printing and metal fabrication.

The cost is to cover
- the time to research + create the CAD file
- submit the order to metal working shop
- work with client (me) until the final part works

The cost does not cover the actual cost to print the piece (I will pay seperately)

this is the part I need (the large metal piece that connects to the unit)

We're hiring an autonomous Senior Full-Stack Engineer to own web and mobile development end to end — backend architecture through polished UIs. You'll build scalable Node.js/TypeScript services (Express, NestJS), high-performance React and React Native frontends, manage iOS/Android release pipelines, and integrate third-party APIs and payment gateways. Requirements: 6+ years commercial experience, a completed Computer Science (or equivalent) degree, SQL/NoSQL design, microservices, production-proven React Native, and exceptional written and spoken English. You must have held a role at an established engineering organization — not freelance work only. You must currently reside in North or South America with full overlap to Los Angeles (Pacific) hours. Hourly contract, 40–80 hrs/month, occasional full-time capacity. Nice-to-have: fintech/PCI, Web3, Bun/Biome/Hono. Recent grads and bootcamp-only portfolios won't be considered.

***Project Overview:
-We are looking for a capable Python developer to build a data ingestion script that parses two specific types of undocumented binary files into structured Pandas DataFrames or clean CSVs.
-These files contain high-frequency, time-series sensor data. There is no official API or documentation for the file structure. However, we will provide the raw binary files alongside "known good" manual CSV exports. Your goal is to write a script that reads the binary and perfectly reproduces the provided CSV output.

***Key Scope & Requirements:
-Binary Data Parsing: Analyze the binary files to map the byte-offsets for the headers and the core data payload.
-Data Unpacking: Decode the packed byte structures (floats, integers, bitmasks) and align them to a common time-base.
-Format A & Format B: There are two distinct file types to decode.
-Validation: Your script's output must perfectly match the values in the manual reference CSVs we provide.

***Tech Stack & Deliverables:
-Language: Python (using libraries like struct, numpy, or construct).
-Environment: A standalone Python script or set of functions (no UI, desktop app, or complex architecture required).
-Deliverables: Clean, commented Python code that takes a binary file as input and outputs the formatted CSV, along with brief notes on how the offsets were mapped.

***Ideal Candidate:
-Strong Python skills with specific experience reading and unpacking binary files (.bin, .dat, etc.).
-Comfortable analyzing byte structures and finding data patterns to match the reference exports.
-Experience with IoT, automotive, or drone time-series logger data is a plus, but not strictly required.

Need production prototype, manufacture package , manufacturing sourcing if available

I am building an integrated volt-ampere meter that also serves as a protection and control module for a pump system. The unit must:

• Measure voltage and current accurately while reacting instantly to high/low-voltage and over/under-current conditions (these three protections are the top priority).
• Manage a water-level subsystem that reads three stainless-steel probes plus one flow sensor, then drives two relays—one energises the starter circuit, the other keeps the motor running.

Scope of work
1. Circuit and PCB: create the full schematic around a MindMotion MM32G0001A1T (or any other MM32 in the same family so our inventory stays unchanged), layout a compact single-board solution, and specify a CC display already stocked in-house.
2. Firmware: write clean, well-documented code that handles measurement, protection logic, probe sensing, flow-rate interpretation, relay timing and user indications on the CC display.
3. Hand-over: deliver schematics, BOM, PCB Gerbers, pick-and-place, compiled hex, full source, and brief production test procedures so I can program and deploy the boards without reverse-engineering anything.

Acceptance
The assembled prototype should:
– Trip within the specified thresholds for voltage and current;
– Halt the motor on dry-run or low-water;
– Recover gracefully when values return to the safe band;
– Drive the starter relay for the required soft-start window, then latch over to the run relay.

I want the circuit and firmware phases tackled first, followed by display fine-tuning. If you have the expertise to take the project from schematic to working code and are comfortable with MindMotion MCUs, let’s move

I need Technical advice on the best architecture
Development of the automation pipeline
Testing and debugging support
Possible maintenance for future updates

What we need
We're hiring an experienced penetration tester to perform an authorized, full-stack security assessment of our production and/or staging environments. The goal is simple: find the vulnerabilities before someone else does, prove they're exploitable, and give us a clear path to close them.

This is a hands-on offensive security engagement, not an automated-scan-and-report job. We want a tester who thinks like an attacker and challenges our business logic.

Scope

Public website and web application (customer + merchant/partner flows)
Native mobile apps (iOS and Android)
Backend REST/GraphQL APIs and third-party integrations
Authentication, session management, and account/role separation
Cloud/hosting configuration and exposed infrastructure

Priority test areas

Payment security — high priority. Attempt to bypass or manipulate the payment flow: complete a booking without paying, tamper with prices/amounts/currency, replay or forge payment confirmations, exploit callback/webhook handling, and abuse discount, refund, or commission logic.
Ticket issuance — high priority. Attempt to generate, duplicate, forge, or reuse tickets/vouchers without a valid paid booking; test QR/booking-reference validation and redemption controls.
Broken access control / IDOR — accessing or modifying other users', merchants', or admins' data and bookings.
Business logic abuse — booking race conditions, negative quantities, inventory/availability manipulation, commission and payout tampering.
Injection & input handling — SQLi, XSS, SSRF, command/template injection, insecure deserialization.
Authentication & session flaws — weak login/OTP flows, token handling, privilege escalation, password reset abuse.
Mobile-specific — insecure local storage, hardcoded secrets/keys, cert pinning bypass, insecure API calls, tampering/reverse-engineering resistance.
API security — rate limiting, mass assignment, excessive data exposure, broken object/function-level authorization.

Deliverables

A detailed report of all findings, each with severity (CVSS), reproduction steps, evidence/PoC, and impact.
A prioritized remediation plan with concrete fix recommendations.
A retest/verification pass after our team applies fixes, to confirm each issue is closed.
A short executive summary suitable for non-technical stakeholders.

Requirements

Proven web + mobile application penetration testing experience (please share sanitized sample reports or redacted PoCs).
Strong grasp of the OWASP Top 10, OWASP API Security Top 10, and OWASP MASVS/MSTG for mobile.
Relevant certification is a plus (OSCP, OSWE, eWPTX, GWAPT, CEH, or equivalent).
Familiarity with payment/booking/ticketing systems and their fraud vectors.
Excellent written English; Arabic is a plus.

Rules of engagement

All testing must be authorized, scoped, and coordinated with our team in advance — testing only against systems and environments we designate.
No destructive actions, no real customer data exfiltration, no denial-of-service against production without written approval.
Findings and any data accessed are strictly confidential; you'll be required to sign an NDA before access is grante
