Freelance python jobs for world-class Developers

I am looking for an electronics engineer or senior lab technician based in Brazil to help me build and test a small run of analog sensor prototypes (resistive-capacitive divider boards). Part-time, remote, on your own bench.

What you will do

- Assemble boards by hand: SMD parts 0603 to 1812, plus a few through-hole parts
- Inspect parts before assembly: small capacitors (pF) and high-value resistors (MΩ), with every value recorded
- Run the tests from a written procedure: gain and phase from 10 Hz to 10 MHz, insulation resistance, a simple transient check
- Write a short test report in English with photos, raw data and a pass/fail result for each test

You must have

- Clean, reliable SMD hand soldering
- Hands-on experience with an LCR meter at pF level (open/short compensation, fixture effects)
- Experience with a frequency-response analyser or VNA (Bode 100 or similar) and with probe and load effects
- Basic measurement-uncertainty thinking: you know when a result is too close to the limit to call
- LTspice and Python (numpy, matplotlib) to compare your results with a model; KiCad reading is a plus

Your bench

- Oscilloscope (100 MHz or more), function generator, LCR meter, multimeter, soldering station, magnifier
- No instrument purchases. If you don’t own the gain-phase analyser or the insulation tester, you borrow them or arrange access to a lab in Brazil (university, IFPE, SENAI or similar) yourself. Tell me which in your proposal.


Other

- You must be located in Brazil
- Communication in Portuguese or English; reports in English
- NDA required before any project details are shared

To apply, send:

- Your instrument list (models), marking which you own and which you would borrow or use at a lab, and where
- A photo of SMD work you soldered yourself
- One short example of a measurement where the probe, cable or fixture changed the result, and how you corrected it


Screening questions

- Which instruments do you own, and which would you borrow or use at a lab in Brazil? Name the lab.
- How do you measure a 10 pF capacitor with an LCR meter and remove the fixture capacitance?
- A result is 1.6 % against a 2.0 % limit and your measurement uncertainty is ±0.5 %. Pass or fail, and why?

I attached the "Plan of Action" and the Invoice. Please advise.

Hello, I’m looking for an experienced Flutter/Firebase developer or development team to help me complete, improve, and launch my existing mobile application, TreeLogic.

The app has already been developed, so I am not looking to start from scratch. I need someone to review the existing code, fix bugs, finish incomplete features, improve the design and functionality, and prepare it for launch on iOS and Android.

I want to explain my entire vision upfront so there are no surprises about what the project involves.

Here is everything I want TreeLogic to include:

1. Tree Identification Using Photos and AI: Users should be able to take a picture of a tree or upload a photo, and the app should identify the likely species, common and scientific names, characteristics, growth information, care recommendations, and possible visible diseases or problems. The app should explain when identification is uncertain.

2. Accurate City Tree Ordinances and Permits: This is extremely important. The app needs to identify the correct city or jurisdiction based on the property address and provide accurate tree removal and trimming permit requirements, including protected species, trunk diameter measurements, exemptions, and official city ordinance information. I want direct links to official city permit applications and clear step-by-step instructions. We will initially focus on Fremont and the surrounding Bay Area, eventually expanding throughout all nine Bay Area counties, California, and nationwide. All ordinance information must be verified and easy to update.

3. Permit Application Assistance: I want homeowners to easily understand whether they need a permit and what documents, measurements, photographs, or arborist reports are required. The app should guide them through the application process and connect them directly to the correct city permit portal.

4. Connect Homeowners With Tree Companies and Arborists: Homeowners should be able to request estimates for tree trimming, removal, planting, stump grinding, and other tree services. They should be able to upload photographs, describe their project, and connect with participating tree companies or certified arborists in their area.

5. Paid Monthly Subscriptions for Tree Companies: This is one of my main business goals. Homeowners should be able to use the basic app features for free, but tree companies should pay monthly or annual subscription fees to access the full business features. These may include company profiles, customer leads, estimate requests, notifications, business dashboards, and other premium tools. I want different subscription levels, secure recurring payments, and the ability to adjust prices and features as the business grows.

6. Free Wood Chip Exchange: I want a section where homeowners can request free wood chips and tree companies can post when they have wood chips available. Homeowners should be able to enter their location and request deliveries, while companies can post availability, quantities, locations, and delivery options. This should help companies reduce disposal costs and help homeowners obtain free wood chips. Homeowners should access this feature for free, while business features can be included in paid subscriptions.

7. Owner-Controlled Admin Dashboard: I want full control over the application without constantly needing a developer. I need to manage users, tree companies, subscriptions, pricing, city ordinances, permit links, service requests, wood chip listings, notifications, and app activity.

8. Professional Design and Easy Navigation: The app should look modern, professional, and be simple enough for homeowners who know nothing about trees or city permits. It must work smoothly on iPhone and Android.

9. Security and Scalability: I want the existing Firebase backend reviewed and properly secured. The database, authentication, payment processing, photo storage, and user information must be protected. The app should be designed to expand to additional cities and states without requiring a complete rebuild.

10. Testing and App Launch: I need all features thoroughly tested, including login, tree identification, permit information, estimate requests, subscriptions, payments, and the Wood Chip Exchange. I also need assistance publishing the finished application to the Apple App Store and Google Play Store.

11. Full Ownership: I must retain complete ownership and administrative access to the source code, Firebase project, database, developer accounts, payment systems, and everything related to TreeLogic.

12. Project Phases and Budget: I understand this is a large project, and I am open to completing it in phases. My first priority is finishing the existing app, fixing problems, verifying city permit information, and getting a reliable version launched. The subscription system, Wood Chip Exchange, expanded city coverage, and additional advanced features can be organized into clearly defined phases.

Before hiring anyone, I need the following:

* A review of the existing app and source code.
* A clear explanation of what is already working, what needs fixing, and what needs to be developed.
* An itemized price for each phase and feature.
* A realistic timeline and specific deliverables.
* Information about your experience with Flutter, Firebase, AI integration, payment subscriptions, and app publishing.
* Any additional costs for APIs, AI services, hosting, or payment processing.
* A milestone-based payment arrangement, with work tested and approved before payment.
* Written approval required for any additional charges or changes in scope.

My ultimate goal is to turn TreeLogic into a nationwide platform that homeowners, arborists, and tree service companies can rely on for tree identification, city permit requirements, professional services, and wood chip exchange. I also want to build a profitable business through paid subscriptions for tree companies.

I am looking for someone experienced, honest, dependable, and interested in helping me build this correctly for long-term success.

Please review everything carefully and let me know your proposed approach, estimated costs, timeline, and recommendations.

Thank you!

Tradeflow is hiring Platform Integrity Analysts to start immediately. Remote, contract, 3 to 8 weeks.

ABOUT TRADEFLOW
Tradeflow is the AI-native procurement-to-payment layer for South African hospitality. Restaurants, bars and hotels order, receive and capture supplier deliveries digitally, without replacing their POS. Our products are live with customers now, so data integrity is crucial to value proposition.

Data capturing accuracy makes that data trustworthy; it is also what takes a new site live - on time.

THE ROLE
You'll join a bench of detail orientated analysts who keep our data accurate, improve the workflows behind it, and turn what they find into reports our engineers can act on. You capture and validate; you analyse what goes wrong; you write it up. Our Head of Data prioritises your findings for engineering, and you check each fix on live data.

WHAT YOU'LL DO
- Review captured data against our accuracy targets, and log every miss with its cause
- Map supplier requisitions, invoices to ERP products, and correct mapping errors as you find them
- Help write and maintain the SOP for invoice mapping and the workflows for resolving mismatches
- Propose capture principles that keep data entry consistent, and help train new capturers as the team grows
- Write bug reports engineering can reproduce first time: steps, screenshots, expected versus actual, and how many invoices or venues are affected
- Log feature requests with the problem, who it affects, the proposed change and the value
- Analyse error patterns by supplier, document format and layout; find the root cause and propose fixes
- Do occasional field work at venues in Cape Town metro and the Winelands, scheduled in advance, ending in a written field report

WHAT GOOD LOOKS LIKE
- Matching accuracy at 98% or higher on periodic checks
- Bug reports and feature requests that need no follow-up questions
- An SOP clear enough that the next analyst can start from it without a verbal hand-over
- On-demand work picked up within the agreed turnaround, with early warning when a deadline will slip

YOU'LL THRIVE HERE IF YOU ARE
- Meticulous with data; you spot the line item that is off by one unit
- A clear writer
- Process-minded; a repeated mistake is a workflow problem you go and fix
- Comfortable in spreadsheets; basic Python is a plus; SQL and R help but are not required
- Curious about how hospitality runs: deliveries, supplier invoices, POS product lists
- Self-managing, diligent and trustworthy; you will work with live customer data
- Able to get to venues in Cape Town for occasional field work

We welcome bigger ideas too. If you see a product-led way to solve a problem you uncover, even outside your core function, write it up as a proposal. Proposals to improve the data pipeline are judged on the quality and depth of the solution.

HOW WE WORK
- Remote and on demand; not a fixed daily shift
- Up to 45 hours a week, agreed per contract; a weekly timesheet showing the customer worked on and invoices captured
- A 3 to 8 week engagement, starting immediately after a short interview with our CEO
- South African candidates only; Cape Town is a plus for field work

TO APPLY
Answer the screening questions, and start your cover letter with the word "ledger" so we know you read this far.

I run an AI automation agency in South Africa building voice receptionists for dental practices. I have a working Retell AI voice agent and need a developer to connect it to GoodX (South African dental practice management software). The goal is for the agent to book, move and cancel appointments directly in the practice’s GoodX diary during a live call.

What the agent needs to do in GoodX

Check real-time availability per practitioner and appointment type
Look up existing patients (name, ID or phone number) and create new patient records when needed
Book appointments directly into the GoodX diary
Reschedule and cancel existing appointments

How it should work

Retell custom functions call an endpoint, and that endpoint talks to GoodX. I already use Make.com, so a Make-based middleware layer is preferred if it’s workable. A lightweight hosted service (Node or Python) is fine if Make can’t handle it.
Responses have to be fast enough for a live phone call (aim for under 2–3 seconds).
Errors must be handled cleanly: no slot available, patient not found, GoodX timeout. The agent should always have a fallback, such as taking a message or offering another time.

The main unknown
I haven’t confirmed whether GoodX offers an API or integration access to third parties. Part of this job is finding that out: contacting GoodX if needed, reviewing any documentation, and recommending the most reliable route. If there’s no API, tell me what the realistic alternatives are before you build anything.

The product
*Internal practice-management and clinical-operations platform for a telehealth provider. It sits as a middleware layer between our staff and the Healthie EHR
*Python/FastAPI backend + Next.js/React frontend in a monorepo, handling live PHI for real patients - not a greenfield project and not a prototype.
* Small team, high ownership. You will take features end-to-end: data model →API → UI → tests → deploy. You will not be handed pre-decomposed tickets.

What you'll work on
* Patient intake, chart notes, scheduling, and billing workflows used daily by clinical staff.
* Third-party integrations: EHR, clearinghouse/eligibility vendors, CRM, and form webhooks.
* An in-app clinical AI Copilot built on streaming LLM APIs.
Required experience
* Python 3.12 + FastAPI
* TypeScript + Next.js 15 (App Router) + React 19
* Zustand for client state, or other strong global state management experience
* GraphQL as a consumer - writing and debugging queries and mutations against a third-party API you do not control* REST/HTTP integration
* Unit testing with Vitest and Pytest
* Redis caching
* PostgreSQL / Supabase
* Git fluency

Strong plus
* US healthcare domain knowledge: insurance eligibility (EDI 270/271), payer and plan-type classification, Medicare vs. Medicare Advantage vs. Medicaid, MBIs, CPT/ICD-10, CMS-1500 claims.LLM application engineering: OpenAI/Anthropic APIs, streaming over SSE,tool/function calling, prompt design, token and cost control, multi-turn session persistence.
* CRM and webhook integration work: Zoho CRM REST v8, OAuth 2.0 client credentials, form webhooks.Observability: Sentry, PostHog, and log-driven debugging in a hosted environment.

How we work
* Strong written English. Most communication is asynchronous: PR descriptions, design proposals, written status. You need to explain a trade-off in writing without a call.
* Escalates early. When a spec is ambiguous or an approach is blocked, you raise it within hours instead of shipping a guess three days later.* Reads before writing. The repo carries extensive internal documentation —architecture notes, per-domain summaries, prior implementation plans. Search that context before proposing a design.
* Comfortable using AI coding agents (Claude Code)as part of the normal workflow — planning, implementing, and verifying with agent assistance, while staying fully accountable for the code you submit.
* Updates internal documentation as part of finishing a task, not as an afterthought.

Not required
* Mobile, Kubernetes/DevOps, ML training, or data-engineering experience.
* Prior US healthcare experience is a strong plus, but not a hard gate for an otherwise excellent Python/TypeScript integration engineer.

About QuickStop
QuickStop is a consumer lending company offering short-term loans across emerging markets, including Belize, Barbados and Panama. Much of our customer journey happens over phone calls and WhatsApp, so we have a wealth of funnel data and thousands of real customer conversations. We want to turn that into clear, actionable insight into where and why applicants drop off.

The role
We’re looking for an energetic, highly motivated data analyst to join us part-time (about 20 hours/week). You’ll combine classic funnel analytics with AI-powered analysis of call transcripts and WhatsApp conversations to find the bottlenecks in our loan application, conversion and sales process, and help us fix them. If you love digging into messy data, using AI creatively, and seeing your work change how a business runs, this role is for you.

What you’ll do

- Write and optimize SQL queries in BigQuery to analyze our funnel from first contact to funded loan
- Build and maintain Power BI dashboards that track conversion rates, drop-off points and sales performance across markets
- Use LLMs (e.g. Claude, GPT, Gemini) to classify, tag and summarize call transcripts and WhatsApp conversations at scale, covering things like customer objections, sentiment, unanswered questions, document issues and reasons for abandoning an application
- Connect conversation insights to funnel outcomes, for example which objections or topics predict a lost applicant
- Compare performance across countries, channels and sales agents to spot what’s working and what isn’t
- Turn findings into clear, prioritized recommendations for our sales and operations teams
- Build repeatable pipelines so this analysis runs regularly, not as a one-off project

What we’re looking for

- Excellent written and spoken English
- Strong SQL skills and hands-on BigQuery experience
- Proven experience building Power BI reports and dashboards
- Practical experience using LLMs for data analysis (prompt design, structured outputs, batch processing, checking accuracy). Tell us specifically how you’ve done this.
- Experience with funnel, conversion or sales analytics
- Ability to explain findings clearly to non-technical colleagues
- Self-starter energy: you take ownership, move fast and bring ideas, not just answers
- Comfort handling sensitive customer financial data responsibly

Nice to have

- Spanish proficiency (some of our customer conversations are in Spanish)
- Python for data processing or LLM API work
- Experience working with speech-to-text output or other conversational data

Details

- Part-time, about 20 hours/week, ongoing
- Fully remote, with some overlap with Central America and Caribbean business hours
Rate: open to proposals
Start: as soon as possible

To apply, please include:

- A short description of a project where you used AI/LLMs to analyze unstructured text (calls, chats, support tickets, reviews), and what the result was
- An example of a Power BI dashboard you’ve built (screenshot or link, anonymized is fine)
- Your approach in 2–3 sentences: if you received 10,000 call transcripts and our funnel data in BigQuery, what would you do in your first two weeks?
- Your level of Spanish, if any

Please start your proposal with the word “FUNNEL” so we know you read the full post.

We have about 60 help-center articles in
Markdown. We want a small Python agent that
answers questions using only those articles.

It must:cite the article and section it used for every
answer, say "I don't know" when the articles don't
cover the question, instead of guessing,
come with an eval script that runs 30 test
questions (we provide them) and reports
accuracy, how often it correctly says "I don't
know", and the average cost per answer.
Use the Claude API. Pick the retrieval setup you
think fits and tell us why.

Deliverables: a GitHub repo, a README with
setup steps, and the eval results.

Screening questions
1.Share an AI agent or RAG system you built
that real people used. What went wrong
once it was live?
2.How will you stop the agent from answering
when the articles don't cover the question?

A digital local news organization is hiring an editor to direct AI and data tools that produce story drafts, then verify, edit and prepare them for publication. Reports to the Editor-in-Chief.

The role: Publish minimum 15-25+ information/news piece per day
You set the daily slate, instruct the tools, and check every claim against primary sources before it moves. The tools do the gathering and first drafts; you decide what is worth covering, what is true, and what is ready to publish.
*we have our own AI systems in place.


What you will do
• Choose topics, geographies and formats for the daily and weekly slate.
• Write clear instructions for AI tools and refine them as you learn what works.
• Verify names, titles, figures, dates and quotes against agendas, reports and public datasets.
• Check for duplicate coverage and stale or recycled signals.
• Edit for accuracy, fairness, clarity and house style.
• Build data-driven stories from public open-data portals, stating limits and avoiding claims the data cannot support.
• Prepare drafts in a CMS: categories, headlines, SEO fields, images and social captions.
• Escalate legal and ethical risks before publication.
• Log tool errors and work with the product team on fixes.
What you bring
• 3+ years in news editing, reporting or producing, with accurate work under deadline.
• Strong news judgment and a reflex for tracing every number to its source.
• Fast, clean writing and editing; AP-style fundamentals.
• Comfort with spreadsheets and public datasets.
• CMS experience, ideally WordPress.
• Experience directing AI tools, or the discipline to learn quickly: testing outputs and spotting confident errors.
• Knowledge of local government: councils, boards, budgets, public meetings.
• Preferred: SQL or Python, SEO and social distribution, and familiarity with the region we cover.

What you will not do
Publish unreviewed machine output, or present an inference as a finding

We are a small, options-focused investment firm building an intraday SPX 0DTE options program. We want a senior quant to help find and prove the strategies that go into it.

THE GOAL
A library of small intraday sub-strategies on SPXW 0DTE options, each selected and sized in real time by a micro-regime layer, on horizons from minutes to the full session, with no overnight positions. Every sleeve has to earn its place net of real execution costs.

WHAT IS ALREADY BUILT
- Data: SPXW quotes at one-minute and one-second resolution from 2022, trade prints paired with the quote at each trade, SPX and VIX index prints, ES, NQ and RTY futures, ETF bars and quotes, NYSE TICK and TRIN, VIX futures, and a daily forward capture of live SPXW quotes.
- A custom event-driven backtester: fills at the executable bid or ask (never the midpoint), a required time-to-expiry convention for every Greek, deterministic reruns verified by hash, look-ahead ("future-poison") tests and an append-only audit log.
- Research discipline: criteria-first registration, protected holdout windows, logged search histories, multiple-testing controls (deflated Sharpe, family-wise alpha spending) and blind replication of designated results.
- Causal change-point features (CUSUM and Bayesian online change-point) and a genetic-algorithm search prototype tested against an equal-budget random search on synthetic planted-edge data. Validation of the full regime-switching procedure is in progress.
- AI-assisted implementation and review (Claude Code and Codex agents), CPU and GPU research servers, self-hosted CI, paper-trading broker connectivity and an operations console.

WHERE WE ARE
Our broader research record contains more than 120 distinct ideas and more than 1,400 exploratory trial configurations across several research areas. We want a senior researcher who will challenge our assumptions, propose original hypotheses and own rigorous validation.

WHAT YOU WILL DO
1. A paid review of our research record and engine, ending in an agreed, prioritized hypothesis and testing plan.
2. Write each hypothesis as a short spec with pass and kill criteria before any test, then build and test it with us.
3. Help build the regime-switching portfolio layer and carry survivors through holdout and paper trading.

YOU HAVE
- Hands-on experience researching or trading intraday SPX, SPXW, XSP or ES options.
- Deep knowledge of 0DTE microstructure: spreads, fills, order types, PM cash settlement, intraday Greeks.
- Causal regime detection (change-point, HMM, realized-variance models, intraday seasonality) and a healthy fear of overfitting.
- Strong Python (pandas or polars, NumPy, DuckDB), tests and git; comfortable working alongside AI coding agents.
- Nice to have: OPRA-level quote and trade data, production broker APIs, order-flow research, ML for tabular time series.

ENGAGEMENT
Paid hourly, about 15 to 30 hours a week, remote, with agreed overlap during US market hours. You work directly with the principal, with a weekly review. NDA and IP assignment required. Work runs on our infrastructure.

I'm looking for a Python developer to build a simple AI-powered FAQ chatbot for a small business.

The chatbot should answer customer questions using a predefined collection of FAQs and business information. I want a lightweight prototype that I can run locally and test before considering a larger implementation.

This is a small project with a limited budget, so I'm looking for someone who can deliver a straightforward solution without unnecessary complexity.

I'm looking for an experienced python developer with AI experience who can handle the assessment successfully. There are 5 questions: 4 selection and 1 coding. I think it won't take a lot of time since questions are not complicated one. But it's required to be hand-written and explanations of each selection properly. Our expected budget is small. But if it goes well, you will be hired for next steps. Only apply if you are comfortable with our budget.

Hi, I run THE BEAST GYM, an immersive fitness studio in Lawrence, Massachusetts, USA. Our training room projects life-size content on three walls. I have been building a virtual MetaHuman instructor for our gym myself, and I am stuck at one specific point — I need a specialist to take it from exactly there. Please read the full post before proposing: I am not starting from zero.

WHERE I AM (already done, on my own PC)
- I have an Unreal Engine 5.8.4 project ("MUNECABEAST") on my Windows PC (i9-12900KF, 32 GB RAM, RTX 3080 Ti, 2 TB SSD).
- MetaHuman Creator plugin + full Optional Content installed (all official presets available).
- My character already exists in the project as a MetaHuman Character asset ("Rubi") — identity created and saved.
- Her "brain" (dialogues, functions, gym data) is already written on my side — that is NOT part of your work.

WHERE I AM STUCK (the exact blocker)
- In this project, the MetaHuman Character will not build. Through the MetaHuman Creator subsystem (Python API), can_build_meta_human returns False and assemble_for_preview returns None — before and after adding the character to an editing session — both in a headless commandlet AND in the full GUI editor left open ~48 minutes to settle.
- The same happens with a clean duplicate of an official preset (Ada), so it is not my character's data — it looks project/environment-level.
- Result: the build never runs and no skeletal mesh, body or face assets are ever generated. The project still contains only the 2 character assets.
- I cannot get past this point, which is why I am looking for a specialist.

WHAT I NEED FROM YOU
1) First, diagnose why this project/environment refuses to build MetaHumans and get my existing character "Rubi" to build properly in MY project, on MY PC. If you prefer to rebuild the character cleanly inside my project instead, that is fine too — what matters is a built, working MetaHuman in my project that I own and can keep adapting.
2) Then complete the rest of the scope:
- ROUTINE LIBRARY: she performs fitness routines retargeted from plain videos I supply (spinning, functional training, mini-trampoline jump, no-contact shadow boxing, and dance fitness), with a repeatable pipeline so a new video becomes a new routine.
- PRESENTER / ANNOUNCEMENT MODE (very important for us): I type an announcement text and she speaks it on camera with accurate lip sync — Spanish first, some English — and the result can be exported as an MP4 video file for Instagram ads and our gym screens.
- VOICE AND PHRASES: Spanish-first local TTS voice. She greets gym members BY NAME from a list I provide, with phrases I can update and train later without a programmer.
- She must run LOCALLY and OFFLINE on my PC. No monthly subscriptions and no cloud dependency for daily use — one-time payment only.
- Please also confirm whether these are included or priced separately: mirror mode / form correction using our Azure Kinect DK sensor (we already own it), and triggering routines from our system via simple OSC/JSON events.
3) FULL OWNERSHIP — NON-NEGOTIABLE: complete Unreal project source files, all accounts/licenses in my name (THE BEAST GYM), and a recorded step-by-step tutorial showing how I add a new routine from a plain instructor video and update playlists and voice phrases without needing a programmer. No black boxes, nothing locked to your accounts.

MY QUESTIONS (answer them in your proposal)
1. How much do you charge to take it FROM THIS EXACT POINT — first fix the build blocker in my existing project, then complete the scope above? Give me your fixed TOTAL price for starting here, not from zero. My total budget cap is USD 1,000, one-time.
2. What is the delivery time?
3. What exactly do you need from me to start (logo files, routine videos, sample announcement texts)?

Before I fund anything, I need two things in writing here on Upwork:
- An ITEMIZED LIST of everything your price includes — feature by feature — and a separate list of what is NOT included or costs extra.
- Your written confirmation that after delivery I can keep adapting her myself (add new routines from videos, new announcement texts, new greeting phrases) without hiring you again, using only the tutorial and tools you deliver. If any of my uses above is NOT covered, say so plainly in your list.

I will only fund the escrow after the full scope and the fixed price are confirmed in writing here on Upwork.

Thank you,
Ernesto Jimenez — THE BEAST GYM, Lawrence, MA, USA
