**FULL TIME 40+ HOURS A WEEK, NEW YORK TIME ZONE, USA HOURS, 830 AM TO 5 PM EST**
CLAUDE CODE MAX REQUIRED:
We are hiring a full-time Frontend Performance & Reliability Engineer to take ownership of the speed, reliability, and technical quality of AutoBuffy
⚠️ TWO NON-NEGOTIABLE REQUIREMENTS
1. WORKING HOURS: 8:30 AM–5:00 PM NEW YORK TIME
You must be online, available, and actively working during 8:30 AM–5:00 PM New York time (Eastern Time), Monday–Friday.
There are no exceptions to this schedule.
Please do not apply if you cannot consistently work these hours.
2. CLAUDE CODE MUST BE YOUR PRIMARY DEVELOPMENT TOOL
We are specifically looking for an engineer who uses Claude Code extensively every day.
We are NOT looking for someone who occasionally uses Claude, ChatGPT, Cursor, or AI autocomplete.
You should already know how to use Claude Code deeply for:
Understanding large codebases
Planning implementations
Debugging and root-cause analysis
Writing and refactoring code
Creating and managing CLAUDE.md
Skills, commands, hooks, and sub-agents
MCP integrations
Automated testing
Playwright/browser testing
Code review
Git/GitHub workflows
QA and verification loops
Documentation and maintaining project context
If Claude Code is not already central to how you engineer software, please do not apply.
Your Mission
Your job is straightforward:
Make AutoBuffy extremely fast, reliable, observable, and technically clean — every day.
This is not a general feature-development position.
You will be the engineer responsible for continuously finding and fixing performance problems, frontend errors, regressions, technical SEO issues, browser problems, and customer-facing bugs.
We want you finding problems before our customers or CEO finds them.
What You Will Own
Next.js / React frontend performance
Core Web Vitals — LCP, INP, CLS
PageSpeed Insights / Lighthouse
Chrome DevTools profiling
JavaScript and browser errors
Sentry monitoring and investigation
Mobile and cross-browser reliability
PDP, search, category, cart and checkout performance
API/network waterfall analysis
Next.js App Router performance
SSR / ISR / caching behavior
JavaScript bundle optimization
Image and asset optimization
Cloudflare / CloudFront performance
Performance regression detection
Automated browser testing
Critical customer-journey monitoring
Breadcrumbs, structured data and technical SEO
Proactively identifying technical problems
Our Stack
Monitoring: Sentry, GA4, Microsoft Clarity, Cloudflare RUM
Payments: Stripe, PayPal, Apple Pay
----
How We Work
We move quickly, but evidence matters more than assumptions.
If you say something is fixed, we expect you to prove it.
A strong update looks like:
“I reproduced the issue, traced the root cause, implemented the fix, ran automated tests and browser QA, and here are the before/after production results.”
Not:
“Claude says it's fixed.”
Claude Code should dramatically increase your output, but you remain responsible for understanding, testing, and verifying everything you ship.
Client's questions:
What percentage of your development work is currently done through Claude Code? Describe how you use it daily. (If Claude Code is not your primary development tool, please do not apply.)
How have you configured Claude Code on real projects? Describe your use of CLAUDE.md, sub-agents, skills/commands, hooks, MCPs, permissions, testing, and verification workflows.
A Next.js e-commerce product page intermittently stalls for 5–10 seconds. Walk us through exactly how you would diagnose the root cause and prove your fix worked.
What is the hardest Next.js / Core Web Vitals / frontend performance problem you've personally solved? What were the before-and-after metrics?
REQUIRED: Can you work Monday–Friday, 8:30 AM–5:00 PM New York time (Eastern Time) every working day? This schedule is mandatory and has no exceptions. Please answer YES or NO.

We need an expert low-code developer to build a production-ready MVP in 6–8 weeks.
WHAT YOU WILL BUILD:
A multi-tenant web application with 4 distinct user portals:
1. Super Admin: Manage all projects, users, and platform settings.
2. Investor Portal: View portfolio, track monthly yield/principal repayment, download automated ESG/Performance PDF reports.

• Automated Billing Engine: Auto-calculate monthly bill (kWh × PPA Rate), generate branded PDF invoices, and track payment status (Paid/Overdue).
• O&M Ticketing System: Issue tracking, assignment to technicians, and resolution logging with photo proof.
• Financial Waterfall Tracker: Dashboard showing incoming payments and their automated split (Investor Yield, Platform Fee, Reserve Fund).
• Role-Based Access Control (RBAC): Strict data isolation so investors only see their projects, and factory owners only see their site.
TECHNICAL REQUIREMENTS:
• Primary Platform: Bubble.io (Preferred) OR FlutterFlow + Supabase.
• Experience with REST API integrations (especially energy/solar APIs is a massive plus).
• Experience building multi-tenant SaaS applications with complex database relationships.
• PDF generation and automated email/WhatsApp notification workflows.
• Responsive design (must work flawlessly on mobile and desktop).
PROJECT DETAILS:
• Timeline: 6–8 weeks for MVP.
• Budget: $3,000 – $6,000 USD (Fixed price, based on experience and proposal).
• Payment Schedule: 30% upfront, 30% at Week 3 milestone, 30% at Week 6 milestone, 10% after 2-week UAT and bug fixing.
HOW TO APPLY (MUST INCLUDE):
1. Links to 2–3 complex, multi-tenant SaaS applications you have built on Bubble.io or FlutterFlow.
2. A brief explanation of your experience with API integrations and automated workflows.
3. Your proposed week-by-week timeline for this specific scope.
4. Your fixed-price quote.
5. Two references from previous clients.

We're building a real, working software product (a 3D configurator tool for the construction/contractor industry) and need a developer experienced with Claude Code to help build it out and eventually scale it.
This is a genuine, ongoing opportunity — not a one-off gig. As our technical needs grow, this role has real potential to expand into other projects within the organization.

Helping scale the product once we're ready to move faster
Potential for additional projects as our technical needs grow
Looking for:
Real, demonstrated experience with Claude Code (or similar AI-assisted development tools) — please share examples of what you've built
Comfortable working with React/JavaScript, backend integrations, and modern web development generally
Clear communicator — we value someone who can explain technical decisions in plain language, not just execute silently
Available for ongoing, flexible work, not just a single project
To apply: Please include specific examples of projects you've built with Claude Code, and your general availability/rate structure (hourly, project-based, or retainer — open to discussing what works).
please be fluent in both English and Spanish to communicate with our multinational team

I have had a Shopify account for quite some time and I am still unsure as to how to send myself my merchandise- other customers have purchased a pdf file from my store however nobody has yet to purchase a physical item from my shop and I was wondering if it worked smoothly for customers or what I would have to charge to ensure customers get their products in an ordleey fashion.

I have source code from a previous engineer who started the project but didn't finish it.
I’m looking for an experienced Shopify freelancer to help me upgrade my existing Shopify site. Current theme is Impulse, looking to migrate to the "Enterprise" theme.

AI CAD Engineer Wanted for 3D to 2D conversions using AI
Applied
$10 - $20
/ hr
29 days ago

We are looking for a CAD engineer with deep, practical experience using modern AI systems to generate complex 2D and 3D production drawings.
The top priority for this role is knowledge transfer. We need someone who not only masters the process but can effectively teach our team how to replicate and maintain AI-assisted workflows. The candidate must be able to document, explain, and train us on turning 3D models into production-ready 2D drawings with part numbers and full detailed BOMs.
We work in light steel frame construction for the skatepark and roller sports industry (ramps, platforms, rails, modular structures, etc.).
Primary Responsibilities
* Convert complex 3D models into complete sets of fabrication-ready 2D production/shop drawings, including accurate dimensions, annotations, unique part numbering, and structured Bills of Materials (BOM)
* Develop, document, and teach repeatable AI-assisted workflows for 3D-to-2D production detailing
* Mentor and train our internal team on current AI tools, techniques, and best practices for CAD generation, detailing, annotation, and BOM creation
* Evaluate and recommend AI tools and processes that fit our light steel frame production needs
* Produce high-quality deliverables while simultaneously building our team's capability to handle future projects independently
Key Requirements (Teaching & Knowledge Transfer is Top Priority)
* Demonstrated ability to teach and mentor others on AI-powered CAD workflows (not just deliver final outputs)
* Proven personal workflow for efficiently converting 3D models into detailed 2D production drawings + part numbering + BOM using AI systems
* Strong experience with current AI capabilities in CAD (generative design, AI detailing/automation tools, LLM-assisted scripting, automated BOM generation, etc.) and a willingness to share this knowledge transparently
* Proficiency in professional CAD software suitable for steel fabrication (SolidWorks, Inventor, Rhino + Grasshopper, Tekla, AutoCAD, or equivalent)
* Experience creating production drawings for light steel frame / welded steel structures
* Excellent communication and training skills — able to explain complex processes clearly to a team that is transitioning to AI-augmented methods
Test Project & Evaluation
Selected candidates will receive a complex 3D model typical of our projects.
Deliverables will include:
* Full set of 2D production drawings with part numbers and detailed BOM
* Comprehensive documentation of the exact workflow used (tools, steps, prompts/scripts, settings, etc.)
* A training/mentoring session (recorded if needed) explaining how to replicate the process on similar models
This test will evaluate both the quality of the output and the clarity of the teaching materials and knowledge transfer.
What We Expect from the Engagement
* Production-quality CAD files and drawings
* Detailed workflow documentation and training materials
* Hands-on mentoring sessions to upskill our team
* Ongoing support (as needed) for implementing and refining the AI CAD processes
This is a hands-on teaching and implementation role.
Candidates who can only deliver drawings without teaching the underlying AI workflows will not be considered. We are looking for a collaborator who will help us build internal capability in AI-assisted production detailing for our light steel frame projects.
Client's questions:
Which AI programs do you use and utilize in your day to day workflow? (even non CAD related)
In your opinion are there any significant breakthroughs in AI CAD modelling that you are excited about?
Do you have any training/teaching experience?
What are the major restrictions and limitations of your developed processes and AI integrations?
