Offline-First Field Service App
Offline-first field service platform with a React Native app for technicians and a browser-based control panel for dispatch, scheduling, and job oversight.
Delivered a React Native workflow for dispatch, route planning, photo capture, signatures, and sync in low-connectivity environments, backed by a web console for operators.

“This was the first mobile tool our technicians did not fight in the field.”
Alicia P.
Operations Director
The Challenge
The client was coordinating field teams through spreadsheets, calls, and a brittle legacy app that failed in low-connectivity environments. Technicians lost data in the field, and managers had poor visibility into job progress.
The Solution
I rebuilt the mobile workflow around offline reliability: local-first job state, background sync, route-aware scheduling, media capture, signatures, and a web control panel for dispatchers. The result was a tool the field team could use reliably on real job sites.

Project Details
Technical implementation and architecture overview
Offline-first job execution
Designed the app so technicians could open jobs, capture progress, attach photos, and collect signatures without needing live connectivity at every step.
Dispatch and route coordination
Built the browser console for assigning work, viewing technician status, and adjusting schedules as field conditions changed throughout the day.
Media, sync, and auditability
Background sync, retry-safe uploads, and job-history tracking gave the operations team a reliable record of what happened on site and when.
FAQs
How much does it cost? +
Complete projects start at $2,000. I give you a fixed price after a free 30-minute call — no hourly billing, no surprise invoices.
How fast can you deliver? +
Most MVPs go live in 2–4 weeks. Larger projects run in 2-week sprints with a live demo every week so you always see progress.
Who will actually build my product? +
Me. Personally. I have 10+ years of experience and I handle everything — frontend, backend, infrastructure, deployment. No outsourcing.
What makes you different from agencies? +
No overhead. You talk directly to me — the person writing the code. That means faster decisions, better output, and lower cost.
What if I need changes after launch? +
You get 30 days of free post-launch support included. After that, I offer affordable monthly retainers or project-based work.
What technologies do you use? +
TypeScript, React, FastAPI, Node.js, Python, Rust, Solidity, React Native, Flutter — I pick what fits your project, not what's trendy.
Can one person really handle everything? +
Yes. Frontend, backend, infrastructure, mobile, and Web3. With 10+ years of experience and AI-accelerated workflows, I consistently deliver what agencies need 10 people to build.
Do you use AI to write code? +
Yes. I use AI as a force multiplier — for code generation, review, testing, and documentation. It's why I ship 3x faster than traditional developers. But every line is reviewed, tested, and refined by me before it touches your project.
Is your code production-ready? +
Yes. Every project I deliver is production-grade — tested, optimized, secure, and deployed to real infrastructure. I don't hand off prototypes. You get code that's ready for real users from day one.
What if my project doesn't work out? +
You own everything I build — every line of code, every design file. If you want to walk away or bring in another team, you can. No lock-in.
