Hire the Best Progressive Web Apps Developers in California

Full-stack developer based in San Francisco (PST). I take founders from idea to a live, production app, fast, and with senior-level execution. In the past year I've shipped 5 products end-to-end: • ChekBack - a receipt-cashback app • PhotoOffice - an AI passport-photo service • ChessTourism - a chess-tournament platform • Pluto - a field-service management system for home-service companies • MotoSocial - a social network for motorcyclists Each one went from concept to deployment, including auth, payments, integrations, and infrastructure. Why clients work with me: • US-based, real-time overlap with your business hours • Native, clear English on calls and in writing • Senior delivery - I ship working software, not just plans • I stay with you until your app is published - I never leave you alone with your issues or concerns • Warranty after delivery - if something breaks on my work, I fix it, no extra charge Core stack: React, React Native, Next.js, TypeScript, Node.js, PostgreSQL. Also: Python (FastAPI/Django), Expo, Redis, AWS/Hetzner/Cloudflare, CI/CD, REST & GraphQL, CRM and third-party integrations. Best fit for: founders and startups who need an MVP or full product built right, the first time. Send me your idea and I'll reply with a rough scope and timeline. No charge.

Hi, I’m Shaneal Prasad - a Full Stack Web & Mobile Developer with 8+ years of professional experience building scalable, high-performance applications. Over the course of my career, I’ve worked on 13+ projects, including 7 delivered independently from start to finish. I’ve partnered with 6+ companies across industries like e-commerce, finance, dentistry, and data analytics, consistently delivering reliable and efficient solutions. What sets me apart I focus on building clean, well-structured, and bug-resistant systems. In my experience, most software issues come from a lack of clarity in design and execution. My approach emphasizes understanding the problem deeply before writing code-this results in faster development, fewer bugs, and long-term maintainability. Notable experience One of my most impactful projects was taking over a failing mobile app for a dentistry company. After their senior developer spent over a year without delivering a working product, I rebuilt the application from scratch-even without prior mobile experience-and successfully delivered it in just 4 months. The final product was stable, performant, and production-ready. I’ve also built advanced systems like a stock market bot and a mobile tele-dentistry platform, demonstrating my ability to handle complex, real-world problems. How I work I take ownership of projects and deliver results I communicate clearly and make thoughtful recommendations I respect your vision while ensuring technical excellence I prioritize speed without sacrificing quality My goal is simple: deliver high-quality software that saves you time and money.

I'm a US-based developer who helps small businesses and non-technical founders turn ideas into working web applications. My approach: understand your business first—what problem you're solving, who it's for, what success looks like—then build software that actually solves that problem. I specialize in React, TypeScript, and Firebase, which lets me deliver complete applications (user authentication, database, file storage, backend logic) without the overhead and cost of traditional server infrastructure. I communicate clearly, respond promptly, and I'm in your timezone. I work best with clients who value collaboration over rushed timelines. If you're looking for a developer who listens first and codes second, let's talk.
