My Process 💪
Step 1 — Free brief + audit. Send your idea, prototype, Figma files, or existing codebase. As a React Native Developer and Full Stack Developer, I review architecture, scope, risk, and feasibility across mobile and web — no charge, no obligation. Most audits turn around within 24–48 hours.
Step 2 — AI-powered prototype. Using Claude Code, Cursor, and OpenAI/Gemini integrations, I build a working, testable React Native or React Next.js prototype in 3–7 days, not months — so you validate real demand before committing to full development. This is the same AI-driven approach that's cut manual workflows by 30–50% and shaved 30–40% off time-to-market on past projects.
Step 3 — Build. Full-stack build across React Native Mobile, React Native Expo, React Native Firebase, and web (React, Next.js, Node.js, Supabase/PostgreSQL, MongoDB), with weekly demos so you always know exactly what's shipped and what's next. Sprints run in 1–2 week cycles with clear, measurable milestones — the structure behind 100+ delivered projects and 60+ full production launches.
Step 4 — Launch + scale. Deployment (AWS, Google Cloud, or Azure), CI/CD, monitoring, and post-launch optimization — the same DevOps React Native process that's taken apps from 0 to 100K+ MAU, 99.9% uptime, and 5M+ requests/month, while cutting infra overhead by 35% and backend costs by 60%.
As a full-stack React Native Developer with 20,000+ hours of hands-on experience across mobile and web platforms, I specialize in React Native, Flutter, React.js, React Native Mobile, React Native Expo, React Native Firebase, React Native WebRTC to build mobile apps.

I help founders, startups, and growing businesses build reliable AI-enabled SaaS products, automation workflows, CRMs, marketplaces, and custom business platforms.
I’m Shivam, a Top Rated senior software engineer and technical lead with 16+ years of experience, $200K+ earned on Upwork, and 18,000+ hours delivered across production software projects.
My strength is not just writing code. I understand product flow, backend logic, data movement, user roles, integrations, edge cases, and the business process behind the software. That matters because most AI and SaaS projects fail for practical reasons: unclear workflows, weak architecture, poor data handling, unreliable integrations, or features that work in demo but break in real use.
I can help with:
- AI workflow automation using OpenAI, Claude, GPT, n8n, Make, and custom APIs
- Python and FastAPI backend development
- React dashboards, portals, admin panels, and internal tools
- SaaS MVP development from idea to production
- CRM, marketplace, and business workflow platforms
- API integrations, database design, and backend architecture
- Existing product improvement, rescue, modernization, and performance fixes
- RAG systems, AI assistants, document workflows, and AI-enabled reporting
I have worked across Python, Node.js, React, PHP, Ruby on Rails, databases, APIs, and cloud-based systems. I’m comfortable joining early-stage product discussions, reviewing architecture, clarifying scope, and then building the right technical foundation.
Clients usually work with me when they need someone who can think beyond tickets, communicate clearly, and take ownership of the technical direction.
A few relevant areas I can support:
- AI lead qualification and follow-up automation
- AI assistants connected to business data
- SaaS MVPs with secure backend and clean frontend
- CRM and workflow automation
- API-heavy dashboards and internal tools
- Legacy system modernization
- Complex backend logic and scalable architecture
My approach is simple: understand the business problem first, design the right technical flow, then build something practical, maintainable, and useful in the real world.
