Full-Stack Technical Expertise
Designs and ships full-stack products covering the complete vertical: database schema (PostgreSQL with Drizzle ORM), REST/GraphQL API (Node.js with Express or Next.js API routes), frontend (React 18 + Next.js 14 with TypeScript), mobile (Flutter for iOS and Android), and deployment (Docker on AWS or Cloudflare Pages). Applies Domain-Driven Design principles to keep business logic in the service layer, away from transport (HTTP) and persistence (ORM) concerns. Uses a monorepo structure (Turborepo) for code sharing between web and mobile clients, and implements feature flags via environment-based toggles for safe production deployments.
India Market Context
India's $250B+ tech industry — the world's largest engineering talent market.

Why Hire for Full-Stack?
- True full-stack: mobile (Flutter/React Native), frontend (React/Next.js), backend (Node.js), database (PostgreSQL/MongoDB), and DevOps (Docker/AWS) — all in production.
- Built Loopin entirely solo — Flutter mobile app + Google Drive API backend + local Hive database. Product to production by one engineer.
- Built Legease solo — Flutter frontend + AI/ML API integration + PDF processing backend + cross-platform deployment.
- ESPO work: full-stack contribution across mobile (Flutter) and web platform features in a real startup team.
- Tech stack depth: 15+ technologies at production level — Flutter, React, Next.js, Node.js, PostgreSQL, Redis, Docker, AWS.
- 1.5+ years professional experience as the only engineer on multiple projects — full ownership end-to-end.
- Hackathon Finalist × 3 — all full-stack solo submissions in 24-48 hour sprint formats.
- MAIT B.Tech CST, 9.12 CGPA — systems design, algorithms, and database engineering at academic depth.

How Full-Stack Development Works
A structured, transparent process from kickoff to App Store — no black boxes.
System Design
ERD for database schema, API contract design (OpenAPI), mobile screen flow, and deployment architecture diagram before writing code.
Backend First
Database migrations, API routes, authentication, and business logic — fully tested in isolation before connecting to any client.
Web Frontend
Next.js App Router pages consuming the API, TypeScript strict throughout, Core Web Vitals targets set from day one.
Mobile App
Flutter or React Native client consuming the same API — shared TypeScript types for API contracts.
CI/CD & Monitoring
GitHub Actions pipeline running tests + type checks + linting, automated deployment to Cloudflare/Vercel + Play Store + App Store.
Full-Stack in India — What Most Devs Miss
For India-based startups with limited funding, a single full-stack engineer who owns mobile + web + backend is 3x more cost-effective than three specialists — and delivers faster because there's zero coordination overhead.
The rise of Next.js Server Components and Expo EAS means a full-stack developer in 2024 can ship a production web app and mobile app sharing the same TypeScript type layer — a technical capability that didn't exist two years ago.
Full-stack ownership creates better products — an engineer who understands the database query can design an API that doesn't require N+1 queries from the frontend, eliminating performance problems before they become production incidents.
Sachin Sharma vs. Alternatives
| Alternative | Why Sachin Sharma Instead |
|---|---|
| Large Development Agencies | Direct access to the senior Full-Stack engineer — no account managers, no relay game. What you say is what gets built. |
| Junior Freelancers | Production-verified Full-Stack codebase with real apps (22K+ downloads) — not tutorial-level work. |
| Offshore Development Factories | Deep product involvement in every Full-Stack feature — not just ticket execution, but architectural ownership. |
Proof Points
- Sole engineer on Loopin, Legease, and Aashwasan — designed, built, and shipped all three to app stores independently.
- Full deployment chain ownership: domain DNS, Cloudflare Pages edge config, Next.js build pipeline, and CI/CD via GitHub Actions.
- Cross-stack type safety: TypeScript on frontend, Zod for API contracts, Dart's sound null safety on mobile — type discipline at every layer.
- Performance end-to-end: Flutter 60fps animations, Next.js LCP < 2.5s, Node.js p95 < 200ms API latency, PostgreSQL query optimization.
- Product thinking alongside engineering: Loopin's RPG habit mechanic, Legease's AI legal UX — UX-first feature design, not just technical delivery.
