Full-stack developer building apps, APIs & AI systems since 2012. Based in Surat, India — working worldwide in any client timezone.
I’m Anil Nikam, a freelance full-stack developer based in Surat, India with 14+ years of professional experience building software products.
Since 2012 I’ve partnered with startups, agencies, and established businesses to turn ideas into working products — from fintech applications handling secure transactions, to IoT platforms running in real time, to AI-powered tools that automate complex workflows. Whether an engagement is two weeks of backend architecture or a year of end-to-end product development, I bring the same approach: production-grade code, honest communication, and complete ownership of what I ship.
My core stack spans Flutter and Dart for cross-platform mobile apps on iOS and Android; SwiftUI and Swift for native iOS and macOS development when the project demands Apple-platform depth (system integrations, performance-critical UI, widgets, Apple Watch); Firebase for scalable serverless backends — Firestore, Cloud Functions, Realtime Database, Cloud Storage, Authentication, and FCM push notifications; Node.js and TypeScript for production-grade REST and GraphQL APIs; and modern AI integration — custom agents, prompt engineering, RAG, and LLM-powered features built on Claude, GPT, and Gemini.
50+ projects delivered with a 100% job success rate on Upwork, across fintech, social media, healthcare, e-commerce, IoT, and real-time communication platforms. I take projects end to end — architecture, database design, implementation, testing, App Store and production deployment, and long-term maintenance — so clients don’t pay handoff tax between specialists.
I work with clients worldwide and adjust my schedule to whatever timezone the project requires. Early-morning standups with European teams, late-evening launches aligned to US West Coast hours, or overlap with APAC — pick the window that works for you, and I’ll be there. If you need a freelance Flutter developer, a Firebase expert, an iOS or macOS developer with SwiftUI experience, or a full-stack engineer who can own a product from idea to App Store, I’m available for new engagements.
Flutter, Dart, SwiftUI, Swift, iOS, Android, macOS
Cross-platform apps with Flutter and Dart when you need one codebase to ship everywhere — or native iOS and macOS apps with SwiftUI and Swift when the project demands Apple-platform depth (system integrations, performance-critical UI, widgets, Apple Watch). UI, state management, platform-specific APIs, and App Store deployment handled end to end.
Node.js, TypeScript, REST, GraphQL
Scalable, secure backend systems. RESTful APIs, GraphQL endpoints, real-time WebSocket servers, microservice architectures — backends that handle growth, maintain reliability, and integrate cleanly with frontend and mobile clients.
Firestore, Cloud Functions, FCM, GCP
Six years hands-on with Firebase. Serverless backends with Cloud Functions, efficient Firestore data models, real-time sync with Realtime Database, push notifications with FCM, Cloud Storage, Authentication — all on Google Cloud Platform.
LLMs, Prompt Engineering, Claude, Gemini, ChatGPT
Intelligent features and autonomous agents built on large language models. Custom chatbots, automated workflows, prompt engineering, RAG systems — AI capabilities that deliver real value and automate complex work.
For — Startups, agencies, product teams
Cross-platform apps with Flutter and Dart that look and feel native on both iOS and Android from a single codebase. From MVPs to full-featured apps for enterprises — UI development, state management, API integration, and App Store / Play Store deployment, handled end to end.
For — Apple-first teams, premium consumer apps
Native iOS and macOS apps built with SwiftUI and Swift when cross-platform isn’t enough — Apple Watch companions, widgets, App Intents, deep system integrations, and performance-critical interfaces. App Store submission, TestFlight beta, and Mac App Store distribution included.
For — Serverless-first teams
Complete serverless backends on Firebase — Firestore database design, Cloud Functions for business logic, Firebase Authentication, Cloud Storage, FCM push notifications. Architecture that scales from day one.
For — API-first products
Production-grade REST and GraphQL APIs in Node.js and TypeScript. New from scratch, scaling an existing one, or migrating to microservices — clean, well-tested backend code your team can maintain.
For — Teams adding AI to real products
Custom chatbots, AI agents that automate workflows, RAG-based knowledge systems, and LLM-powered features with GPT, Claude, or Gemini. From prompt engineering to full agent architectures — AI made production-ready.
For — Founders and CTOs at a fork in the road
Not sure which stack? Second opinion on architecture? Consulting for mobile (Flutter or native), Firebase, and AI projects — helping teams make informed decisions on technology and strategy before code is written.
For — Solo founders, early-stage startups
From idea to App Store — architecture, database modeling, frontend and backend, third-party integrations, testing, deployment, post-launch support. One developer, complete ownership, no handoff overhead. Schedule adjusts to your timezone.
Full-stack mobile application
A complete cross-platform mobile app built in Flutter with a Firebase backend. Real-time data sync with Firestore, secure authentication, Cloud Functions for server-side logic, push notifications via FCM. Ships on iOS and Android with a smooth, native-feeling experience.
Backend architecture & development
Designed and built the entire backend infrastructure on Firebase. Architected the Firestore schema for query performance, implemented Cloud Functions for business logic, set up authentication, and configured security rules. A scalable serverless backend handling real-time sync across clients.
Backend development & consulting
Backend developer and technical consultant for this memorial platform. Built the Firebase backend from scratch, designed the data architecture, implemented Cloud Functions for automated workflows, and advised on scaling, security, and feature planning throughout.
