Vadodara, India - 10:44 pm local time
AI SaaS developer and automation engineer building AI-powered platforms, Flutter mobile apps, and workflow automation systems that help startups operate at 3Ă— their current capacity, without 3Ă— the headcount.

My clients have raised $15M+, shipped apps with 10M+ downloads, and cut operational overhead by 40–70% after going live. Top 1% on Upwork. 30+ projects delivered. Zero open disputes.

What I build:

→ AI agents and OpenAI/LangChain workflow integrations: Replacing repetitive manual tasks with intelligent automation pipelines that make decisions, trigger actions, and escalate exceptions without human input.

→ SaaS platforms, full-stack and production-ready: React, Node.js, Firebase, Supabase, architected to scale from 100 users to 100,000 without rewrites.

→ Flutter mobile apps (iOS and Android): Cross-platform development with real-time Firebase backends, Stripe payments, and App Store deployment handled end to end.

→ Custom admin dashboards, internal tools, and CRMs that replace spreadsheets: Built around how your team actually works.

→ MVP development for founders: From idea to working product to App Store in weeks, not months.

How I work:

Every project starts with a short architecture session before a line of code is written. Founders who have worked with developers who just start building know why this matters: scope clarity upfront saves 3–6 weeks of refactoring. You get weekly progress updates, async-friendly communication, and a system clean enough to hand to any developer after delivery.

Recent results:

$15M+ raised by clients using systems I built · 10M+ app downloads · 30+ projects delivered with zero open disputes on Upwork.

Stack:

OpenAI · GPT-4o · Claude API · LangChain · RAG pipelines · LLM agents · Flutter · React.js · Next.js · Node.js · NestJS · Firebase · Supabase · PostgreSQL · AWS · Docker · Stripe · WebRTC · Socketio · Twilio · RevenueCat
