Project details
Built your MVP with Lovable but stuck with errors, broken features, or integrations that don't scale? You're not alone.
I'll help you transform it into a production-ready app that's stable, secure, and investor-ready.
What this includes:
• fix auth bugs (login, signup, password reset)
• fix Stripe payment issues (checkout, webhooks, subscriptions)
• optimize Supabase queries and database structure
• fix broken API integrations
• set up proper error handling and logging
• deploy to Vercel, Supabase, or your preferred host
I've shipped 50+ apps on Next.js + Supabase + Stripe. I know exactly where Lovable and Bolt prototypes break and how to fix them fast.
This isn't a band-aid. I rebuild the weak parts so your app works properly in production with real users.

Job Success
Peshawar, Pakistan - 6:40 am local time
Background: MSc in Electrical Engineering (University Gold Medalist), published researcher in deep learning, ex-Pakistan Air Force R&D engineer (computer vision + satellite image recognition), former CTO at a UK SaaS company (Atarim) for 4 years, and 43 machine learning projects delivered on Fiverr before I moved to Upwork full-time. I also consulted for Pensa Systems (Austin, TX), building multi-agent AI systems with LangGraph, RAG, and GPT-4o deployed on AWS EKS.
I've been writing code professionally since 2015 and building AI systems since before ChatGPT existed.
Today, I run Tech Emulsion, a 30+ person engineering team. I'm your main point of contact on every project. You talk to me on calls, I make the architecture decisions, and I'll tell you when something is a bad idea before you spend money on it. Behind me is a full team of engineers, QA, DevOps, and project management with mature engineering practices: code reviews, automated testing, CI/CD pipelines, and AI-assisted quality checks baked into every sprint.
Here's what I build every day:
AI AGENTS & CHATBOTS
I build custom AI agents, chatbots, and RAG systems trained on your data. I've built AI voice agents using Retell and Vapi that answer inbound calls, qualify leads, and book appointments into CRMs. I've built Retrieval-Augmented Generation pipelines that turn 200-page technical manuals into instant answers. I've built GPT-powered chatbots integrated with Shopify that handle 80% of customer support questions without a human.
Stack: Claude API, OpenAI API, GPT-4, LangChain, LangGraph, Pinecone, ChromaDB, Retell, Vapi, ElevenLabs, Supabase, n8n.
WORKFLOW AUTOMATION & AI INTEGRATION
I connect your tools so that data flows without manual work. Lead routing, follow-up sequences, CRM logging, document processing, notifications, all automated end-to-end. I work with n8n, Make, Zapier, and custom API integrations. One client went from 4 hours/day of manual data entry to zero.
AI CONSULTING & CLAUDE IMPLEMENTATION
I help businesses figure out where AI actually fits in their operations and then build it. I work with Claude (Anthropic's API, Claude Code, Claude Cowork) to automate workflows that used to require entire teams: document processing, report generation, code reviews, data extraction, content pipelines, and internal knowledge bases. If you're sitting on repetitive business processes and wondering how to use AI to cut 20+ hours/week, that's exactly what I consult on. I scope the opportunity, design the system, and my team builds it.
FULL-STACK SAAS & WEB APPLICATIONS
I build production-grade SaaS platforms from zero to launch in 4-8 weeks. Dashboards, auth, payments, admin panels, real-time features, API integrations. Next.js, React, Supabase, FastAPI, Node.js, PostgreSQL, Stripe. I've built field service management platforms, LinkedIn prospecting tools, nutrition tracking apps, billboard management dashboards, and AI-powered sales trainers.
LOVABLE, REPLIT & BOLT RESCUE
Clients come to me with broken Lovable and Bolt prototypes that look good but don't actually work: auth failures, broken Supabase connections, no real backend logic, and payment integration issues. I either fix them inside Lovable or rebuild them properly on Next.js + Supabase + FastAPI. I've productionized Lovable prototypes for field service management, telecom operations, and out-of-home advertising platforms.
MOBILE APP DEVELOPMENT
React Native apps with AI features: nutrition tracking, calorie counting, VPN clients, fitness apps. Full App Store deployment on iOS and Android.
CHROME EXTENSIONS & WEB AUTOMATION
I've built browser extensions for WhatsApp automation, YouTube mood-based search, LinkedIn content analysis, and visual feedback tools. Also built data scraping and web automation systems.

Certifications: IELTS (English Proficiency), React Nanodegree, Machine Learning (Stanford/Coursera), Deep Learning Specialization (DeepLearning).
