Job Success
Islamabad, Pakistan - 2:55 pm local time
Most freelancers write code. I architect the system: I plan it, build it, ship it, and stay on until it's stable in production.
🔥 I got you if you need
• LLM agents - multi-step agents that actually do work, not demo chatbots
• RAG over your private data - retrieval that returns the right chunk, evaluated not guessed
• Custom workflow automation - written as real software in your codebase
• AI features inside existing products - assistants, chat, generation, classification
• Full SaaS platforms end to end - auth, billing, dashboards, integrations
• Third-party and API integrations, including HL7/FHIR for healthcare data exchange
🔥 Code Level Automations
I build automation as software you own, in your repo, under version control and tests. If you're looking for someone to wire up n8n, Make or Zapier, I'm not the right fit - and I'll tell you that on the first call rather than take the job.
🎖️ Track record

👀 Project Navigation
1. Scope: I map your goals, users and core requirements, and give you an honest read on feasibility before you spend anything.
2. Architecture: clear system design, milestones and a roadmap agreed before development starts.
3. Build: short cycles with visible progress and working features you can use, not status reports.
4. Ship: thorough testing, stable delivery, and 30 days of post-launch support.
