Full-Stack AI Engineer · Lahore · available for freelance
I build & ship whole products. Solo, end to end.
Email deliverability infrastructure, AI agents, and full-stack apps. Ask my AI anything about how I work, or book a call.
Selected work
Shipped products, not demos
I build the parts other people find hard.
Whole products
Idea to shipped, solo
I take products from an empty repo to deployed and maintained: frontend, backend, infra, the lot. Two of my SaaS products I built and run entirely on my own.
AI & agents
Agents that actually do things
RAG systems, LangGraph / LangChain agents, and the MCP servers and connectors that let AI take real actions. This site's chatbot is one of them.
Email infrastructure
Deliverability, done right
DMARC / DKIM / SPF, inbox warmup, sending pipelines, and verification at scale. The unglamorous, hard part of email that most people get subtly wrong.
Full-stack & mobile
Apps that stay up
Next.js, Rails, React Native — real-time features, payments, dashboards, and the reliability work that keeps them running after launch.
A calm, predictable way to work together.
Discovery call
We talk through the problem, the scope, and whether I'm the right fit. Free, 20 minutes, no pressure.
Scope & plan
I turn it into a concrete plan: milestones, a fixed shape, and a clear price, so you know exactly what you're getting.
Build in the open
You see progress continuously: deployed previews, not status reports. Tight feedback loops, no surprises at the end.
Ship & maintain
I don't disappear at launch. Monitoring, fixes, and the next iteration. I treat it like my own product.
~3 years, idea to production.
Intern → Associate → Software Engineer
Took SaaS products from idea to production with the team, owning delivery across frontend, backend, and deployment, and I'm working the same way on a cold-outreach platform currently in development. On emailverify.io I built the email-sending microservice, AWS Lambda crons, a layered security architecture for the public APIs, deliverability tooling, and the whole integration ecosystem (n8n node, WordPress plugin, MCP server, CRM/ESP connectors).
B.S. Computer Science
CGPA 3.81 / 4.0. Silver Medalist, SP22 batch. Built my flagship AI and full-stack projects alongside my degree.
WordPress Developer
Built responsive WordPress sites from scratch, fixed bugs, and optimized performance with plugins and themes.
Software Engineer Intern
Built websites with HTML/CSS and web apps with ASP.NET (C#); delivered an internal time-management tool for the HR team.
The stack I reach for.
Not a checklist. These are the tools behind the shipped products above. I pick the right one for the job, not the trendy one.

Email deliverability
AI-assisted dev
I like the hard, unglamorous parts.
I'm Shafin Zaman, a Full-Stack AI Engineer based in Lahore. I'm drawn to the parts most people avoid: email deliverability, the plumbing AI agents run on, and the reliability work that makes a product actually usable rather than just a demo.
I've shipped an AI healthcare platform, live email-infrastructure SaaS, a real-time estate super-app, and more, often as the only engineer, from the first commit to production and beyond. I care about shipping things that hold up, and about being straight with the people I build for.
Right now I'm available for freelance work.If you've got something hard, I'd like to hear about it.
Answers, before you ask.
Or just ask my AI anything above. It knows all of this and more.
Is Shafin available for freelance work?
Yes. I'm currently available for freelance projects. The best first step is a free 20-minute discovery call so we can see if it's a fit.
What does Shafin specialize in?
Two things most developers don't: email deliverability infrastructure (warmup, DMARC/DKIM/SPF, sending pipelines) and AI agents (RAG, LangGraph/LangChain, MCP servers). Alongside general full-stack web and mobile work. I ship whole products solo, from the first commit to production.
Does Shafin do email deliverability (DMARC, DKIM, SPF, warmup)?
Yes, it's one of my core specialities. I've worked end to end on email deliverability products, and built the sending microservice, deliverability tooling, and integration ecosystem for emailverify.io.
Can Shafin build AI agents, RAG systems, or MCP servers?
Yes. I built TabeebAI (agentic symptom triage with RAG), the grounded AI assistant that runs this very site, and MCP servers and connectors that let AI take real actions. This portfolio even ships as an MCP server.
What's Shafin's tech stack?
Front end: Next.js, React, React Native, Tailwind. Back end: Node.js, Nest.js, Ruby on Rails, Django, FastAPI. Data: PostgreSQL, MongoDB, Redis. AI: LangGraph, LangChain, RAG, MCP, vector search. Cloud: AWS, Azure, Docker, CI/CD.
Where is Shafin based, and does he work remotely?
I'm based in Lahore, Pakistan, and work with clients remotely.
This site is also an MCP server.
Add it to Claude, Cursor, or any MCP client and ask your own AI about my work. It queries this portfolio directly, grounded in the real projects. Building the tools agents run on is a lot of what I do, so it felt right to ship one.
