Full Stack Web Development, Need Pakistani Programmers
About Zaffar
Full-stack & AI Integration Dev |Next.js, Supabase, Golang, Claude API
Gilgit, Pakistan - 6:55 am local time
My core stack is Next.js, TypeScript, Supabase, and PostgreSQL on the product side. On the AI side I work with the Claude API and OpenAI to build things that hold up in real usage: RAG pipelines that retrieve from your actual data, AI agents that trigger real actions through tool calling, document processing systems, and conversational features embedded inside working SaaS products. For backend services that need real throughput I write in Golang. When teams have outgrown Node.js or need microservices that do not fall over under load, that is the part of the work I actually enjoy.
The most recent role on my profile is Senior AI Integration Expert at Proposala, where I built the AI layer for a B2B proposal automation platform. The core problem: sales teams were spending 45 to 60 minutes per proposal pulling product details, pricing, and compliance language by hand. I integrated Claude API to generate structured first-draft proposals from a short input, with output that mapped directly into their existing template format. Proposal generation time dropped to under eight minutes. That is the kind of problem I am good at: not adding AI for the sake of it, but finding the one place in a workflow where it cuts real time.
Before Proposala I spent five years as a Senior Full-Stack Engineer on Upwork, building products for clients across industries in React, Vue, Node.js, and PostgreSQL. Before that three years at uConnect building enterprise SaaS interfaces: a cloud cost management portal, a banking and HR platform, and a point-of-sale system. The full-stack side is not something I picked up to support AI work. It is the majority of my career.
What working with me looks like in practice: you give me a brief or a Figma file, I ask the questions that actually matter for scope, I give you a timeline that does not shift, and I ship. I document the code properly. If something breaks after handover I am reachable.
I work best on projects where one person needs to cover the whole product. Send me a message with what you are building and I will tell you within a few hours whether I can help and what the scope looks like.
