Senior full stack engineer

Hi, I'm Shariq. I build fast, production-ready web apps with React, Next.js and Node.js — from AI voice agents and live avatars to Stripe-powered SaaS. I take products from the first call to launch, and stay around after.

About me

I'm a senior full stack engineer who likes owning a product end to end — talking to the client, shaping the requirements, writing the code and setting up the pipeline that ships it.

Lately that's meant leading a subscription platform to 410 active subscribers as its sole engineer, building production voice agents, and wiring OpenAI, LangChain and live avatars into real products. Before that I led a team of four on a U.S. investment platform and tuned frontends for a national restaurant chain.

You get clean, typed, tested code, clear communication and a developer who cares how fast your pages load.

My working process

A simple, transparent way to go from idea to a live product — no surprises along the way.

  1. STEP 01

    Discovery call

    We talk through your goals, users and budget. You get a clear scope and estimate.

  2. STEP 02

    Plan & architecture

    Data model, stack and milestones agreed before a line of code is written.

  3. STEP 03

    Build in the open

    Regular demos, typed and tested code, and your feedback folded in as we go.

  4. STEP 04

    Launch & support

    CI/CD, error monitoring and a smooth handover — with support after launch.
