Fasih Ullah SaleemFull-Stack Developer

Full-Stack Developer | React | FastAPI | Python

I build responsive, interactive web applications with React on the frontend and Python (FastAPI/Django) with PostgreSQL on the backend. I designed and shipped twelve live, production-quality websites featuring 3D rendering (react-three-fiber), scroll-driven SVG animation and GPU-accelerated effects, see them on the work page. I own features end to end: UI/UX, REST APIs, databases and deployment (Docker, Nginx, Linux), in remote, international teams.

In the stack

Where a full-stack developer sits in a connected product.

The solid layers are the ones this role owns: cloud & backend, web & app. The faded ones are the rest of the system I also build, so nothing is designed in isolation.

Hire me for

Three things I can start on next week.

For a team, a startup, a research group or one person with an idea. Remote, worldwide, and I reply within a day.

  1. 01

    A complete website or web app for your business, practice or product, design system, build and deployment.

  2. 02

    A React frontend on your existing API, or a FastAPI backend under your existing frontend.

  3. 03

    Signature interactions: 3D, scroll-driven and canvas work that most agencies quote as impossible.

Relevant projects

Full-Stack work, built and photographed on my own bench.

Each card opens the full story: what it does, how it was built and which layers of the stack I built myself.

  • Custom four-layer PCB for the fleet tracker on a cutting mat, with GPS patch antenna, GSM module and screw terminals

    Lead: firmware, PCB and integration

    An end-to-end fleet telematics system built on a custom STM32F427 board. The device reads GPS position and MPU6050 motion data in real time, detects accidents and rollovers, and streams everything over a SIM800L GSM link to a web dashboard. A full power subsystem handles automatic switching between the vehicle battery and an onboard backup, with charging and protection circuitry, so the unit stays online even if main power is cut.

    Embedded + cloud pipeline

    An IoT data pipeline that takes readings from embedded sensor nodes and publishes them over MQTT to a cloud database, where they feed into monitoring applications. The project demonstrates the full telemetry loop: device acquisition, lightweight pub/sub transport, persistence, and live visualization.

    Research & prototyping

    A local-first AI assistant built on open-source LLMs running entirely on-device. I explored Retrieval-Augmented Generation and vector-database concepts to ground the model in a private knowledge base, then experimented with prompt engineering, conversational interfaces, and agent workflows, evaluating model quality, hardware requirements, and deployment trade-offs along the way.

Questions

What people ask before hiring a full-stack developer.

Can I see websites you have built before hiring you?

Yes, twelve complete, live sites are on the work page, each for a different business or profession, each with its own design system and signature interaction. They are production sites, not mockups.

Do you build 3D or animated websites?

Yes. Several of the live sites use react-three-fiber for real 3D models, scroll-driven SVG animation and GPU-only effects, and this portfolio itself renders a procedural 3D model in the hero. Motion is always measured against Core Web Vitals, never added for its own sake.

What does a typical website project cost and how long does it take?

Most business or professional sites ship within a couple of weeks. Cost depends on scope, content, photography, 3D, integrations, so I quote per project after a short intake call. Email me with what the site is for and who it is for.

Do you work with international clients remotely?

Open to remote and on-site roles worldwide, and freelance web projects for clients anywhere. I am based in Pakistan; every one of the twelve live sites was designed, built and deployed remotely.

Also hire me as

The same engineer, seen from other angles.

One person, nine job titles. Each page argues the case from that field's side, with the projects that prove it.
