PORTFOLIO
Hamza Abubakar

Building resilient platforms & polished product experiences.

Senior Full Stack Engineer — 5+ years shipping production systems in Node.js, React, Next.js, and AWS.

Open to remote full-time roles, agency partnerships, and contract projects. I build scalable APIs, ship production-grade frontends, and own CI/CD end to end.

Expertise

Full Stack, Frontend, or Backend — pick the lens that fits your opening

5+ years shipping production systems end to end. Open to remote, full-time roles, agency work, and contract projects across any of these.

Full Stack Developer

End-to-end ownership from database schema to deployed UI — comfortable moving across the stack without losing velocity.

  • Production Next.js + Node.js apps
  • API design through deployment
  • Cross-functional delivery

Frontend Developer

React and Next.js interfaces that are fast, accessible, and easy to extend — App Router, server components, and performant client state.

  • React / Next.js / TypeScript
  • Design systems & component libraries
  • Core Web Vitals tuning

Backend Developer

Node.js APIs, relational and document databases, queues, and integrations that hold up under real production load.

  • REST & GraphQL APIs
  • PostgreSQL / MongoDB / Redis
  • Async jobs with Celery / queues

Cloud & DevOps

AWS infrastructure, CI/CD pipelines, and observability so releases ship safely and on a predictable cadence.

  • AWS infrastructure
  • CI/CD pipelines (GitHub Actions)
  • Monitoring & error tracking
How I work

Open to a few different kinds of engagements

Full-time, agency, or product work — I've shipped in all three and bring the same standard to each.

Full-time, remote roles

Embedded on a product or platform team, owning features end-to-end.

  • Product & platform teams
  • Long-term ownership
  • Async-friendly, any timezone

Agency & contract projects

Plugging into an agency or client team to ship a defined project fast.

  • Fixed-scope delivery
  • Client-facing communication
  • Fast ramp-up on new codebases

SaaS / product work

Hands-on with a product's roadmap — from new flows to the infra underneath them.

  • Feature delivery
  • API & data modeling
  • Monitoring & CI/CD
About

Bridging product craft & platform rigor

I lead engineering efforts that balance craft and impact—shipping resilient infrastructure while obsessing over end-user details.

  • 5+ years delivering client projects from idea to launch
  • Built scalable dashboards, APIs, and integrations for real products
  • Set up deployments and automation to ship faster and reduce bugs
  • Focus on clean code, performance, and reliable releases

Working style

  • I prioritize outcomes over output and measure success in real user impact.
  • I move fast, but I don’t ship blind — I validate early and iterate in public.
  • I keep systems clean: clear ownership, tidy interfaces, and resilient delivery.
  • I communicate crisply and surface tradeoffs so teams can decide with confidence.

ReactJS

Composable UI library powering interactive web apps.

TypeScript

Type-safe JavaScript for confident refactors and DX.

Tailwind CSS

Utility-first CSS for rapid design systems.

shadcn/ui

Composable headless components built atop Radix primitives.

Framer Motion

Production-ready animations and scroll-driven motion.

Sanity

Composable content cloud powering Editorial workflows.

Next.js

How I work

How I approach a new team or project

The same process whether it's a sprint, a contract project, or my first 90 days on a team.

Process

  1. 01

    Discovery

    Clarify goals, constraints, users, and success metrics.

  2. 02

    Plan

    Define scope, milestones, and the fastest path to launch.

  3. 03

    Build

    Ship in weekly increments with demos and clear updates.

  4. 04

    Launch

    QA, performance checks, and a smooth production rollout.

  5. 05

    Support

    Ongoing improvements, fixes, and growth experiments.

What I bring to a team

Fast ramp-up

I read code before I write code — productive within the first sprint on a new codebase.

  • Codebase deep-dives
  • Pairing early with the team
  • Shipping small wins fast

Full ownership

Comfortable owning a feature or service end-to-end, from design doc to on-call.

  • Design docs before big changes
  • API to UI to deploy
  • On-call ready

Clear communication

Async-friendly updates and tradeoffs surfaced early, not after the fact.

  • Written status updates
  • Early tradeoff discussions
  • No surprise blockers

Resolve — AI Support Ticket Agent

An AI support agent that reads a customer ticket, searches a knowledge base, and either drafts a grounded reply or escalates to a human when the docs don't cover it. Combines RAG with agentic decision-making so it never invents answers.

What I Let AI Write, and What I Never Will

After a year of Claude Code in my daily workflow, here's the honest version of how AI fits into real engineering work — the tasks I hand it without hesitation, and the ones I'll never let it own.

Recall: A RAG App That Shows Its Receipts

I built a Retrieval-Augmented Generation (RAG) app that answers questions from your documents — and shows the exact passages behind every answer, with match scores. Here's how it works and why retrieval, not the model, is the hard part.

AI Didn't Make Me Write Better Code — It Made Me Finally Write Tests

Most codebases have no tests because writing them is annoying, not because engineers can't. Here's how I used Claude Code and Cursor to go from near-zero to 70%+ coverage — without letting AI replace my judgment.
