Hi, I'm

Muhammad Jafar,a full-stack developer shipping calm, fast software from Germany.

I spend my days at axess Intelligence designing and building a production Next.js platform — from TypeScript components down to Postgres query plans. I care about performance, ergonomics, and the quiet kind of polish that makes software feel thought-through.

§ 01About

An engineer who cares about the whole stack — and the whole user.

I'm a full-stack developer based in Gelsenkirchen, in the Ruhrgebiet (NRW), with over three years of experience building and maintaining responsive, user-focused web applications. I work across the entire stack — from clean React interfaces to robust backend APIs and sharply optimized database layers — and I take each layer equally seriously.

Currently at axess Intelligence, I own and evolve the company's Next.js platform: shipping features, taming SQL queries on PostgreSQL and MySQL, and keeping CI/CD on Vercel humming. Before that, at Sunskill Techs in Islamabad, I led the migration of a legacy PHP system to a modern React + Node.js stack with a 45% improvement in page load times.

I care about clean code, strong problem-solving, and picking up the next tool before I'm asked to. I work well inside Agile teams and I take performance, maintainability, and craft seriously — because the only software worth shipping is the kind you'd be happy to inherit.

§ 02What I build

Three kinds of work — and I take each one seriously.

Most of what I do falls into one of these buckets. I'm happiest when all three are on the table.

01

Product web apps

End-to-end React & Next.js applications — from forms and flows to dashboards and auth. Server Actions, typed data layers, and tests that actually run before deploy.

Best fit forteams shipping their first real product, or rebuilding a legacy frontend without regressions.
02

Database & API work

SQL query tuning, index design, schema migrations, and typed ORM layers. When the backend feels slow, there's usually a query or an index that changes everything.

Best fit forCRMs, analytics platforms, any product with non-trivial Postgres or MySQL.
03

Ship ops & delivery

CI/CD pipelines, preview environments, and release workflows on Vercel and GitHub Actions. Getting code to production safely — and often enough that Friday isn't scary.

Best fit forteams that want push-to-deploy confidence, not weekend releases.
§ 03Selected work

Three years, one company obsessed over — and a prior life migrating a PHP monolith.

§ 05Principles

How I work — on a good day and a bad one.

Short enough to fit on a sticky note. Long enough to matter.

  1. 01.Speed

    Performance is a feature.

    Every millisecond your app shaves off a response is a favor to the next developer who loads it, and the next user who clicks it. I treat slowness like a bug — because it is.

  2. 02.Clarity

    Types are documentation that can't go stale.

    I reach for TypeScript because it tells the next reader what a function expects — and stops me, loudly, when I break that contract. Strictness is kindness.

  3. 03.Rhythm

    Small PRs. Short feedback loops.

    Big branches are where bugs live. I work in thin, reviewable slices, push often, and trust the test suite and the team review to catch what I'll miss.

  4. 04.Discipline

    Write it once, well.

    If you're pasting, you're deciding. I'd rather lift an abstraction at copy #2 than regret ten copies later. Most cleverness is just a careful rename away.
