Open to senior full-stack roles · Taking on select freelance projects
Jasir KFull Stack Engineer
I build the interfaces people rely on every day.
Full stack engineer, 6+ years at Uber, FactSet and Infrrd.ai. React to Go, idea to production — and with Claude and Cursor as my pair programmers, I ship at the pace of a small team.
01About
Most teams hire an engineer who ships fast or one who sweats the details. I’m both.
I started in 2019 at Infrrd.ai, building reusable UI for Homegenius, a real estate transaction platform. It taught me that a good component library is a product in its own right.
At FactSet I moved into financial tooling for portfolio managers, and learned that tests are a feature: the E2E suites I set up cut application bugs by 70%. I also moved our build from Webpack to Vite.
Then Uber. Since 2023 I’ve worked on the support platform 30,000+ agents use every day — co-owning the phone channel, leading the frontend for a new way for drivers to earn between trips, and shipping 370+ production changes along the way.
01End-to-end ownership
I write the technical design, ship it behind a feature flag, and watch the dashboards after. 25+ design docs and an on-call rotation say I finish what I start.
02Interface craft
Motion, accessibility and performance aren’t polish added at the end — they’re part of the build. This site is the proof.
03AI-assisted pace
Claude and Cursor are part of how I work every day. I write Claude Skills that automate the tedious parts of engineering, so the hard parts get my full attention.
02Experience
Selected work, 2019 – 2026
Six years shipping interfaces, at scale.
From a real estate platform to financial analytics to the support platform behind Uber — owning features from the first design doc to production.

Frameworkagnostic
React, Vue and Angular — I’ve shipped production code in all three. Components, state and accessibility are the same problems everywhere.
06How I work
You get one engineer who can own a feature end to end — design it, build it, ship it safely and keep it healthy, without the hand-offs.
01Design
A technical design doc, edge cases and a rollout plan before the first line of code.
02Build
Accessible, fast UI with the tests to back it up.
03Ship & run
Feature-flagged rollouts, observability and on-call. Same person.
07Off the clock
Behind a camera, or on the road

Building something people use every day? Let’s talk.
I’m looking for my next senior frontend or full-stack role, and I take on a few website projects for local businesses.
