Junaid Ahmed

Available now for full-time roles and freelance projects, remote, hybrid or on site.

I build web software that businesses rely on every day, and connect it to the rest of their systems.

Senior full-stack engineer with 9+ years in TypeScript, Angular and Node.js. Most recently a safety-critical railway maintenance platform, and LLM features where a human makes the final call.

Services

What I can help with

  • Web applications

    New builds, Angular upgrades, and cleanup of slow or tangled codebases.

  • Integrations

    REST APIs, webhooks and OAuth, keeping data in sync between systems.

  • Automation

    Replacing manual steps and spreadsheets with scheduled jobs and small internal tools.

  • LLM features that stay reliable

    Grounded answers, output validation, evaluations and human review.

Selected work

Built and shipped

Personal project, 2026

Campaign Trust and Safety Triage Copilot

An LLM-assisted review workflow for crowdfunding campaign moderation. The model recommends, a human decides.

  • Six-stage pipeline: code owns anything with a checkable answer, one LLM call handles narrative interpretation, people own every final action.
  • Every cited policy clause is validated against two registries; a citation quoting text that is not in the submission is discarded.
  • Hand-labelled evaluation set of 51 cases with a 90% agreement bar and zero tolerance for missed sanctions-list hits.

Sternico GmbH, 2023 to 2026

Railway maintenance platform

A large Angular and TypeScript application where a wrong state transition had operational consequences.

  • Interactive 3D views in BabylonJS built from scratch, with live data bound from Angular into the scene.
  • Kept the scene fast as models grew: instancing, mesh disposal, fewer redraws and frozen static geometry.
  • Moved the team from RxJS-only state to Angular Signals step by step, 25 to 30% of the codebase without a big-bang rewrite.
  • Integrated AI features and cut dashboard load times by 60%.

FiveRivers Technologies, 2019 to 2021

Micro-frontend architecture

Moved an NLP analytics product to micro frontends without stopping delivery.

  • Adopted Module Federation and led a major Angular upgrade alongside it, tripling release cadence.
  • Raised unit test coverage to 80%, cutting regressions by 60%.
