Summary

Senior engineer with 9+ years building production web applications that businesses use every day, mostly in Angular and TypeScript, with backend work in Node.js/Express and Python/Django. I connect systems through REST APIs, webhooks and OAuth flows, and I build LLM workflows where deterministic code, the model and a human reviewer each own a clear part of the decision. I use Cursor and Claude Code daily, work independently in remote, distributed teams, and am available to start immediately, for full-time roles or freelance projects.

Applied AI project

Campaign Trust and Safety Triage Copilot (personal project, 2026)

Live demo: triage-copilot.junaidahmed.dev

  • Built an LLM-assisted review workflow for a crowdfunding platform's campaign moderation process, where the model recommends but never decides; every action needs human sign-off with a documented reason
  • Designed a six-stage pipeline that splits responsibility explicitly: deterministic code owns anything with a checkable answer, one LLM call handles narrative interpretation, and humans own every final action
  • Enforced citation-grounded output: model-cited policy clauses are validated against two clause registries, and any citation quoting text not present in the source submission is discarded
  • Built a hand-labeled evaluation set (51 cases, 34 tuning and 17 held-out) with a 90% agreement threshold and zero tolerance for missed sanctions-list hits before any change ships
  • Used OpenRouter for a model-agnostic architecture, allowing cost and quality trade-offs across providers

Other projects

World Cup 2026 Calendar (personal project, 2026)

  • Built a Python scraper (requests, BeautifulSoup4) running on a scheduled GitHub Actions workflow that pulls FIFA World Cup 2026 bracket data and publishes it as an ICS calendar file

Experience

Senior Frontend Developer, Sternico GmbH

09/2023 to 05/2026 · Wendeburg, Germany

  • Worked on a large Angular and TypeScript application for a safety-critical railway maintenance platform, where a wrong state transition had operational consequences
  • Led an incremental move from RxJS-only state to Angular Signals: any code the team touched or wrote moved to Signals, bringing 25 to 30% of the codebase over without a big-bang rewrite
  • Organized the frontend in an Nx workspace with shared libraries
  • Integrated AI features into the product
  • Built interactive 3D views in BabylonJS from scratch: custom shapes composed into connected assemblies, drag and click interaction, and live binding of application data from Angular into the scene
  • Optimized 3D scene performance as models grew: instanced repeated geometry, disposed unused meshes, cut unnecessary redraws, and froze static parts of the scene, unfreezing only to apply changes
  • Cut dashboard load times by 60% through data-fetching and rendering optimization
  • Raised code quality through testing standards, code review and mentoring

Senior Web and Mobile Application Developer, DeinePflege GmbH

11/2022 to 07/2023 · Konstanz, Germany (remote)

  • Led development of modular dashboards for real-time operations
  • Reduced technical debt by 50% and cut build times by 35%
  • Improved reliability and data synchronization for live metrics

Senior Frontend Developer, DP World

05/2022 to 10/2022 · Dubai, UAE (remote)

  • Restored 24/7 reliability for port operations metrics by resolving real-time data sync issues
  • Architected a monorepo, reducing build times by 35%
  • Modernized dashboard interfaces to enterprise-grade usability and reduced technical debt by 50% through modularization and deprecated-code audits

Senior Frontend Developer, Strategic Systems International (SSI)

07/2021 to 05/2022 · Lahore, Pakistan

  • Owned design and delivery of dispatch and scheduling UIs for a German transportation management SaaS, turning Figma designs into reusable Angular modules
  • Cut dashboard render times by 70% by reworking ag-Grid rendering logic
  • Wrote custom ESLint rules and led code reviews, reducing post-deployment bugs by 30%
