You will get Angular frontend development with NgRx state management

Project details
State management is where Angular apps either stay predictable or turn into a debugging nightmare. I set up NgRx properly — actions, reducers, effects, and selectors structured so state changes are traceable, not scattered across components.

React App Is Slow & Crashing Under Load — Need Performance Fix & Stabilization
Usama diagnosed and fixed the performance problems in our React app that had been slowing us down for months. Page loads went from 5–8 seconds down to under 2, the dashboard freezing on large lists is completely gone, and the random production crashes have stopped. What stood out most was that he actually found the root causes instead of applying band-aids — and he documented everything so our team understands what was wrong. Communication was clear and jargon-free, updates were consistent, and he delivered on time. We've already started him on new features. Highly recommend.

Full-Stack Developer for AI-Integrated Web App
Usama did excellent work on our AI-integrated web app. Built a clean React/Next.js front-end and a solid Node back-end, and handled the OpenAI and Claude integration smoothly. Communication was clear and consistent, deadlines were met, and the quality was high throughout. Highly recommend - would hire again.
