I have been building web apps and AI tools for 5+ years. I work with remote teams in Australia, US, and Pakistan. Here is what I have done. Voice AI Platform Built a voice AI tool that does pre screening interviews. It calls candidates, asks them questions, scores their answers, and gives back transcripts. I built the resume parser and ranking system too. Set up CI/CD with GitHub Actions and Docker. Runs on Cloud Run. Done 500+ automated interviews so far. No Code API Mock Tool Made a no code API mock tool for frontend devs. Built the whole thing from backend to frontend to API architecture. It pumps out 500+ APIs a month. Enterprise SaaS Apps Worked on big enterprise apps like scheduling, time tracking, background checks, and team permissions. Built UIs in Angular and React. Hooked up Rapid ID and Certn for background checks. Managed roles and permissions for 10+ teams. Made the system 25% faster by cleaning up the code. Real Time Collaboration Built a real time collaboration feature like Google Docs. 100+ users at the same time. Also made a folder system that made things 300% more organized. One feature I worked on got 20% more user engagement. Backend and Infrastructure On the backend I use Django, FastAPI, Node.js, Express, and Go. I build APIs, hook up databases, and make things work at scale. I deploy on AWS and GCP.
