Full Stack AI Developer
Apr 2024 - Present • 2 yrs 1 mo
Specialized into AI SaaS development. Started working with Claude API, OpenAI, and LangChain to build products like Skallix, RapidRoot, and AI agents. Today I own AI SaaS products end to end for founders. 16 live products shipped, real users, still running. No handoffs, no chaos, just clean working software.
Full Stack Developer
Jun 2023 - Jun 2024 • 1 yr
Made the jump to full stack. Picked up Python, FastAPI, Django, and PostgreSQL. Started owning entire features instead of just the frontend. Shipped products like LootEdge, Practice Tool AI, and MyGuidance, handling everything from database design to deployment. This is where I learned how to think about architecture instead of just components.
Frontend Developer
Upwork • Part-time
Dec 2021 - Jun 2023 • 1 yr 6 mos
Moved into building full web applications. Worked on React, Next.js, and TypeScript projects for clients across e-commerce, edtech, and SaaS. This was the phase where I stopped just writing code and started thinking like a developer. Learned how to read designs, work with backend teams, ship on tight deadlines, and handle real client feedback.
