About Me
Vishwajeet Kumar
Software engineer with ~2 years of experience across full-stack, backend systems, and AI/ML integration. I've worked at a logistics startup, an edtech fintech, and done freelance work — mostly building things from scratch or scaling things that were already in production. I like working across the whole stack but I'm most comfortable in backend and systems work.
