Smith Gajjar - Senior Software Engineer

01

About

Building software systems for 5+ years, focused on making applications run smoothly and scale reliably. Currently shipping agentic AI learning systems and managing platform architecture at Codecademy (Skillsoft). Previously a founding engineer at Tekie.

Every now and then I build something on the side. Small experiments, tools that somehow become useful, and projects that teach me more than I expected.
