Aakarsh Singh / Full-Stack & AI Engineer

I buildproductspeopleactually use.

Full-stack and AI engineer building resilient software and high-scale backends powering over 7.5 million active users.

Selected experience

Work that survived contact with reality.

I like the part after the prototype: real users, real constraints, and systems that still have to feel fast on a bad connection.
