Systems · Research · Always Building
Hey, I am Abhinandan
systems, distributed platforms, and developer tools. always building.
I am an engineer passionate about distributed systems, low-latency execution engines, and developer productivity tooling. Currently, I am an SDE-II at Project44, building a Decision Intelligence platform that orchestrates AI agents to detect, decide, and act in real time, while also architecting internal developer tooling that helps engineers build and ship software faster and more efficiently.
On the side, I am a co-founder of SDE Forge (an interactive system design simulator and mock interviewer) and creator of CodePad (a sandboxed multi-language browser IDE powered by BullMQ & Docker).
I enjoy solving problems and bridging the gap between complex challenges and effective solutions.
