About

Engineering across the stack, now with intelligence in the loop.

Gobi Krishnan Arunachalam

I am a full-stack engineer with 15+ years in web, UI and mobile development, specialising in micro front-end architecture and end-to-end product delivery. My work has spanned e-commerce, healthcare, retail and industrial systems — designing low-level and high-level architecture, leading cross-functional teams and shipping on Agile cycles.

More recently my focus has moved to AI engineering: retrieval-augmented generation, vector databases, embeddings and multi-agent workflows. The interest is the same one that has driven the last decade — making complex systems feel simple to the person using them.

I hold an MCA from Sourashtra College, Madurai (Madurai Kamaraj University, 2008), and I am based in Bangalore.
