Product Engineer building SpellType’s private on-device AI autocomplete and consumer mobile products.

India

Message

With SpellType, I chose a privacy-first, on-device approach to writing autocomplete and built app-specific accessibility integrations to keep it local and responsive on 8 GB Macs. I also developed Python/MLX training tools and reached sub-200 ms median suggestion latency on warm eligible requests.

At Shuru Technologies, I owned Olly’s iOS delivery through its App Store launch and worked across AI-powered web products and a production point-of-sale app. Earlier at RailYatri, I improved crash-free usage from 92% to 98%, built and maintained five production Android apps, and led two developers while staying hands-on.
