I'm Deep Chakraborty, a Senior Systems Architect and AI/ML Engineer with 14+ years of experience shipping at scale. I've gotten my hands dirty across JavaScript, TypeScript, ReactJs, NodeJS, C#, PHP, Python, Swift, Kotlin, Dart, and more. Most recently I was sole architect across 23 concurrent products at Ogoul Technology — the headline was re-architecting KT Messenger from 850 to 1.1M+ active users in 6 months, sub-2-second loads, full Signal Protocol E2EE. Before that I grew SocialBlox to 8.2M users with a 3-person engineering team — adopted by the Mexican Government and Election Commission. And going all the way back to 2012, I built a voice AI assistant (L.I.N.K.S) with custom ASR and TTS, before Siri or the Transformer architecture existed — 280K paid users, all organic.
I'm CTO and founder of Deep Voice AI Limited, my own venture building full-duplex conversational voice agents. I'm also the creator of DVAI-Bridge — a patent-pending open-source local-AI inference substrate that unifies nine on-device inference engines behind a single OpenAI-compatible API across seven language SDKs. UK Patent Application GB2611312.6 pending, sole inventor.
I work end-to-end — frontend frameworks, backend microservices, real-time systems with WebSocket and Kafka, SQL and NoSQL databases, AWS and Azure cloud infrastructure, AI/ML pipelines with RAG, agentic systems, and edge inference. I speak English, Bengali, Hindi, and I'm picking up Japanese — because why not? For a deeper dive, check out my CodersRank profile.
