What I Do

I build AI agents and the backend systems they depend on. At Zotok.ai, I took an AI copilot from proof of concept to production. It serves 5k+ daily active users and handles 100k+ conversations a day.

My work covers retrieval, agent orchestration and streaming, along with multi-tenant APIs, scheduled workflows and model usage tracking. I write mostly Python, TypeScript and Go, and handle deployment and operations with AWS, Terraform and Docker.

Outside work, I build tools for workflows I use myself: Agent Bridge and Hermes Plugin connect agents to WhatsApp, while Jobwatch helps me find roles and prepare applications. I self-host these projects on my k3s cluster and write about what I learn.

I’m curious about the layers beneath the tools I use: low-level systems, compilers, and the origins of programming languages. I like understanding how code becomes something a machine can run, and why languages work the way they do.

Experience

Zotok.ai · Hyderabad, India

Architected and shipped an AI copilot (100+ ICP customers, 200%+ lead growth). Built end-to-end RAG pipeline with OpenSearch hybrid retrieval (KNN + BM25), multi-graph LangGraph architecture with 4 streaming strategies, and self-hosted it on AWS ECS with Terraform-managed infrastructure. Designed multi-tenant GraphQL layer (Hasura + NestJS), built offline-first architecture reducing bundle from 100+ MB to 15 MB with 60% cold-start latency cut, and owned end-to-end CI/CD cutting release cycles by 35%.

Gramoday (AgriLinks Technologies) · Remote

Built full-stack features for an agriculture community platform using React, Next.js, TypeScript, and Node.js + PostgreSQL (Prisma ORM). Implemented async workflows with AWS SQS and Lambda for notifications, content moderation, and analytics. Focused on low-bandwidth usability and reliable content feeds for rural adoption.
