How I can help

One builder.
Full ownership.

A compact engineering partner for founders and teams who need senior-level execution without adding layers of coordination.

A

Full-stack web and mobile apps

Production-ready web platforms and cross-platform mobile apps, built from product planning through frontend, backend, integrations, and deployment.

B

AI integrations and custom agents

Build custom AI agents and production AI systems with RAG, tool calling, voice and document workflows, model evaluations, fine-tuning, and self-hosted inference.

C

Workflow and CRM automation

Automate lead capture, follow-ups, scheduling, reporting, and internal operations by connecting HubSpot or other CRMs with the tools your team already uses.

About / approach

Close to the problem.
Responsible for the outcome.

I work across the stack because product quality gets lost in the handoffs. My best work happens when I can understand the user, shape the system, and keep refining until the details hold together.

Currently at Indusbit LLP, I build production voice AI, streaming services, and retrieval systems. I also partner with teams on focused freelance builds.
