Engineer & product builder

I build products and the systems that make them work. I’m a software engineer at Kredivo Group, based in Bengaluru. Previously, I worked with Paytm, WinZO, and Zepto.

Across six years in the industry, I’ve worked where product moves fast and engineering decisions matter. My focus is turning that pace into lasting value: shipping useful products, making deliberate trade-offs, and building systems that hold up in production.

Outside work, I bring that same end-to-end ownership to independent products, from personal planning and multiplayer games to religious services and AI data tools.

Products Built

Give your day a frame. A personal operating system for training, studying, and tracking progress. Daily plans, workout logs, study sessions, notes, and health context—organized around what matters today.

Daily planning · Training & study · Progress tracking · Offline support

Good games. Real opponents. Online chess, Ludo, and Connect 4, with the real-time systems underneath: WebSockets, shared game state, matchmaking, and reconnection handling.

Multiplayer games · Real-time communication · Redis-backed state · Game synchronization

The calculations behind the experience. An open-source service for birth-chart and Panchang calculations, built around Swiss Ephemeris. A dedicated calculation engine that other products can call through an API.

Birth charts · Panchang · Swiss Ephemeris · API service

Trust comes before the booking. A platform connecting people with Purohits, temples, and Hindu religious services. Built around provider onboarding, verification, Panchang, and a thoughtfully coordinated booking journey.

How I build

Understand the person using it. Keep the architecture simple. Make failures visible. Design retries to be safe. Keep humans in control of high-impact AI actions.

I care about the whole product: a useful interface, clear service boundaries, and systems that remain understandable when things go wrong.
