01 — Experience

Career

Power electronics to industrial vision to medical devices to automotive AI — each move added a layer rather than replacing one.

Independent platform engineering

Apr 2026 — present
Self-directed · Platforms, real-time 3D, CNC & embedded

Designing, building and operating a private production estate alone — architecture, code, infrastructure, security and operations. More than sixty distinct pieces of work: a multi-tenant business suite behind its own identity provider, a browser office suite with native clients, two marketplaces, CNC and AGV firmware with the cloud services around them, multiplayer 3D worlds held to a frame-time gate, and the dial-out control plane, release engineering and recovery drills underneath. Five servers, more than a hundred hostnames and over 1,300 immutable releases retained — all of it surveyed into a database rather than remembered.

GIS mapping & navigation platform

May 2026 — Jul 2026
Self-directed · Geospatial

A map workspace and a turn-by-turn navigation product on one backend. The web application puts 2D maps, a 3D globe and terrain, drawing and measurement, weather, sun and moon, and live aircraft, ship and traffic layers in one place; native Android and Windows clients share its routing and search. I built the navigation engine — route projection, damped heading, re-routing and road-named voice guidance — an India-focused geocoder over OSRM routing, consent-gated trip telemetry, accounts and subscription billing. 141 commits across six private repositories; the Android client ships through in-app updates.

Industrial chiller design & simulation platform

Oct 2025 — Mar 2026
Self-directed · Industrial HVAC

Six months building the engineering tool for a grain-cooling chiller line: vapour-compression cycle modelling against real refrigerant property data, psychrometric and load calculations, compressor and heat-exchanger selection, and the sizing reports an engineer has to sign. Shipped as a web platform with a native mobile client for use on site.

PathPartner Technologies Pvt Ltd · Automotive

Led development of AI-driven ADAS features — surround-view 3D visualization, obstacle rendering and an in-cabin natural-language voice interface — on Renesas R-Car hardware. Owned performance across the CUDA, OpenGL ES and machine-learning boundary, plus technical direction and mentoring for the feature team.

Robotics Development & Training

2010 — 2012
HobbyRobots · Robotics & technical education

Designed and built domestic and industrial robots, and ran the technical training side of the business alongside it — robotics courses, seminars and hands-on workshops. The full build path stayed in house: schematic design, PCB layout and etching, assembly and bring-up, so trainees followed a board from drawing to working hardware rather than starting from a kit.

PS Electricals Pvt Ltd · Power equipment

Designed power, earthing and distribution transformers and reactors to customer spec up to 5 MVA / 33 kV — winding and core-cutting instructions, oil and cooling calculations, radiator and conservator selection, bills of material, and the AutoCAD drawings production built from, to IS and BS standards.
