Software engineer with 14 years shipping across the stack — full-stack web, mobile, backend, platforms, payments, telematics. Currently on Microsoft's Consumer Commerce team (subscriptions for M365, Copilot, Xbox Game Pass). Side projects after hours.
I'm a software engineer with 14 years shipping across the whole stack — full-stack web, mobile, backend, platforms, payments, computer vision, telematics. Whatever the problem hands me, I learn the tools and build the thing. Today I'm a developer at Microsoft on the Consumer Commerce org in Redmond — the team that runs subscriptions across the entire Microsoft consumer ecosystem (Microsoft 365, Copilot, Xbox Game Pass, and friends). Hundreds of millions of users, one hot revenue path, zero tolerance for downtime.
Before Microsoft I spent a year and change at Target
building nationwide PCI-compliant payments services — integrating
with Worldpay, BAMS, Chase Pay, TSYS and the rest of the merchant zoo
using jPOS, ISO 8583, and Netty. Before that, four years
at Lender Price in Pasadena shipping full-stack
mortgage tech, browser to database. The first chapter was three and a
half years at Infosys in Mysore, where I learned
what good SDLC discipline actually looks like.
I care about contracts over cleverness, observability from day one, and writing things down so the next person — or me, in three years — can pick up where I left off without spelunking through tribal knowledge.
I'm a perpetual tinkerer. The stack list below isn't loyalty — it's curiosity. New language, new database, new runtime, new protocol — if it looks interesting I'll spin it up over a weekend and learn it by shipping something with it. The projects further down are the receipts.
… and a long tail of "tried it once, kept the notes". New stacks welcome — that's the fun part.
None of these pay the bills — they're what I build on weekends, after the day job, when an idea won't leave me alone. A rolling cross-section of things I've shipped, am still in the middle of, or have happily archived.
Self-hosted, privacy-first vehicle telemetry
Open Telematics & Event Logging — a multi-brand telematics platform with four versioned contracts, a sandboxed plugin model, and observability built in. Kotlin + Spring Boot, Python analytics, Next.js + Expo UIs. AGPL-3.0-or-later. The lessons of TeslaSync, distilled into one open standard.
Self-hosted Tesla fleet intelligence with Helix AI
Self-hosted Tesla telemetry, analytics, automation, and 65+ remote command endpoints — for one car or a fleet. Includes Helix, an opt-in AI assistant with 54 user-toggleable features. 197 SQL migrations, 21 frontend feature areas, 13-service Docker stack, Helm chart.
Self-hosted wearable health data, one API
Connect Fitbit, Garmin, WHOOP, Strava — and more — to a single API you control. TypeScript monorepo, multi-tenant, idempotent syncs, AES-256-GCM token vault, BullMQ workers, correlation + anomaly engines, MCP server for AI assistants, Next.js 16 PWA dashboard. AGPL-v3.
Self-hosted Spotify analytics — 40+ dashboards
Think Spotify Wrapped, but year-round and running on your server. Syncs your listening history every 15 minutes; surfaces top artists, genre breakdowns, Music DNA radar (danceability / energy / valence / acousticness), mood analysis, calendar heatmaps, and 35+ more views.
Engineering at the heart of Microsoft's Consumer Commerce organization — the platform that powers subscriptions across the entire Microsoft consumer ecosystem (Microsoft 365, Copilot, Xbox Game Pass, and friends). Architecting and operating hyperscale subscription infrastructure that translates every credit-card swipe into a hundreds-of-millions-of-users subscription business.
Engineered nationwide, PCI-DSS-compliant payment processing services for Target's Payments organization. Integrated with external merchant networks (Worldpay, BAMS, Chase Pay, TSYS, Tandem) over TCP/IP using Netty and WebClient. Operated deep in the cards-and-rails substrate of retail at hyperscale.
Joined as an engineering intern; advanced through Developer to Senior Software Developer over four years. Full-stack mortgage technology — requirement elaboration through customer demos, browser through database. Authored technical manuals that became the team's onboarding cookbook; shipped an OCR document-scanning module on OpenCV during the internship.
Three and a half years at Infosys spanning the full software development lifecycle — analysis, design, implementation, and production support. Refactored core application modules, delivering 25%+ improvements in code quality and runtime efficiency. Awarded Rank #1 in performance appraisal in consecutive cycles (2013-14 and 2014-15).
Occasional essays on platforms, distributed systems, and the long-horizon practice of building software.
Email is the fastest way to reach me. Always happy to nerd out about telematics, distributed systems, self-hosting, or homelabs.
