I build AI products that hold up in production. I own them from architecture through deploy.

Sep 2025 – Present

Micro

AI-native email and CRM, backed by a16z. Seed-stage, about ten engineers. These four systems are mine, end to end.

Serving ~100 → 1,400 MAU

Drafting / Auto-labelling

Every inbound email gets read once and turned into structure: sender type, status, labels, and a reply draft waiting in the composer. Micro's labels sync back into Gmail, so the classification is visible wherever you read mail. The hard part isn't the model — it's that Needs Response is a Gmail label anyone can toggle, so work is armed on every observation and collapsed by a debounced queue rather than run at ingest.

Pilot

Software Engineer II

Owned the trip planner and worked on a hotel booking flow that processed $1M+ in bookings. Delivered Smart Import end to end and helped migrate the platform from Firebase to MongoDB.

2022–24

CuroStrides

Product Engineer II

One of three engineers on DrCuro, a HIPAA-compliant EHR — scheduling, consultation records, prescriptions, plus a WhatsApp booking flow. Integrated ABHA, India's national health record network, straight against the official APIs instead of through a reseller. Clinics trialled it and it never launched; all of it argued out before agentic coding existed.

2021–22

Velozity

Senior Developer, contract

Built the ECG annotation tool a diagnostics company's technicians worked in daily, and the pipeline that normalized their labelled output for an in-house arrhythmia model. Laid the front end and the data flow the rest of the team built on. Twenty technicians used it every day.

2019–21

StudyMonk

Founding engineer

First technical hire. Built the app, hired the team, and rewrote the product when COVID killed the offline-first version it depended on. The market wasn't ready for the replacement and we shut it down — but I had hired and led engineers before I'd finished my diploma.

Earlier: Roundups (2021) · ShapeAI (2021) · Flabber (first internship)

Benchmark

Deputy

A conformance benchmark for agent tool-call authorization. It runs adversarial calls through each framework's real approval machinery to test argument scope, delegated authority, and escalation quality. Early design stage.

Personal

Pulse

Pulse watches my Garmin data and nudges me on Telegram when my routine slips; months of using it on myself turned a simple notifier into a health-coaching system, with every false alarm or missed intervention shaping the next version.

Beta

TractionSEO

Slack-native SEO agent — drafts, rank tracking, GEO citation monitoring. Private beta.

SDK

GamifyMe

Leaderboards, badges, and XP as an API and SDK, so an app can add progression without designing the schema for it. My first go at shipping something for other developers to build on.

Every first version I've shipped was too confident.

i

Two data points became a trend.

A context builder treated missing data as negative data. The model filled the gaps with a confident explanation and turned two observations into a pattern. I fixed the input, then required every claimed pattern to cite its sample size. The pipeline had erased uncertainty before the prompt.

ii

The work queue reclaims its own failures.

Workers claim due jobs with a lease. If one crashes, the same query that claims new work also picks up expired jobs. Recovery happens during normal operation, removing the need for a separate reaper process that can fail or fall behind.

Architecture through deploy.

Hit me up if you need an engineer to help figure out the system and own what ships, whether you're starting from a blank repo or improving something people already depend on.
