Head of EngineeringThings I've actually shipped.
A CTO's portfolio should be products, not decks. Below: the six products I designed, built and launched in 2026 under Atrix — each with the problem, what was built, the stack and the proof — followed by the platforms I led at banks, governments and startups over the last decade.
Six production products in one year
Every one of these is live. They span three languages (TypeScript, Rust, Go), telephony, email infrastructure, analytics at 42.7k events per second, and a marketplace with a Play Store app. They were built with heavy AI-assisted delivery — the same way I'd run an engineering org today.
Atrix
2026AI workspace SaaS for small teams — CRM, projects, hiring, HR and billing in one place.
ProblemSmall teams juggle six tools that don't talk to each other, and their AI assistants can't reach any of them.
BuiltNext.js App Router on Prisma + PostgreSQL with Better Auth and Stripe subscriptions, a remote MCP server with OAuth 2.1 and scoped, revocable tokens (49 grantable scopes, write-implies-read), an in-app agent, and an Expo iOS app. One MCP connection also reaches Atrix Analytics, Atrix Mail and PrimeLeadFinder.
ProofListed in the official MCP Registry; shipped CRM, HR, agreements with e-sign, calendar, pages and people modules in one year.

VoDialer AI
2026AI outbound voice dialer built as a full VICIdial replacement for US Medicare call centres.
ProblemLegacy dialers are 20-year-old PHP; nobody has rebuilt the whole stack with an AI agent as the caller.
BuiltEight Rust services on FreeSWITCH and Kamailio, a real-time speech-to-text → LLM → text-to-speech cascade (AssemblyAI, DeepSeek, ElevenLabs/Fish), a platform console with roles, TOTP and audit logs, and an Expo mobile app.
ProofReal reply gap of ~1.2 s on live PSTN calls; designed for 100+ concurrent conversations.

Atrix Analytics
2026Product analytics platform (a PostHog alternative) written in Rust on ClickHouse.
ProblemAnalytics SaaS pricing scales with events; a lean Rust ingest changes the cost curve entirely.
BuiltRust ingest + query services over ClickHouse with feature flags, A/B experiments, session replay, and an AI analyst exposed over MCP.
ProofIngests 42.7k events/s on a single CPU at 66 ms p99.

Atrix Mail
2026Multi-tenant email hosting with a developer sending API and AI webmail.
ProblemTeams want their own domain mail plus transactional sending, without stitching three vendors together.
BuiltPostfix, Dovecot and Rspamd with SPF/DKIM/DMARC, a Bun API, PostgreSQL + pgvector semantic search, Stripe billing, and a 41-tool MCP server published on npm.
Proof41-tool MCP server on npm; per-mailbox billing live.

RentGari
2026Car-rental marketplace for Pakistan that gives every agency a free branded storefront.
ProblemRental agencies in Pakistan run on WhatsApp and Facebook posts, with no verified reputation layer.
BuiltRust/Axum API, Astro web, WhatsApp OTP sign-in, verified listings (photo + insurance + vehicle checks), ops suite with roles, drivers, chat and promos, plus an Android app.
ProofLive with driver-first bookings; Play Store listing published.

Case study Switchboard
2026The shared messaging layer behind all of the above — WhatsApp and SMS with multi-provider failover.
ProblemEvery product needs OTP, templates and opt-out handling; building it once saves it five times.
BuiltGo service with Twilio, Telnyx, Infobip and Plivo failover, OTP verification, template management and opt-out handling.

Case study Platforms I built or led for others
The products above are mine. These are the ones I built inside other organisations — as an engineer, CTO, head of engineering or mentor. The about page tells the story in order; the experience timeline lists what I did at each.
