Everything shipped since 2022 — three companies and a workbench.

Featured.

Tech Flairz — 2024 to now

01 Healthcare AI

FoyerCare visit ↗

AI-powered referral intake platform

An AI intake system for home health and hospice orgs that answers referral calls 24/7 through a conversational assistant — capturing structured patient data, verifying the complete referral flow, and routing finished referrals to schedulers in under a minute. HIPAA-compliant end to end.

My part: the backend referral pipeline — intake orchestration, verification workflows, scheduler routing.

02 AI Agents

Numik AI

Agentic software development platform

An autonomous platform that takes projects from idea to locally deployed app — structured step-by-step plans, clarifying questions when things are ambiguous, and a human-in-the-loop execution flow ending in a live preview of the finished product.

My part: core backend systems for agent orchestration — plan generation, stepwise execution, feedback cycle.

03 Web3 Nav

MapMetrics visit ↗

Drive-to-earn navigation platform

A decentralized (DePIN) navigation app rewarding users with crypto tokens for anonymously contributed driving data — offline maps, real-time traffic, and a token economy with a global user base.

My part: developer on the main backend server — features, maintenance, performance, reliability at scale.

04 Maps & APIs

MapAtlas visit ↗

Developer mapping platform

Maps, Geocoding, Routing, and Places APIs — markedly cheaper than Google Maps — plus Atlas Studio (visual map-style designer with live preview), a developer portal, and a community contribution hub.

My part: built and maintained systems across the platform — API infrastructure, portal, studio, hub.

Off-the-clock builds — software, hardware, and things with solder on them

An ESP32 bridge that puts a faulty landline on WiFi — answer, dial, and talk from a mobile app, with two-way call audio streamed over UDP.

Hardware

IR Light Gun build guide ↗

A from-scratch arcade light gun — IR tracking, solenoid recoil, and rumble haptics on a Raspberry Pi Pico. Fully documented build, parts list included.
