I build production SaaS at scale — and I ship the AI that runs on top of it.
10+ years across React, React Native, Swift, Node, GraphQL, AWS, and Agentic AI workflows. Helped scale Waiterio to $600K ARR across 5,000+ businesses in 40 countries, processing $2M+ in annual GMV.
I'm the engineer you call when the platform has to actually work.
For 10 years I've been the person on small remote teams that ships across the whole stack — frontend, backend, native iOS, native macOS, Android, GraphQL APIs, cloud infrastructure, AI agents — without it falling over.
Most recently I helped scale Waiterio's POS to $600K ARR across 5,000+ restaurants in 40 countries with 99.99% uptime. Before that I founded a two-sided React-Native marketplace with real-time GraphQL subscriptions. Right now I'm building Agentic AI pipelines (Claude + OpenClaw + Microsoft Graph) that replace entire manual workflows for a Houston energy company — and shipping my own product, PulseBizz, on the side.
Web, native, backend, infra, AI — wherever the bottleneck is.
6+ years on remote international teams. Houston-based.
From product spec to AWS CDK infra and post-launch ops.
The showroom.
Eight production products. Real users, real revenue, real code. Hover to peek — click to open the live site (or repo).
A decade of shipping production SaaS.
Senior engineer across three companies — one acquisition-ready flagship I helped scale, one founder run, and one current Agentic AI contract.
-
AI Software Engineer (Contractor)
Elite Energy Consultants- Architected an Agentic AI pricing engine (OpenClaw + ChatGPT + MS Graph) replacing minutes-per-quote Excel digging with instant best-rate lookups.
- Built an AI lead-gen pipeline on 50,000+ ERCOT premise records — delivering 200+ fully-qualified leads/month with zero manual lookup.
- Automated the entire Zoho CRM deal workflow — reps now upload a utility bill and the AI handles account creation, linking, dedup, and sync (~10x productivity).
- Shipped a real-time React analytics dashboard that improved sales workflow efficiency by 40%.

Full Stack Software Engineer
Waiterio- Scaled the POS to $600K ARR across 5,000+ restaurants in 40 countries — MRR $6K → $50K, 99.99% uptime, $2M+/yr in GMV.
- Worked daily inside a Yarn-workspaces monorepo of 180+ packages and 50+ independently deployable services.
- Built native iOS + macOS (Swift) and Android (Java) thermal-printing stacks — with in-process printer emulators and full Quick/Nimble + IOKit-mocked test coverage.
- Shipped the white-label ordering platform that processed $2M+ in annual GMV and drove a 25% COVID sales lift for merchants.
- Shipped the SVG floor-plan Tables editor — one of the most-used surfaces in the POS and a key sales-demo differentiator.
- Contributed across 5 sister SaaS products: Globo, Polyblog, Multilocale, Imagelato, and Stiloso design system (130+ icons).
-
Full Stack Software Engineer & Founder
Codegineers / GetGrocery- Built two React Native apps (shopper + merchant) on iOS + Android sharing a single Relay Modern GraphQL contract.
- Designed a real-time order pipeline over GraphQL Subscriptions + WebSockets, with Redis pub/sub for multi-instance fan-out.
- Used Realm for on-device offline-first state and MobX for cross-screen reactive stores.
- Built the Node + Express GraphQL API with Passport auth and a Sequelize/PostgreSQL data layer, plus push notifications end-to-end.
A toolkit deep enough to ship anything.
I've worked across the full surface — frontend, backend, native iOS & macOS, native Android, cloud infra, and the agentic AI layer that increasingly sits on top.
