A software engineer turned entrepreneur, 19+ years in. I lead NerdDevs — a 20+ strong team building AI-driven products, scalable SaaS and EdTech across three continents. I don’t manage projects; I architect them — cloud on AWS, Azure & GCP, LLM pipelines, messaging moving millions of texts a month, and assessment platforms trusted by the world’s biggest certification bodies.
Platforms I’ve architected and shipped — client work and NerdDevs’ own products, from AI assistants and messaging backends to assessment systems trusted by global certification bodies. Some clients stay unnamed; that discretion is part of the engagement.
Architect · AI pipeline
An AI chat companion with GPT-4/5 and Vision-powered image analysis. I designed the architecture and AI pipeline end to end — a high-throughput Node.js backend built to survive viral growth.
100K+ users · 99.9% uptime
System & messaging design
A second phone number that lives in an app — text and call without handing out your real one. I own the queue-driven system design where deliverability is the product.
5M+ texts delivered / month
