About

Software engineer building products, systems, and AI-native infrastructure.

I started programming long before it became my work, and have built software professionally since 2012 — across product, infrastructure, media, developer tools, and agent systems.

My path runs through competitive programming as a student, a Google internship, creative infrastructure at Smartly and Meta, low-latency audio at Speechify, and engineering effectiveness products at Swarmia. Along the way I co-founded and ran engineering for Tellerpoint, a fintech platform that moved money at national scale.

These days I build production agent systems: task orchestration frameworks, multi-phase LLM agents, human-in-the-loop tooling, and the product surfaces around them. I also work AI-natively, using Cursor and Codex for planning, implementation, debugging, and repeatable automation across my toolchain.

I've spoken at JavaOne in San Francisco on deploying end-to-end Kotlin inside a Java enterprise.

Currently

CTO at Kreia, building autonomous marketing infrastructure for real estate and construction. The work spans customer-signal ingestion, real-time prioritization, multi-phase agents, media generation, and the production platform that holds it together.

How I work

I like calm, direct ownership: understand the product, design the system, write the code, operate it in production, and keep tightening the loop. I enjoy small senior teams where technical judgment, taste, and execution all matter. And I place a high value on velocity, readability and testability.
