I build the platforms others build on. Staff Engineer @ Productboard, AI champion.
I'm a product-oriented engineer. I don't write code for the sake of writing code, I need to see the purpose behind it, and I like to understand what I'm building under the hood rather than just generate something that happens to work. I've spent ~8 years at Productboard (employee #11), growing with the company through three tech eras: a Ruby on Rails monolith, distributed systems on Kafka, and now a fresh Kotlin platform I contribute to regularly. Along the way I led the teams and initiatives behind three things I'm proud of: our integration platform (one composable home for OAuth, MCP servers, and custom connectors, replacing a pile of scattered one-off implementations), our public API v2 (exposing Productboard's genuinely complex workspace model through one clean interface), and our MCP server (the thing AI assistants now use to talk to Productboard). These days I'm also Productboard's AI champion. I run sessions, give talks, help teammates get fluent, set our standards, and turn our repositories into AI-first codebases. I use AI across my whole stack, every day. Outside work I scratch my own itches in code. Each project solved a real problem I had: baked_file_system bakes assets into a Crystal binary, shelli gives AI agents persistent shell sessions, and git-treehouse is a keyboard-driven terminal UI for juggling git worktrees. I learn best by building something real and breaking it. Stack: Ruby on Rails · Kotlin · React/TypeScript · Kafka · Postgres · Elasticsearch · Redis · MCP/AI, Crystal, Swift, or anything that is currently needed
