I'm Eugene, a product engineer who builds AI-driven SaaS: assistants, LLM features and the full-stack apps around them. I've also spent years integrating HubSpot with the systems B2B teams run on, so what I build connects to your CRM instead of sitting next to it.
One conversation first. Then the right route for your product: I build it, a vetted partner builds it, or you find out it doesn't need building yet.
Bring your idea, a brief or an agency quote. In 30 minutes you get an honest read on what to build first, where AI actually helps, and what it should roughly cost to build and to run.
AI products, web apps and HubSpot integrations I build myself. Shopify, mobile and other specialist work goes to a partner team I've vetted, with me as your technical lead if you want one.
A written scope before work starts, and progress in small reviewable pieces. Change requests are estimated before anyone starts on them.
Ship to real users, measure quality and cost, and improve from what the data shows. Source code, documentation and access stay yours.
Agencies sell what they build. I start from what your product needs, and sometimes that is a smaller first version, no AI at all, or a team that isn't mine.
Prompts are the easy part. I design for what comes after the demo: evaluation, cost per request, latency, fallbacks and the data the model is allowed to see.
I worked in finance and project management before engineering. Budgets, margins and unit costs are part of every technical recommendation I make.
