About

Jarosław Michalik

I'm Jarek — Fractional CTO and founder of Impl. I build products and teams, not slide decks.

10+ years in software. Kotlin, Android, Flutter, Firebase. I've shipped MVPs, scaled teams, and done tech due diligence for investors.

I help dev teams adopt AI-assisted development without the mess. Architecture, standards, code review — the stuff that keeps AI from turning into tech debt. Software craftsmanship, not prompt spaghetti.

Google Developer Expert. Speaker at Droidcon, DevFest, SFI IT Academic Festival. Based in Kraków, working with startups and software houses across Europe, UAE and US.

What Impl does

• Fractional CTO — ongoing CTO-level leadership for startups that need direction, architecture, and delivery hygiene without a full-time hire (service overview).
• AI coding workshops — one day, in-house or online, focused on shared team standards and practical workflows (engineering workshop).
• Tech due diligence, audits, and architecture — for founders and investors when you need an honest technical read before a round or a major bet.

How to reach me

Best next step for most teams is a short discovery call — no pitch decks, just fit and scope (book here) or DM on LinkedIn.
