✦ Mark Skrypka — Founding Engineer & Builder
From React Native apps at DataArt to AI agents and products at Cactus, Tree Labs, Recal, and Jack — I ship where the hard part is real users, not the demo.

“AI meeting notes & Slack recaps”
Recal turns meetings and Slack threads into structured recaps, decisions, and tasks — so teams stop taking notes and never lose context. Automatic transcription, true video understanding, and chat with everything that's been said.

“AI agents that handle the work your team can't keep up with”
A studio that designs, builds, and operates production AI agents — voice, workflow, and knowledge/RAG — for ops, CX, and product teams. Custom builds, no SaaS lock-in. I own engineering direction, architecture, and technical hiring across client work.

Founder and client work overlaps by nature. What matters is continuity — DataArt to Cactus, then Tree Labs and Jack, without inventing tidy gaps.

Built cross-platform mobile applications with React Native, focused on iOS delivery, API integrations, performance work, and close collaboration with product, design, and backend teams.
An AI teammate for small teams that live in chat. Give it task and status ops in plain language across Slack, Discord, and Telegram — it acts autonomously across your tools, asks approval before anything sensitive, and remembers how your team works. No dashboard.
Day to day, I'm Founding Engineer at Jack.
“Add a real 1–2 sentence client quote here — the kind that speaks to how you work and what shipped.”
“A second short testimonial goes here. Pull the strongest lines from your Upwork reviews.”
“One more quote to round out the section. Keep each to a couple of punchy sentences.”
Have a product that needs to ship, or an AI feature that has to survive real users? Tell me about it — I read everything.
