### Juraj Kapasny, CTO at Stratodata

Before Tin came on board, our deployments were executed from my laptop and our auth layer was just a copy-pasted Google widget. He built a proper CI/CD pipeline and integrated Zitadel from scratch - two weeks, and it's been running well since. On top of that, the way he restructured the repo made a real difference - working with it using LLMs is noticeably easier now and they produce better quality code. The communication was clean, the delivery was clean, and when we paused mid-project he gave us an honest read on what was still missing. That last part is rare. We could own the budget and use it open-eyed.

    <h2>Roam — Real Estate Insurtech, From Startup to Scale</h2>
  </div>
  <p>Roam operates at the intersection of real estate and insurance — specifically, the assumable mortgage market, where a buyer takes on a seller's below-market rate loan. The compliance and coordination requirements are significant: lenders, insurers, title companies, and both sides of the transaction, all moving on the same timeline.</p>
  <p>I came in as a technical partner across the early scaling phase. That meant integrations with the financial and insurance infrastructure, architectural decisions that had to hold under growth pressure, and the business understanding to know which shortcuts would cost them later. Startup work: high ambiguity, high stakes, no tolerance for slow.</p>

  <h2>Stratodata — From Prototype to Production</h2>
  <p>Stratodata is a data science toolchain company — their product helps e-commerce and retail businesses move from gut-feel operations to genuinely data-driven ones. Good vision, real clients, growing team. And a codebase that had been built to prove the idea, not to run it in production.</p>
  <p>I took on the engineering professionalization: proper authentication architecture, CI/CD pipeline, deployment standards, and the kind of code quality baseline that lets a team grow without the wheels coming off. The goal wasn't a rewrite. It was a floor — reliable, testable, deployable.</p>

  <h2>Redfolder Research — Legal Workflow Infrastructure</h2>
  <p>Redfolder Research runs a high-volume insurance policy investigation service for personal injury attorneys — hundreds of case steps a day, across dozens of concurrent matters, with timing and accuracy requirements that can make or break a settlement.</p>
  <p>I built and extended their core operational software: a system deeply integrated into Jira that manages the full case lifecycle, from order intake through paperwork processing, document storage, and researcher coordination. When the existing tooling couldn't handle the throughput, we didn't replace it — we engineered it to scale.</p>
  <p>The result is infrastructure that runs quietly inside a law firm's Atlassian environment, processing the volume of a mid-size operations team without adding headcount.</p>

    <h2>Kiwi.com — FinTech Architecture and COVID Restructure</h2>
  </div>
  <p>People manager and Software Architect in Kiwi.com's booking and financial systems during the company's growth phase — 12,000 automated traveler itineraries daily. I led the FinTech department through the COVID-19 shutdown: restructured the engineering organization, preserved the core product, and came out the other side with the platform intact.</p>
  <p>Features I designed: baggage system rebuild, post-booking extras, handling fee monetization. The kind of infrastructure that runs quietly and costs a lot when it doesn't.</p>
