Tilt365

Context

Tilt365 is a leadership assessment platform used by organizations worldwide to develop team dynamics and personal strengths. With over 160,000 active users, it was originally built on a no-code platform that limited scalability and made iteration slow and expensive.

The problem

The no-code platform had become a ceiling. Every new feature required navigating around the platform's constraints, the company was paying recurring license costs for something they didn't fully own, and iteration speed was slowing down as the product matured.

The constraint

The hardest part wasn't writing code — it was rebuilding a system I didn't fully control. The legacy platform had limited documentation and external dependencies. I had to deeply understand how it worked, design a sync strategy, and create a new architecture that could coexist with the old system during transition.

The approach

Together with the CTO and the executive team, I led the transition to a custom architecture built with Next.js and Rails. We didn't just rebuild the UI — we migrated assessments, users, infrastructure, and databases while the business was live. At one point, we were running both platforms in parallel and syncing databases while gradually migrating users.

The outcome

The migration gave the company full ownership of its product, eliminated recurring license costs, and unlocked much faster product iteration. Zero downtime during cutover. All 160,000 users transitioned without disruption.

What I learned

Migrating a live system is fundamentally a coordination problem, not a technical one. The code is the easy part. The hard part is maintaining trust — with users who can't notice anything changed, with a team navigating uncertainty, and with a system you don't fully own yet.
