REGULATED PLATFORMS & SCALE-UPS

API & Platform Integrations

Integration debt compounds quietly. Partner deadlines don’t move. API docs don’t reflect reality. And every quarter the work slips, the cost of fixing it grows. We’ve built in fintech, payments, and compliance platforms where getting it wrong isn’t an option.

07 / Why FREYSOFT

Why clients choose FREYSOFT.

Most agencies are run by operators.

We were founded by an engineer.

Our tech director personally owns every delivery. Not a project manager. Not a VP who hasn’t written code in ten years.

“Built by engineers” means the person accountable for your project writes code. “Run with product discipline” means it ships on time, on scope, with weekly demos and a sign-off at every gate.

Oleg PanchenkoOleg PanchenkoOleg PanchenkoFounder & CEO
4+ yrsAverage client engagementNot a one-project relationship
30+Skill sets
Not juniors bench

Senior engineers on every project, from day one — no bait and switch.

Bad briefs kill more projects than bad engineers.

Not because of the tech. Because nobody had time to write down what’s actually needed — and most agencies won’t do it for you.

We scope it with you — and take the paperwork off your plate entirely.

  • Spec written together in 1–3 sessions — no homework on your side
  • Sign off on Friday, engineers start Monday
