About our Upwork history: we have built software since 2017 and delivered 120+ projects, almost all through direct contracts and referrals. Our Upwork record is small and was dormant until recently. We are rebuilding it deliberately and price early Upwork engagements accordingly. Everything else here is verifiable - case studies, references and code samples on request. HOW WE WORK - Senior-only engineers, 8+ years each. No juniors billed to your budget. - CET working day with a 4-hour overlap with US East Coast (9 AM - 1 PM ET). - GDPR compliance by default. ISO 27001 readiness and SOC 2 Type II in progress - we tell you exactly where they stand, not claim certificates we do not hold yet. - Code review, tests and CI on every project. You own the repository from day one. Send a short brief and a senior engineer - not a salesperson - replies within one business day with a scoped estimate.
