We choose technology for your problem-not the reverse. What we use every day.
Five clear stages. Demos every two weeks. You see the code, access tasks and builds. You know exactly what you're paying for.
We understand your task, users, competitors. Define requirements, lock budget and timeline.
Architecture, mockups, prototypes. Approved before any code-no costly rewrites later.
Two-week sprints. Code review, tests, demos continuously. Working code in your repo same day.
Functional, integration, load testing. We ship only production-ready code.
Deploy, configure monitoring. Warranty period, technical support, ongoing development available.
No middlemen diluting information. You speak directly with the CTO, CEO and tech leads who solve your problem.

6 years in the IT business. He started as a developer, then moved into management: leading project teams, building development processes, and owning client and business relationships. He combines technical understanding with the commercial side - estimation, negotiation, timeline and budget management. He takes on the admin and the communication so you don’t lose time or nerves on it. His principle: “I answer for the result with my own name and face” - no hidden costs, no surprise deadlines, no murky communication.

8+ years building complex digital products. For most of his career a product tech lead in travel: he ran the mobile track (iOS, Android, watchOS), built Go backends, and set up the processes for a team of up to 10 engineers. He has shipped dozens of production apps with real-time processing, external API integrations, and cross-device sync. Strongest in native mobile development (Swift, SwiftUI, Kotlin, Jetpack Compose, KMP) and Go. He owns architecture, security, and quality - personally designing solutions, choosing the stack, and reviewing critical components.

3+ years in mission-critical systems. He progressed from network engineer through SRE and DevOps to Senior DevOps / MLOps in large corporate systems (names under NDA). He has automated infrastructure from scratch: Kubernetes, full GitOps CI/CD (GitLab CI + ArgoCD), IaC (OpenTofu, Ansible), monitoring and alerting. Notable results: service uptime from 89% to 99.9%, deploys from a week to one hour, engineer onboarding from 3 days to 3 hours, and $2M in freed resources. Credo: “99.99% uptime is a planned goal, not a dream.”
And we won't fake them.
