Engineering Services

Bring your product from concept to launch — or rescue it from technical debt.

āš™ļø How We Work

We believe in clarity, ownership, and results.

  • We define scope, deliverables, and success criteria upfront
  • Work is billed by milestones or time-based contracts (for consulting)
  • All source code, designs, and documentation are transferred to the client upon payment
  • We guarantee the quality and functionality of our deliverables
  • Post-launch support and maintenance are offered as a separate engagement
  • We can join your project from day one or jump in to rescue and stabilize existing systems

šŸ“± Mobile Development
  • Native Android (Kotlin, Coroutines, Jetpack Compose)
  • Native iOS (Swift, SwiftUI, Combine)
  • Kotlin Multiplatform (KMP) shared codebases
  • Flutter for rapid cross-platform delivery
  • Example: Booking.com Guest App — led Kotlin migration, Compose adoption, refactored core modules

🌐 Full-Stack & Backend Development
  • Frontend: Next.js, React, TypeScript, Tailwind CSS
  • Backend: Rust (Axum, Tokio), Kotlin / Java (Spring Boot), Python (FastAPI)
  • REST & GraphQL APIs, high-performance async systems
  • Build and deploy TensorFlow / PyTorch models into production
  • Infrastructure: Docker Compose, GitHub Actions, Cloudflare routing
  • Example: Metalbox-store.org — fully self-hosted infrastructure, payments, dynamic DNS, automated mailing

⚔ Embedded Systems & Electronics
  • ESP32 (ESP-IDF), BLE, USB-MIDI, I²C/I²S audio systems
  • Custom PCB design (SMD) with EasyEDA, JLCPCB manufacturing
  • Real-time firmware development in C++ with STL
  • AI integration: Computer Vision, etc.
  • Example: ESP32-S3 Synthesizer — multi-voice audio engine with custom PCBs and DSP

ā˜ļø Deployment & Infrastructure
  • End-to-end Docker Compose infrastructure deployments (web apps, ML services, automation pipelines)
  • Model serving setup for TensorFlow/PyTorch models
  • On-premise or cloud (self-hosted, VPS, or hybrid)
  • Monitoring & observability with Grafana, Prometheus, Loki

🧠 Consulting & Technical Rescue

Untangle the mess. Stabilize and evolve your product.

šŸ”§ Consulting & Code Rescue

  • Product development from scratch: architecture, setup, MVP, scaling
  • Post-launch code cleanup: refactoring messy codebases, removing tech debt
  • Debugging hard, long-standing issues left by external contractors
  • Creating documentation and onboarding guides for long-term maintainability
  • Technical audits, code reviews, and modernization plans
  • Example: Booking.com — refactored critical legacy modules, built new BFF services, led cross-team strategy
