From web and mobile apps to backend, infrastructure and long-term support.

Web products

Websites, services and SaaS focused on conversion and speed.

  • Landing pages and corporate websites
  • Account areas and service dashboards

  • CRM and payment integrations

Mobile apps

iOS and Android apps with clear logic and scalable architecture.

  • Support and growth

Backend & architecture

Reliable product logic, API layer and database foundation.

  • Architecture design
  • REST / GraphQL API
  • Databases and queues
  • Documentation and security

Infrastructure & releases

So the product stays stable and scales without surprises.

  • CI/CD
  • Docker / Kubernetes
  • Monitoring and logs
  • Backups and resilience

Automation & bots

Digital assistants for sales, support and internal processes.

  • Telegram bots
  • CRM integrations

  • Technical audit
  • Support and SLA
Why me

Clear process and responsibility

I combine engineering depth with business goals: transparent estimates, predictable delivery, no agency bureaucracy.

Business + engineering

We align on the goal, success metrics and constraints first. The solution must deliver measurable impact, not just “work”.

Transparent estimation

Stages, risks, dependencies and timeline are clear before development starts. No hidden tasks and no surprise “this is separate”.

Product mindset

We prioritize tasks by impact on outcomes. First the critical and valuable work, then improvements.

Maintainable quality by design

Readable architecture, predictable releases, documentation and processes. The product can evolve for years without chaos.

Reliability by default

Monitoring, backups, deployment control and security are standards, not options. The system should be stable from day one.

Communication and ownership

Clear status, next step and proactive updates. I’m responsible not for “tasks”, but for the final outcome.

Cases

From prototype to stable production

Real tasks, constraints and results. More NDA cases — I can show them on a call.

Process

How I work

Every phase ends with artifacts and a clear next step so you always see progress.

  • Discovery

    I dive into the task and define a clear project goal

  • Planning

    I design the structure and build a clear execution plan

  • Design & development

    I design the interface and deliver the product iteratively

  • Launch & growth

    I take the project to release and support further growth

Formats

Work formats

Start with short diagnostics, then choose the format to hit deadlines and avoid surprises.

Turnkey project

When goals and scope can be fixed upfront.

  • Work plan with outcomes for each phase
  • Timeline, budget, and acceptance criteria fixed upfront
  • Smooth release and project handover

For websites, MVPs and launches

Flexible development

When requirements change and iteration speed matters.

  • We prioritize tasks together by value
  • Weekly iterations, demos, and clear progress
  • Transparent scope: what is done and what is next

For evolving products

Support and growth

When the product is already live and you need a reliable partner.

  • SLA, monitoring, and incident response
  • Optimization, improvements, and bottleneck removal
  • Growth roadmap: new features without chaos

For long-term partnership
