Hi, I'm
I turn manual processes into working software for banking and industry. From analysis and design, through code and architecture, to deployment and maintenance.
I build systems that take repetitive work off people's plates, mainly in banking and industry, where processes are big, data is messy, and mistakes are expensive. I know what software looks like when hundreds of people use it every day for real work.
My toolkit is .NET: C#, ASP.NET Core, EF Core/Dapper, MSSQL/PostgreSQL and Blazor. I lead small project teams, gather requirements, design from scratch, write the code, and stay accountable for the system working, also after it ships.
After hours I run my own homelab and self-hosted apps, and I'm building a modular SaaS and a real-time market-data processing platform. A Master's in cybersecurity, because application security should be a default, not bolted on at the end.
Architecture first
Event storming, data model, module boundaries, flows. Implementation then becomes a consequence, not guesswork.
Communication is the baseline
Project status shouldn't raise extra questions. I flag risks and delays first, along with what I propose to do next.
Technological pragmatism
A boring stack means a calm production. Proven tools instead of trendy ones are often a real saving.
What I use day to day at work and after hours.
Selected commercial and personal projects.
Central system managing the company's organizational structure, access control and reporting. A single source of truth with full change history (and its management), interactive dashboards and XLSX exports. I'm responsible for the project end-to-end.
A series of tools automating consecutive phases of a single customer case, covering distinct business processes. I analyzed flows, identified automation opportunities and built tailored solutions with dashboards and exports for a specific operational area.
A lightweight tool that generates structured notes from clipboard input and predefined keyword configurations. Brings measurable time savings to analysts. I designed the core logic and refined the UX based on feedback.
A large-scale project aggregating data from multiple internal source systems. I co-built automation components (robots) responsible for extracting, transforming and normalizing data, with an acquisition layer resilient to changes on the source side.
A platform for improving agricultural production and city infrastructure usage, based on IoT and a modern web interface. I designed and implemented a module enabling communication between measuring devices and the application over the SNMP protocol, and supported the development of the remaining components.
Internal system for employee time tracking, project progress monitoring, company structure management and financial reporting. I developed new features, modified existing logic to match evolving business needs, resolved reported issues and worked directly with stakeholders on requirements.
A personal life management app with a plugin-based architecture, where each module (budget, habits, todo, planner, trackers) can be enabled independently from the rest of the functionality. Designed with multi-tenancy and per-module licensing in mind, with a deployment plan ranging from local Docker for personal use to the cloud as a product. Planned in a web version (MVP) and a mobile one.
A private real-time market-data stream-processing platform. Self-hosted 24/7 deployment. Event-driven Python core (asyncio, ingestion via WebSocket and REST polling, multi-stage filter pipeline), SQLite with versioned migrations and self-heal, FastAPI split into admin/public surfaces. CI/CD: GitHub Actions → GHCR → Coolify, container under supervisord, exposed via Cloudflare Tunnel.
Self-hosted infrastructure for data, media and personal apps. Proxmox VM/LXC hypervisor, external access exclusively through Tailscale and Cloudflare Tunnel. No ports exposed to the public internet.
