Senior Backend Software Engineer · I build backend systems end-to-end — API design, service architecture, database behavior, identity flows, deployment, and the operational failure modes that don't get documented. Moving toward architecture and technical leadership.
A system is not the happy path. It's everything around it: timeouts, retries, bad input, partial failure, async context leakage, thread-pool starvation, identity edge cases, schema drift, and the 3 AM page.
Code that works once isn't the goal. Code that can be understood, tested, operated, debugged, extended, and trusted under real production conditions — that's the goal.
| Area | What it covers |
|---|---|
| Backend architecture | Service boundaries, API contracts, failure isolation |
| Identity & auth | Token lifecycles, OAuth/OIDC, session edge cases |
| Persistence & data | Schema design, migrations, transactional correctness |
| Cloud-native delivery | Containers, pipelines, observability, operability |
| Process digitalization | Turning fragile manual workflows into trustworthy systems |
- Moving deeper into architecture and technical ownership
- Sharpening identity systems, cloud-native patterns, and async correctness
- Building toward technical leadership — design, mentoring, direction
A selection of personal projects focused on backend engineering, system design, automation, and practical tooling.
| Project | Description |
|---|---|
| Used Car Notify Bot | Telegram bot that scrapes used-car listings, detects new offers, applies configurable filters, and sends notifications with photos and prices. Fun fact: I actually used this to buy a car. |
| Horizontally Scalable i18n Demo | Dynamic i18n for external clients — scalable backend-side translation management instead of hardcoded application text. |
| Java DB Without Spring | Explicit database access without framework abstraction. H2-based testing, SQL schema init, persistence understood from first principles. |
| Java Spring Boot Demo | Spring Boot backend with Hibernate, REST APIs, PostgreSQL, Flyway migrations, caching, Docker, Swagger/OpenAPI, and third-party API integration. |
| PlayStation Portable Content Manager | Cross-platform desktop utility for managing PSP file structures — automated folder creation, filesystem helpers, and practical content-management workflows. |
| Spring Security Demo | In-memory users, HTTP Basic authentication, and role-based authorization in a simple Spring backend. |
| Spring Kafka Producer/Consumer Demo | Two Spring microservices communicating through Kafka — producer-consumer flow, logging-based observability, event-driven interaction. |
| GameMaker Studio Simple Pong | Small GameMaker Studio 2 Pong-style game. Fast hands-on experiment with game development fundamentals. |
