Systems architecture / product engineering / agentic AI
Architect Developer at MÁV TopoRail. I design dependable geospatial platforms, lead complex software delivery, and build mobile and web products—from architecture to hands-on implementation.
I’m a software architect and hands-on engineer focused on reliable, data-intensive systems. Since 2022, I’ve worked on MÁV’s TopoRail geospatial platform, designing scalable services, performance-aware data flows, and production tooling. Across geospatial, 24/7 infrastructure, banking, document workflow, and mobile-product projects, my work spans architecture, technical leadership, implementation, automation, and product delivery.
Organisations & domains I’ve worked with
How I work now
I enjoy agentic AI development—not just prompting for code, but designing the system around the work. Codex becomes most useful when context, tools, agents, automation, and verification operate as one deliberate workflow.
The goal is not more generated code. It is a better system for turning intent into verified software.
Current practice
Intent → evidence
Define context, constraints, and the evidence that will count as done.
Use Codex and specialized agents to research and execute in focused parallel tracks.
Turn repeatable practice into Skills, AGENTS.md guidance, tool integrations, and automations.
Close the loop with tests, runtime checks, visual QA, and human review.
Human checkpointTech lead for DFA — a digital workflow and document system enabling secure storage, photo/GPS/signature attachments, task scheduling, and client-ready digital reporting. Designed solutions from requirements to delivery, mentoring developers and owning the Angular + Spring Boot integration.
Lead developer and operator for KAFIR — the backend platform supporting the VÉDA intelligent camera network. High-availability (24/7), fault-tolerant, scalable, multi-layer system integrating with vehicle registries and other subsystems. Produced system designs/specs, led the dev team, and delivered features in a Java EE stack.
Senior Java developer on Budapest Bank’s new web netbank (go-live: summer 2016). Built backend business flows, implemented web services, customized the bank’s BFO framework, contributed to ExtJS frontend, and supported migration from legacy systems plus mobile integration.
Contributed to a next-generation healthcare system: Java EE development, WebServices, reporting (BIRT), data migration (Talend), testing, and maintenance. Early-career experience that built strong foundations in enterprise delivery and integration work.
Designing scalable geospatial services, performance-aware data flows, and operational tooling for a complex production platform. Turning topology and infrastructure-network constraints into dependable software and clear technical decisions.
Leading development at M&S Informatikai Zrt. as a remote full-time tech lead. Owns solution design based on client requirements, supports and mentors developers, and delivers Angular 14 frontends connected to Spring Boot services (DFA platform and related systems).
Built and operated a fault-tolerant, scalable backend system for the national traffic camera network. Produced system plans and technical specs, coordinated with stakeholders, led the dev team, and delivered features end-to-end as a full-stack engineer.
Delivered backend business flows and services, customized the BFO framework, contributed to ExtJS frontend, supported production hardening, bugfixing, and legacy-to-new data migration, plus mobile integration.
Senior engineer in a SCRUM team building a banking back-office prototype. Introduced development standards, design patterns, and code review practices; supported knowledge sharing and technical decision-making.
Worked on a Java-based property listing platform using modern web technologies and open-source components. Contributed across the full delivery lifecycle.
Built reporting and web UI components, integrated services, performed data migrations, and contributed to platform features (including Eclipse RCP plugins) across multiple projects.
Core academic background that grounded my software engineering path.
Professional training across software engineering, delivery, and product growth.
An iPhone-first product with a web companion for personal trainers, connecting scheduling, client CRM, workout execution, finance, and reporting in one clear operating flow.
An online iOS board-game product with polished interactions, live matches, player profiles, and match history. I use it to refine Codex-based agentic workflows while keeping product quality and engineering judgment explicit.
A mobile logic puzzle game with icon-based equations, progressive difficulty tiers, and a clean, pastel-first interface optimized for quick play sessions.
An open-source Vaadin plugin that provides a Java API for LeafletJS, enabling server-side Java teams to build interactive maps and extend Leaflet with custom plugins and integrations.
