Cloud & DevOps
Production deployments on Azure, Oracle Cloud, and AWS using Docker, Kubernetes, Terraform, ArgoCD, and GitOps for CI/CD and observability.
Data & Search
Experience with PostgreSQL including row-level security, MongoDB, Redis, and Azure AI Search, including replacing legacy search providers with modern adapter-based implementations.
API Design & Spec-Driven Development
Introduction and governance of API spec-driven development using OpenAPI and AsyncAPI, including internal developer platform foundations with service templates and internal packages.
Architecture & Platform Design
End-to-end ownership of architecture decisions including microservice platform redesign, observability, API design-first governance, and scalable high-traffic public-sector systems.
ERP & FinOps Platform Development
Mapping and digitizing contract-to-cash workflows into modular capability platforms with approval trails, tamper-evident audit logs, and e-invoicing integrations including NAV Online Szamla.

Project history
Built an agent-based platform that turns a task note into a reviewed pull request against production repositories. All model traffic crosses a fail-closed PII service with deterministic Hungarian and English recognizers, reversible per-run tokenization, hash-chained egress audit, per-project spend ceilings, and a pinned no-training provider allowlist. Instrumented review-gate pass rate and change-failure rate using TypeScript, Fastify, PostgreSQL, React, Kubernetes, and OpenRouter.
Mapped the contract-to-cash workflow for Hungarian service SMEs and government suppliers into 24 capability modules with approval trails and tamper-evident audit logs. Spec-first Fastify services with generated OpenAPI and AsyncAPI clients, PostgreSQL with row-level security, and e-invoicing integrations including Szamlazz.hu, Billingo, and an in-house NAV Online Szamla adapter verified against the NAV test environment. 400+ merged pull requests over two years.
Work embedded in client engineering organizations, turning business problems into shipped systems: platform redesigns, partner integrations, high-traffic public services, and search modernization. Own engagements end to end including scoping with stakeholders, architecture, hands-on frontend and backend implementation, CI/CD and observability, and enablement of client teams. Build reusable foundations including spec-first API templates, internal developer platform pieces, and delivery quality gates.
