ENGINEERED PLAYGROUNDS
Interactive showcases of systems work — built to be touched, not just read about.
Rate Limit Visualizer
Real-time algorithm playgroundInteractive visualization of three rate-limiting algorithms (Fixed Window, Sliding Window, Token Bucket) under live traffic patterns. Engineered as an observability-style dashboard.
Concurrency Playground
Queues, workers, and overloadSee how concurrent task processing behaves under bounded queues and worker pools. Visualizes FIFO/LIFO/drop strategies, queue saturation, and dropped tasks in real time.
Circuit Breaker Simulator
Resilience pattern walkthroughWatch the closed → open → half-open state machine react to failure thresholds, recovery timeouts, and probe-driven recovery. Built as a live reliability dashboard.
Load Balancer Playground
Traffic distribution algorithmsCompare round robin, least connections, IP hash, and random distribution across a tunable server pool. See routing decisions, health, and load skew in real time.
Event Flow Studio
Producer · partition · consumerA live model of event-driven architectures — producers, partitioned topics, consumer pools, retry loops, and dead-letter queues. Explore lag, retries, and DLQ accumulation.
Kafka Partition Visualizer
Cluster topology + rebalancingDistributed streaming visualizer — brokers, partitions, consumer ownership, and rebalancing animations when consumers join or fail.
Saga Pattern Simulator
Distributed transaction rollbackSee orchestrated and choreographed saga execution — forward steps, configurable failure points, and automatic compensating rollbacks step-by-step.
Webhook Delivery Simulator
Retries · backoff · DLQVisualize webhook delivery reliability under failures — none / fixed / exponential retry strategies, retry timeline view, and dead-letter queue handling.
ArchFlow · Architecture Canvas
Design · simulate · explainInteractive architecture canvas — drag-drop nodes, draw connections, run live simulations across request / event / infra layers. ArchFlow Lite, K8s, Failure, and Interview modes with 4 preset architectures.
BACKGROUND
I'm a software engineer and technical lead based near Budapest. For the last six years I've focused on backend distributed systems — designing microservice architectures, message-driven pipelines, and multi-tenant platforms that have to stay fast and reliable at scale.
I built and exited MusicLoots, a global music-rights and licensing platform, as its only technical founder. Since then I've led architecture and a team at Asura on real-time enforcement systems, co-designed Sense/Net's legal-document platform for TransPerfect Legal, and I now split my time between leading engineering at Campus Codeworks and building Fitoris.
I care about systems that hold up to load, codebases that stay legible as they grow, and small teams that ship.

NOTABLE OUTCOMES
MusicLoots — acquisition
Built a global music-rights platform from zero as the only technical founder; deployed across 31 countries before the company was acquired in 2024.
TransPerfect Legal platform
Co-architected a high-throughput legal-document processing platform that underpins TransPerfect Legal’s document workflows.
Real-time enforcement systems
Designed real-time license-plate-recognition and traffic-enforcement pipelines at Asura Technologies.
