I build high-load fintech backends, payment systems, and data platforms.

I've built and scaled backend systems for 12Go Asia, Alpha Affiliates, RusOil, VisualDNA, and financial web products including ruru.ru. My work spans high-load telemetry, real-time bidding, ERP platforms, crypto payments, bank guarantees, and event-driven data processing.

At 12Go Asia, I developed Symfony and Go services for a telemetry platform processing millions of events per day, improving throughput, latency, monitoring, and operational reliability. I optimize ETL workflows, databases, caching, and secure batch and streaming pipelines for high-volume workloads.

I've delivered crypto payment integrations, GameFi tokenomics, CRM platforms, Telegram bots, SaaS banking applications, insurance back-office systems, and crypto algo-trading tools. I work across PHP, Laravel, Symfony, Go, SQL databases, Kafka, RabbitMQ, Docker, CI/CD, automated testing, and secure API design.

With more than 15 years in technical leadership, I lead architecture and delivery, mentor engineers, review code, and work closely with product and business stakeholders from requirements through production.
