Building High-Scale Products and High-Performing Teams

Built and operate a proprietary market monitoring platform used to track crypto market structure, liquidity flows, and trading opportunities in real time.

• Real-Time Engine: Designed a custom data engine collecting and processing live order book and trade data from multiple crypto exchanges.
• Data Ingestion: Built resilient, fault-tolerant ingestion pipelines handling continuous websocket feeds with zero data loss.
• End-to-End Execution: Personally designed, coded, and deployed the entire infrastructure, making it a daily-use research tool.

Rebuilt the server-side infrastructure for one of the world's most popular mobile shooters — without stopping the game for its millions of players.

• –70% Latency: Redesigned server model using Akka actors and co-located in-memory caching, eliminating database round-trips.
• Zero-Downtime Migration: Migrated 20TB+ of player data across continents and consolidated 4 Cassandra rings into one cluster with zero player-visible downtime.
• Reactive Pipeline: Replaced synchronous writes with Kafka event streams feeding Cassandra — decoupled, durable, and horizontally scalable.

Introduced AI-assisted development tooling to the backend team, measurably compressing delivery cycles for server-side work.

• –25% Delivery Time: Compressed time-to-market for server features and improvements by introducing LLM-assisted coding and testing workflows.
• +30% Feature Capacity: Freed up engineering bandwidth, enabling the team to ship 30% more quality-of-life and polish features per sprint.
• Team-Wide Adoption: Scaled AI development tooling across a team of 9 backend developers, establishing repeatable, secure guidelines.

Led the design and delivery of a proprietary banking document management platform from scratch — replacing a fragmented microservices chaos with a coherent, maintainable system now deployed at multiple banks.

• Architectural Reset: Replaced an ungovernable "microservices zoo" with a clean Akka Cluster system built on a component-based model.
• Developer Experience: Teams write plain, readable business logic in Scala — no fighting the framework.
• Real Production: Live at several commercial banks. Proven, stable, and growing.

Served as a core member of the architecture committee on a $15M+ platform initiative at one of the country's largest commercial banks.

• Strategic Governance: Shaped technology decisions across the entire integration layer for a bank operating at national scale.
• Resilient Architecture: Designed the distributed microservices and document storage approach adopted as the bank's standard.
• Cross-Team Alignment: Coordinated legacy architects, external vendors, and internal teams under tight compliance constraints.

Built and shipped an Enterprise Service Bus with a visual routing designer, deployed at major commercial banks and subsidiaries of international institutions — leading a team of 19 engineers.

• Scale Deployments: Active in production at leading commercial banks and local subsidiaries of international banking groups.
• 19-Person Team: Led the entire engineering department that designed, built, and maintained this platform.
• Visual Routing: Designed a low-code configuration canvas that drastically cut integration setup times for bank operators.
