About
I am a Senior Backend Engineer focused on measurable outcomes, technical depth, and end-to-end ownership. I specialize in backend-heavy systems (.NET, Go, SQL), system stabilization, and fast start in existing codebases. Ready to deliver high-quality code and support production from day one.

Experience
Shipped rapid SaaS prototypes to validate ideas and secure early customers. Designed EU ecommerce compliance workflows to reduce launch delays for Asian sellers. Built tooling to track mandatory documents and evidence for audit-ready submissions. Current stack: Go and TypeScript.
Removed .NET bottlenecks in high-scale AdTech paths to restore reliable production throughput. Optimized multi-region Kafka consumers to keep peak-load event delivery consistent. Reduced production error alerts by ~40% and unblocked 3 cross-functional teams. Sustained pipelines handling millions of events per hour without delivery regressions.
Delivered production-style Go services with concurrency and observability baked in. Shipped Dockerized prototypes plus tests to validate reliability early. Reached 100% core-logic coverage on a distributed rate-limiter (race detector + integration tests).
Refactored PostgreSQL procedures to move ingestion cadence from 15 to 5 minutes (3x resolution). Scaled backend ingestion to higher write-load across thousands of endpoints. Validated results via ingestion logs and Azure Monitor metrics.
Researched backend architecture, performance bottlenecks, and scalability trends. Evaluated OpenTelemetry and structured logging to reduce debugging time in microservices. Produced a benchmarking report comparing 3 tracing providers on latency and memory overhead.
Delivered technical research and system integrations for specialized product environments. Built TypeScript and infrastructure foundations that supported production scaling. Standardized API contracts with JSON Schema + TypeScript, cutting integration time by ~2 weeks.
Built a .NET CLI to detect breaking changes during Dynamics migrations. Cut manual code audit time by ~80% per project (hours to minutes). Eliminated human error in deprecated API detection across NAV codebases.
Led a zero-downtime migration of a data-entry platform to Azure. Contributed to a system rewrite and query optimization workstreams. Improved reporting query P95 latency by ~50% based on Azure SQL Performance Insights.
Built internal tooling for ticket reconciliation and accounting workflows. Automated spreadsheet data-entry tasks to reduce operational errors. Saved ~10 hours per week of manual accounting labor.
Developed Unity3D mobile game features, including ads and in-app purchase flows. Ensured reliable transaction handling in the monetization module. Maintained a ~99% crash-free rate based on production analytics.
