I’m a software engineer building reliable backend systems with .NET and modern distributed architecture. I focus on security-by-design, resilience under load, and end-to-end observability so teams can operate with confidence.

At Pine Labs, I engineered a fault-tolerant bulk transaction engine for Amazon using RabbitMQ, consistent hashing, and SQL-backed idempotency to sustain 500+ TPS with zero data loss. I also added resilience patterns with Polly circuit breakers and exponential backoff to prevent cascading failures during peak traffic.

Security and compliance are core to how I ship. I remediated session vulnerabilities by implementing a Force Logout mechanism using Redis Pub/Sub and SignalR for sub-second, server-initiated revocation across distributed clusters. I also enforced TLS 1.2/1.3 and drove PCI-DSS compliance through targeted remediation and dependency upgrades.

I’m equally comfortable modernizing and operating systems. I migrated microservices from .NET Core 2.1 to .NET 8, replaced legacy logging with Serilog for structured ingestion into the ELK stack, and built Grafana dashboards to shorten incident detection. I’ve complemented core backend work with real-time streaming pipelines using Apache Pulsar Functions (<10ms latency) and production support through SQL Server root-cause analysis and performance tuning.
