I built and optimized backend components for a payment processing platform handling hundreds of thousands of transactions daily under strict PCI-DSS reliability constraints.

I improved reliability by tightening error handling, retry behavior, and observability around high-volume transaction flows.

I also optimized high-concurrency payment flows using .NET Core and gRPC, helping ensure sub-second latency under peak load.

I delivered backend components for a mission-critical internal platform used by thousands of employees across 12 countries.

I developed custom automation and PowerShell templates that reduced team time-on-task by 53% and cut support ticket resolution from hours to minutes.

I also improved production supportability by extending Prometheus and Grafana monitoring around backend service health, operational workflows, and failure-prone integration points.

I designed and delivered cloud-based .NET microservices for large-scale health-claim digitization, processing tens of thousands of records daily.

I coordinated technical delivery within a 4-engineer remote team while remaining hands-on with backend implementation, database work, service integration, and production support.

I also established CI/CD pipelines and monitoring, improving deployment reliability and reducing incident response time by 41%.

I owned end-to-end delivery of Azure-based ERP and business-system integrations, from client requirements and solution design through database schema, authentication, implementation, deployment, and production support.

I architected and delivered cloud-based microservices supporting business-critical operations, handling 16,000+ daily requests with 99.9% availability.

I led a small distributed engineering team while remaining hands-on, decomposing work, implementing core components, reviewing code, and coordinating delivery with stakeholders.

I also designed self-healing recovery mechanisms, reducing downtime by 11% and eliminating manual intervention for common failure scenarios.

I built fintech analytics and gambling reporting tools used across 19 countries.

My work included backend development and integration using .NET technologies, REST APIs, databases, and messaging systems.

This role gave me strong early experience in regulated, high-scale product environments.
