Led design and delivery of ASP.NET Core REST APIs in C# with Entity Framework Core and SQL Server, improving API throughput ~30% via query tuning, caching, and async I/O patterns. Built and shipped new UI workflows in React + TypeScript, aligning frontend state management with backend contracts using OpenAPI/Swagger and automated client generation. Implemented secure authN/authZ using OAuth2/OIDC and token validation middleware in .NET, tightening RBAC controls and reducing security findings in release reviews. Deployed services to Azure App Service with configuration and secrets in Azure Key Vault, standardizing environment promotion and reducing misconfiguration incidents. Established CI/CD with Azure DevOps Pipelines (build, test, SAST, deploy), increasing deployment frequency while maintaining quality gates (unit + integration tests in xUnit). Introduced observability standards using Application Insights and structured logging, cutting mean time to detect/resolve production issues

Owned core platform services built on ASP.NET Core/C# and SQL Server, delivering versioned REST endpoints and domain services that supported new product capabilities without breaking clients. Designed scalable data access patterns with Entity Framework Core (plus targeted Dapper for hot paths), reducing p95 response times by ~25% through indexing and query plan optimization. Built customer-facing and internal tooling in React + TypeScript, improving usability and reducing support escalations by shipping incremental UX improvements behind feature flags. Implemented async processing for long-running workflows using Azure Functions and queue-based patterns, improving reliability and smoothing load during peak traffic. Standardized cloud deployments on Azure with Terraform and repeatable pipeline templates, shortening provisioning time from days to hours and improving auditability. Established engineering guardrails: API standards (OpenAPI), code review checklists, and testing strategy usi

Developed and maintained backend services and REST APIs using C#/.NET with relational persistence (including SQL Server), focusing on correctness, performance, and backward compatibility. Delivered frontend features for admin and operational workflows using React and modern JavaScript, coordinating API contracts and improving end-to-end user experience. Improved reliability and debuggability by adding structured logging, dashboards, and actionable alerts, reducing time spent diagnosing production issues. Implemented automated testing practices (unit and integration) and strengthened CI pipelines, reducing regressions and improving release confidence. Collaborated cross-functionally to translate product requirements into technical designs, mentoring engineers on clean architecture and maintainable code patterns.
