• Lead full-stack delivery for multiple enterprise clients using ASP.NET Core, Node.js, and REST APIs, with UIs built in React or Angular depending on client standards and timelines. • Designed and implemented microservices-based architectures on Azure and AWS, with a strong focus on API-first design, service-to-service communication, and scalable cloud-native deployments. • Built and maintained React (TypeScript) SPAs using hooks, reusable components, and API-driven state management for dashboards, admin tools, and workflow-heavy UIs. • Developed Angular applications (modules, services, reactive forms, RxJS) for enterprise clients with stricter UI conventions, handling feature implementation, performance tuning, and bug fixes. • Worked daily with SQL Server and PostgreSQL, troubleshooting production issues, debugging complex queries, resolving data inconsistencies, and optimizing slow-running queries impacting critical workflows. • Deployed and supported services on Azure App Service and Azure DevOps (CI/CD pipelines, environment configs, app settings), including troubleshooting production issues and scaling concerns. • Improved API latency by 25–40% on a high-traffic workflow by refactoring hot paths, optimizing PostgreSQL queries, and adding targeted caching. • Mentored 4–6 engineers per engagement through code reviews and pairing (front-end patterns in React/TypeScript, backend conventions in ASP.NET Core). • Leveraged AI-assisted development tools (GitHub Copilot, LLM-based coding assistants) to accelerate implementation, generate boilerplate, assist with refactoring, and improve test coverage across services.

• Owned key features for a customer-facing platform: ASP.NET Core services, Node.js integration services, REST APIs, and a React + TypeScript UI used by internal and external users. • Introduced consistent front-end state and component patterns (React hooks, shared UI components), improving delivery predictability and reducing UI regressions. • Collaborated on data-heavy features backed by relational stores, while contributing to early evaluations of NoSQL/MongoDB for flexible data capture and audit-style records. • Deployed and maintained applications on Azure App Service, configuring pipelines in Azure DevOps and supporting production releases. • Integrated internal services with ServiceNow ITSM to automate incidents and request creation for operational issues, improving response time and reducing manual handoffs. • Built secure authentication/authorization (JWT/OAuth2, roles/claims) across backend and SPA, aligning with compliance needs. • Increased release stability by adding CI checks and end-to-end tests (Cypress/Playwright), reducing production defects by ~20% over two quarters.

• Supported delivery of internal and client web applications by building features, fixing defects, and writing maintainable C#/.NET code under senior guidance. • Created UI pages and reusable components using JavaScript, HTML5, and CSS3; collaborated with QA to validate changes and reduce regression issues. • Helped implement early API endpoints and database-backed features, learning production support, logging, and disciplined debugging practices.
