Led the architecture, development, deployment, and maintenance of scalable web applications using JavaScript/TypeScript, React/Next.js, Node.js, and PHP (including Laravel). Established frontend and backend standards, built reusable components and secure RESTful APIs, and worked with product and QA stakeholders to translate requirements into solutions. Architected and maintained cloud infrastructure using AWS along with Docker and Kubernetes, using Infrastructure as Code and automation to improve reliability. Designed CI/CD pipelines (GitHub Actions, Jenkins, or GitLab CI/CD) to automate testing, builds, deployments, and release management. Improved availability, scalability, security, and performance through caching, database optimization, load balancing, and infrastructure tuning, and implemented monitoring/logging/alerting workflows using Prometheus/Grafana and cloud monitoring tools. Managed database architecture and optimization across PostgreSQL, MySQL, MongoDB, and Redis while m

Developed and maintained full-stack web applications using React, Vue, Angular, Node.js, PHP, Laravel, and Symfony, building modular backend services and REST APIs with authentication and third-party integrations. Created responsive, accessible, and high-performance UIs with modern frontend technologies and component-based frameworks. Implemented CI/CD pipelines to streamline builds, automated testing, and deployments across environments, and containerized applications with Docker for consistent releases. Provisioned and maintained cloud resources and Linux/web server infrastructure, and optimized SQL queries, database schemas, API response times, and frontend rendering. Built automated unit, integration, and E2E tests using Jest/PHPUnit/Cypress/Playwright and performed root-cause analysis to resolve production issues. Collaborated in Agile planning, conducted peer code reviews, and supported cross-functional delivery.

Designed, developed, and maintained dynamic web applications using JavaScript, PHP, Laravel, CodeIgniter, React, and jQuery. Built reusable UI components, interactive interfaces, form validation, and responsive layouts for desktop and mobile users. Developed backend business logic, database integrations, REST APIs, and server-side functionality, including schema design, query optimization, and data migrations using MySQL and PostgreSQL. Integrated payment gateways, external APIs, email services, and authentication providers. Managed releases and feature branches using Git workflows, and maintained development/production environments with Linux, Apache/Nginx, and PHP runtime tooling. Troubleshot defects, improved code quality, and addressed performance and cross-browser/device compatibility issues while working closely with UI/UX, product, QA, and stakeholders.
