•Architected a multi-tenant SaaS client portal using Next.js 14 (App Router, SSR/SSG), TypeScript, Tailwind CSS, and a Node.js/Express.js REST API backed by PostgreSQL with Prisma ORM — onboarding 3 enterprise clients and cutting manual reporting effort by 45%. •Built an AI-powered document Q&A module using LangChain, Retrieval-Augmented Generation (RAG), OpenAI GPT-4 API, and Pinecone vector DB; applied Prompt Engineering best practices to handle 500+ concurrent queries with 60% faster document search. •Designed secure GraphQL (Apollo Server) and RESTful APIs with JWT bearer auth, OAuth2 (Google/GitHub SSO), and RBAC middleware; integrated Stripe payments, SendGrid, and Twilio — maintaining 99.9% uptime across all services. •Built Docker-based CI/CD pipelines with GitHub Actions, Kubernetes deployments on AWS ECS, Jest + React Testing Library achieving 80% code coverage, and SonarQube quality gates enforced on every PR. •Delivered Power BI-embedded dashboards and interactive charts via Recharts/D3.js, providing real-time KPI visibility that lifted product engagement scores by 30%.

● Optimized backend operations by 25% through advanced SQL query tuning, indexing strategies, and API response restructuring across PostgreSQL and MySQL databases, improving efficiency, scalability, and reducing server latency for high-demand enterprise applications. ● Implemented CI/CD pipelines with Jenkins and Docker, reducing deployment time by 40%, achieving 85% automated test coverage, and ensuring zero-downtime releases while maintaining consistent development, staging, and production environment stability across multiple applications. ● Designed, developed, and integrated 30+ RESTful and GraphQL APIs, reducing third-party integration time by 60%, accelerating feature delivery over 15 Agile sprints, and supporting seamless communication between frontend interfaces and backend services. ● Enhanced data accuracy by 25% through automated validation rules, centralized error handling, and structured logging across microservices architecture, maintaining data integrity, improving reporting reliability, and supporting robust analytics and monitoring processes. ● Engineered and deployed 10+ full-stack web applications using React.js, Node.js, and PostgreSQL, supporting over 500 concurrent users while maintaining 99.9% uptime across production environments with reliable system performance

•Developed responsive multi-tenant web apps for healthcare and education clients using Vue.js 3 (Vuex, Vue Router), PHP Laravel 8, MySQL, and Tailwind CSS — delivering Figma-to-code pixel-perfect UIs supporting 5,000+ daily active users. •Built a Laravel RESTful API backend with JWT auth, role-based permissions, and MySQL query optimization (indexes, eager loading, N+1 resolution via query logs) — reducing average page load from 4.2 s to 1.8 s and DB query count by 55%. •Implemented real-time notifications and in-app chat using WebSockets (Laravel Echo + Pusher), and integrated Google Maps, Razorpay payment gateway, and AWS S3 for media storage — improving feature adoption by 25%. •Wrote unit and integration tests with Jest and Mocha/Chai; ran automated Postman collections in CI; collaborated in Agile/Scrum via Jira, sustaining a 20% sprint velocity improvement over 6 months.

Completed advanced AI and ML coursework, developed end-to-end machine learning pipelines, implemented Python-based data processing projects, trained predictive models, and applied cloud deployment strategies for real-world analytics solutions.

Engineered software and web development projects, implemented database-driven applications, studied networking protocols, programming, and system architecture, integrating academic knowledge into practical coding and data management solutions for multiple projects.
