– Led a production-ready solar roof configurator and automated quotation platform development using Next.js frontend and Express.js backend. – Engineered the dynamic roof configuration interface with React Hooks, Tailwind CSS, and Framer Motion, enabling real-time interactive visualization of complex roof layouts. – Resolved a performance-critical calculation bottleneck where large roof geometries caused server response time delay, by rewriting Node.js processing logic, implementing worker threads, and caching intermediate results in Redis. – Overcame integration challenges with three legacy ERP/CRM backend systems using Restful APIs and custom adapters, synchronizing product catalog, pricing rules, and customer data without disrupting active sales processes. – Integrated client-side inference using pre-trained TensorFlow.js models, automatically suggesting optimal solar tile layouts based on pitch, orientation, and energy consumption history. – Implemented responsive, interactive frontend components using Context API, Styled Components, and React Query, providing seamless cross-device experience. – Automated generation of PDF quotations with Puppeteer and pdf-lib, reducing manual errors and accelerating proposal delivery for sales teams. – Secured authentication, authorization, and GDPR-compliant handling of sensitive user data using JWT, bcrypt, and Express middleware, ensuring safe production deployment. – Collaborated with UX design teams using Next.js SSR/ISR, React Testing Library, and Lighthouse audits, achieving high accessibility (WCAG-compliant), fast load times, and maintainable code.

– Delivered a scalable AI-enabled digital ecosystem using React and NestJS, deployed on cloud infrastructure managed via Terraform, streamlining enterprise workflows and increasing learning efficiency. – Engineered interactive dashboards and adaptive learning interfaces with React Hooks, Redux, Material-UI, and D3.js, enabling real-time visualization of employee competencies. – Secured complex multi-role access control and permissions by implementing NestJS Guards, JWT, and RBAC, preventing unauthorized data access across multi-tenant environments while maintaining GDPR compliance. – Integrated a PyTorch-based optimization service via NestJS microservices to automatically prioritize tasks and suggest process improvements, increasing operational efficiency. – Orchestrated backend GraphQL and REST APIs to synchronize legacy ERP and HR systems, ensuring real-time updates of employee profiles, training records, and workflow data. – Implemented real-time notifications and analytics engine with WebSockets and Redis Pub/Sub, delivering live alerts, usage insights, and KPI dashboards across the organization. – Implemented Linux-based CI/CD pipelines with Docker and Kubernetes, ensuring reliable and compliant production deployments.

– Delivered a role-based reporting and analytics platform using React.js and Node.js, allowing users to generate dynamic reports, track key business metrics, and customize dashboards based on access level. – Integrated WordPress CMS into the platform for content management, allowing editors and managers to update blogs, marketing pages, and documentation dynamically without backend deployment. – Enhanced dynamic frontend dashboards with React.js components, Redux state management, and Axios API calls, implementing real-time filtering, sortable tables, and interactive charts, improving interface responsiveness and user productivity. – Orchestrated seamless REST API and WebSocket connections between backend, frontend, and WordPress, enabling live notifications, interactive dashboards, and real-time content updates. – Implemented performance optimization and monitoring using PostgreSQL indexing, query optimization, server-side caching, and Node.js profiling, reducing page load times and maintaining high uptime.

– Built a scalable hotel and travel booking web application, supporting accommodation search, availability checks, and end-to-end reservation flows. – Designed SEO-friendly, server-side rendered interfaces with EJS templates, reusable partials, and Express.js routing, delivering fast page loads and optimized booking journeys. – Implemented core booking, membership, and subscription logic in Node.js, using MySQL transactions and relational schemas to ensure data consistency across reservations, cancellations, and upgrades. – Integrated secure online payment processing via Restful APIs and third-party payment gateways, handling confirmations, refunds, and failure recovery for real-world booking scenarios. – Optimized system performance and reliability through MySQL indexing, query tuning, server-side caching, and Node.js profiling, ensuring stable operation during peak traffic periods.
