Architecting and deploying intelligent infrastructure and AI-driven systems with a focus on scalable design, secure automation, and equitable access to educational technologies in underserved learning environments.

• Modernized a multi-rail payments gateway powering card, UPI, and QR transactions, with a focus on security, reliability, and developer experience.

• Rolled out card tokenization (Node.js/Fastify, PostgreSQL, AWS KMS) for saved-card checkout; achieved >90% token coverage in 6 weeks.

• Built token-first checkout flows with 3DS fallback, reducing PCI audit overhead and improving compliance posture.

• Strengthened UPI & QR payments with dynamic QR codes, signed webhooks, and deep-link fixes.

• Added BullMQ retries with exponential backoff and idempotent order states, cutting stuck payments by ~45%.

• Refactored reconciliation & settlements with Airflow, S3 ingestion, and PL/pgSQL, shrinking reconciliation cycles from 4h to ~20m.

• Automated merchant statements & exception reports, reducing payout disputes and write-off leakage.

• Implemented end-to-end observability (OpenTelemetry, Grafana, circuit breakers), authored runbooks, and enabled canary releases; MTTR improved from 90 to 18 minutes.

• Shipped multi-language SDKs (Node, Java, PHP) with GitHub Actions + OpenAPI docs, cutting partner integration time by ~40%.

• Standardized error codes & webhook payloads, lowering API support escalations by ~35%.

• Embedded compliance & security controls (TLS 1.2+, KMS/Vault rotations, CI scans), closing PCI/ISO audit findings.

• Improved developer experience with CI/CD pipelines, Postman collections, and sample apps, enabling faster partner go-lives.

• Contributed to developing and deploying a custom CMS for the university’s official website using Next.js, React.js, and Material UI, enabling dynamic content updates for 8,000+ students and staff.

• Built secure backend services with Node.js and MySQL2, implementing JWT authentication and OAuth 2.0, and supporting maker-checker workflows for multi-role content management.

• Integrated a 2-layer content approval system, automating publishing workflows by 70%, improving content accuracy and editorial traceability.

• Improved performance by optimizing data models and frontend components, reducing load times by 40% and streamlining admin updates by 90%.

• Deployed the project on a CentOS Linux server using PM2 for process management and Apache as a reverse proxy, ensuring stable performance in production.

• Tested backend routes and workflows with Postman and Supertest, ensuring secure authentication, proper versioning, and reliable data flow across roles.

• Collaborated with a cross-functional team of 4, contributing to API integration, route management, CMS admin interface, and deployment coordination.

🔹 Initial groundwork for the university's CMS—architectural planning and early backend structuring—began during these internship, evolving into a full-fledged development later.

• Upgraded the Faculty Appraisal Management System to align with updated institutional policies, reducing manual processing by 60% across departments.

• Enhanced backend functionality using PHP and MySQL, adding new data structures and improving report generation for senior management dashboards.

• Refactored API communication logic using RESTful protocols, improving data flow and scaling appraisal record handling by 60% across the university network.

• Improved frontend–backend interaction using vanilla JavaScript and jQuery, enhancing form validation, UI responsiveness, and appraisal workflow accuracy.

• Collaborated with internal stakeholders to gather new system requirements and deliver iterative updates aligned with university HR policies.

• Led and coordinated the development of 5+ university websites using PHP, JavaScript, and CSS, contributing to frontend architecture, backend scripting, and live deployment.

• Refactored and modularized common features like auth, blogs, and user dashboards, creating reusable codebases that reduced development effort by 70% across projects.

• Managed a GitHub-based collaborative workflow across a 20+ member student team, facilitating version control, code reviews, and continuous improvements.

• Maintained the club’s public GitHub organization, showcasing open-source contributions and delivering reliable digital interfaces for student and departmental initiatives.
