Work Experience

Full-Stack Developer

Softtrine-Oneclarity

Aug 2025 - May 2026

Owned full-stack architecture of a multi-tenant enterprise platform, designing scalable Node.js/Express.js backends and TypeScript React frontends with a strong focus on long-term maintainability, automated test suites, and extensibility. Architected Kafka-based event streaming pipelines for asynchronous inter-service communication, decoupling core services and significantly improving platform resilience and throughput under high-concurrency load. Designed and enforced a security-layered API surface: OAuth 2.0/SAML SSO authentication, input validation, rate limiting, XSS/CSRF protection, and CSP/HSTS headers — ensuring enterprise-grade compliance across all services. Built and integrated production OpenAI-powered chatbots and LLM-driven automation workflows into enterprise operations, cutting down manual effort and accelerating decision velocity for internal teams. Architected a platform-wide real-time notification system using WebSockets and RabbitMQ-backed async messaging, enabling reliable low-latency event delivery across distributed microservices. Implemented SCIM-based user provisioning with automated lifecycle management and secure token authentication, minimizing manual identity operations and improving operational reliability at scale. Designed and optimized PostgreSQL schemas and Redis caching strategies for high-traffic endpoints; configured Docker and GitHub Actions CI/CD pipelines for automated build, validation, and deployment workflows. Mentored junior engineers through design walkthroughs and pair programming; drove engineering standards and collaborated with product and platform teams to translate requirements into production-ready systems in Agile sprints.

Software Engineer

Vistaar Technologies

Jun 2023 - Oct 2024

Owned end-to-end development and production support of 15 RESTful APIs using Spring Boot; diagnosed and resolved 15 production incidents within 3 months, decreasing API failure rates by 25% through systematic root-cause analysis and hardened error handling. Drove a 40% improvement in data query efficiency by redesigning JPA/Hibernate query logic and introducing custom repository patterns on normalized PostgreSQL schemas — directly lowering backend latency under production load. Built 15+ user-facing pages in React.js/TypeScript and resolved 20+ UI performance issues, cutting page load times by 15% through targeted profiling and rendering optimization. Engineered 10 reusable React component library modules, shrinking feature development time by 35% and improving cross-team consistency; front-to-back API integration improved data retrieval speed by 30%. Practiced test-driven development with Jest and JUnit for unit and integration validation; containerized services with Docker; managed CI/CD build pipelines ahead of QC deployments.
