EXPERIENCE
Prismetric – Jersey City, NJ
Senior Full Stack Developer, June 2021 – Present
I built a highly scalable and intelligent HR and compliance platform designed not only for internal enterprise use, but also for external third-party users such as policy makers, auditors, and consultants.
Joined in the early build phase as a core full stack developer and contributed across backend and frontend stacks throughout the platform’s evolution.
Engineered the gradual migration from a monolithic Django architecture to a modular FastAPI-based microservices architecture by refactoring services, implementing API gateways for inter-service communication, and ensuring smooth transitions through incremental decomposition and deployment.
Architected and implemented modular microservices using Node.js and Django, ensuring independent deployment of services with seamless API-based communication.
Integrated 4 critical modules — Policy, Training, Risk, and AI Chatbot — enabling cross-module workflows and real- time compliance tracking.
Built multi-tenant support, allowing multiple organizations to manage their own users, data, and compliance configurations securely under a shared infrastructure.
Developed an AI chatbot using OpenAI APIs and FAISS, providing real-time, document-aware responses and reducing manual HR queries by 60%.
Optimized database performance using PostgreSQL with Citus for horizontal scaling, and implemented query optimizations and indexing strategies to handle high-load enterprise environments.
Integrated task queues using Celery + Redis, enabling asynchronous execution for training notifications, risk alerts, and data sync jobs.
Reduced API response times by identifying memory leaks and optimizing data serialization, significantly improving frontend responsiveness for end users.
Integrated RESTful and GraphQL APIs for clean, consistent data handling across services, enhancing flexibility for frontend developers.
Enabled real-time communication via Kafka and RabbitMQ, powering features like instant alerts for policy changes and high-risk incidents.
Wrote robust unit and integration tests using tools like Jest, Enzyme, and React Testing Library, ensuring stability and catching regressions early in CI pipelines.
Performed deep root cause analysis on production issues such as policy sync failures, chatbot latency, and incomplete training workflows — improving system reliability.
Built interactive dashboards for HR and compliance admins to track training progress, policy acknowledgment rates, and risk metrics in real time.
Implemented automated workflows, including event-based triggers to assign training on policy updates or notify users based on risk flags.
Supported cloud deployment on AWS and Azure, working with DevOps to configure environments, troubleshoot outages, and monitor performance at scale.
Collaborated with QA and product teams to reproduce complex edge cases, validate fixes, and maintain release quality throughout agile sprints.
Environment: React.js, TypeScript, Material-UI, Node.js, Django, Express.js, PostgreSQL with Citus, MongoDB, Celery, Redis, Kafka, RabbitMQ, Socket.IO, REST APIs, GraphQL, Microservices, API Gateway, OpenAI API, FAISS, AWS (EC2, S3), Azure App Services, CI/CD, Multi-tenant architecture, RBAC, Audit logging, Event-driven systems Apple – Miami, FL
Senior Frontend Developer, May 2020 – April 2021
Developed dynamic and interactive data visualizations using D3.js to present complex data in an easily understandable format.
Utilized Redux for efficient state management, ensuring the application could handle large datasets and complex interactions smoothly.
Followed best practices for component-based architecture in React.js, creating reusable and maintainable components.
Optimized frontend performance by lazy-loading components, minimizing bundle size with code-splitting, and using efficient rendering techniques.
Wrote comprehensive unit tests and integration tests for all frontend components using Jest and Enzyme to ensure high code quality and reliability.
