Fullstack Developer at Resso.ai

Developed a visualization dashboard for an Ed-Tech application using React with TypeScript, NestJS, PostgreSQL, and Drizzle ORM, and integrated Twilio for SMS notifications, enabling 10,000+ daily student appointment reminders. Enhanced patient insights by implementing a RAG pipeline with a Python microservice and Astra DB as a vector store, replacing Llama-3.2, improving course suggestion accuracy by 20% for 300+ records. Established a multi-stage CI/CD pipeline with GitHub Actions, Docker, and AWS Fargate to achieve zero-downtime deployments. Implemented a JWT-based RBAC multi-factor authentication system for teachers and students with token expiry and refresh mechanisms to secure API resources.

Software Engineer at Snappymob

Developed scalable microservices in a monorepo using NestJS, leveraging modular design, repository patterns, decorators and dependency injection to create reusable modules enabling faster feature development. Built a real-time dashboard using ReactJS interfacing with distributed microservices. Used React Hook Form’s controlled components for dynamic filtering, Zod for validation, and TanStack Query for caching, with background refetching and optimistic updates to ensure a responsive UX. Streamlined frontend state management by adopting Zustand for lightweight centralized state across microservice-driven features, reducing Redux usage and cutting bundle size by 15%. Abstracted the data access layer with interfaces to prevent schema mutations, ensuring DB-agnostic persistence and easier future changes. Integrated DynamoDB Streams with AWS Lambda for downstream workflows and used AWS S3, and Kinesis for log streaming; improved data processing. Implemented CQRS in a payments microservice

Fullstack Serverless Developer at Kloudmate

Assisted in developing Kloudmate, a serverless monitoring app, using NestJS in a monorepo. Built a real-time dashboard with React, implemented advanced front-end features with Zustand, React Hook Form, TanStack Query, and Vite for optimized performance. Created an abstraction of the data access layer to support database-agnostic persistence. Integrated DynamoDB Streams with AWS Lambda to trigger downstream workflows and used Kinesis for real-time data. Built multi-stage CI/CD pipelines with GitHub Actions. Migrated an on-prem Neo4j data model to AWS RDS, achieving reduced latency and improved data integrity. Collaborated to document processes and improve engineering practices.

Set frontend standards for React/TypeScript and testing pyramids to maintain high quality.

Software Engineer at Snappymob

Structured a payment platform as a Turborepo monorepo to accelerate CI; implemented normalized MySQL schema with ACID boundaries and typed repositories for swappable engines. Implemented CQRS with RabbitMQ on the write side and Kafka on the query side, maintaining 20K transactions/hour with 99% uptime. Built reconciliation jobs with AWS EventBridge, SQS and Lambda, and a data ingestion pipeline (Kinesis Firehose/Lambda/S3) that reduced ingestion from 23 hours to 7 hours, processing 1.2TB at 80K records/sec. Rebuilt real-time dashboards with React 18/TypeScript, replacing polling with Server-Sent Events and optimizing rendering with memoization and virtual scrolling.
