Professional Summary
Software Engineer with 0 years of experience focused on backend development, distributed systems and API design. Proven experience building and operating backend services using Java and Node.js, and delivering interactive front-end experiences with React and JavaScript during university and internship engagements. Hands-on expertise with PostgreSQL, MongoDB and Redis for low-latency storage patterns and consistency-sensitive workflows, plus experience deploying containerized services with Docker and automated CI/CD pipelines. Delivered authentication and rate-limiting solutions using JWT and OAuth to harden microservice boundaries. Built event-driven and asynchronous processing pipelines for dynamic pricing and inventory sync using Celery and Redis. Strong at performance tuning, observability-driven debugging with structured logging, and writing unit/integration tests to keep services reliable during frequent releases.
Technical Skills
Work Experience
- Architected an interactive 3D browser interface using React and JavaScript to render complex educational models directly in the browser.
- Improved 3D asset loading performance by 25% through deferred loading and compression strategies to reduce initial render time.
- Led design and implementation of reusable React component libraries to standardize UI patterns across multiple educational modules.
- Translated faculty instructional goals into interactive UI features and prioritized accessibility improvements for course materials.
- Implemented client-side instrumentation to capture rendering and memory metrics for reproducible debugging of complex scenes.
- Wrote unit and integration tests for core UI components to ensure stability across iterative content updates.
- Engineered RESTful APIs using Node.js to integrate third-party services for client platforms.
- Optimized SQL queries and introduced Redis caching to lower API response times by 30%.
- Automated CI/CD pipelines with Docker and Git workflows, reducing deployment failures across 13 releases.
- Integrated OAuth2 authentication flows to secure service-to-service and user authentication paths.
- Implemented automated test gates and collaborated on test engineering to raise pre-release code quality.
- Conducted performance profiling and debugging to diagnose memory and latency issues in microservices.
- Architected and implemented backend APIs in Java to handle high-volume property search requests and improve throughput under peak traffic.
- Built Node.js microservice implementing JWT authentication and rate-limiting middleware to protect user endpoints.
- Designed MongoDB schemas with geospatial indexes and compound keys to optimize location queries, reducing search latency by 87%.
- Refactored Docker-based deployment workflows and optimized CI/CD pipelines to shorten pipeline execution time and improve release stability.
- Implemented structured logging and alerting with Winston to accelerate incident diagnosis and decrease mean time to recovery.
- Applied algorithmic optimizations in backend services to reduce CPU usage per request and sustain higher concurrent traffic.
Projects
- Engineered the backend pricing calculation system using Python and FastAPI to support asynchronous, high-throughput dynamic pricing workflows.
- Optimized PostgreSQL writes and Redis caching to eliminate database deadlocks and reduce latency by 40%.
- Deployed the microservices stack with Docker and Celery to enable scalable horizontal processing during peak computational demand.
- Developed a Ruby on Rails API backend leveraging Redis for distributed locking to prevent overselling across multiple e-commerce platforms.
- Implemented PostgreSQL-based audit logging and rate limiting mechanisms to maintain data integrity and comply with third-party API constraints.
- Deployed containerized services on Google Cloud Run using Docker to achieve automatic scaling and sub-1.5-second synchronization latency under load.
- Built a scalable Java Spring Boot backend to serve retrieval-augmented generation queries against large codebases.
- Implemented PostgreSQL schema and pgvector-based vector similarity search to enable efficient code similarity queries.
- Integrated GitHub OAuth and OpenAI APIs to deliver sub-200ms AI response latency with secure token management.
