Full Stack Software Engineer with 3+ years of experience building production web applications serving 250+ clients. I specialize in React, TypeScript, Node.js, and Python with deep expertise in REST/GraphQL API design, PostgreSQL/MySQL databases, and AWS cloud deployment. I've built real-time dashboards with D3.js and WebSockets, implemented role-based access control with OAuth2/JWT, and led a monolith-to-microservices migration on Kubernetes. My work consistently delivers measurable results — 99.2% API uptime, P95 latency under 180ms, and 92% test coverage. I ship clean, well-documented, production-ready code with CI/CD pipelines, and I'm comfortable owning projects end-to-end from architecture through deployment. MS in Computer Science, SUNY Binghamton.

Software Engineer II at Cognizant
June 1, 2022 - December 1, 2023
Led decomposition of a monolithic visualization platform into microservices using Python/FastAPI, Node.js, and React on Kubernetes, increasing deployment velocity by 45% and reducing release downtime for 250+ clients. Designed real-time diagnostics dashboards using React, TypeScript, D3.js, and WebSockets via FastAPI to improve troubleshooting accuracy by 30% and enable self-service monitoring for 250+ clients. Engineered REST and GraphQL APIs with Redis caching, circuit breakers, and exponential backoff, reducing P95 latency from 480ms to 180ms while maintaining 99.2% uptime under load. Provisioned multi-region AWS infrastructure with Terraform and Ansible (EKS, RDS, ALB), integrating Grafana and Prometheus with ML anomaly detection to reduce infrastructure drift by 33%. Led CI/CD automation via GitHub Actions and Docker multi-stage builds, mentoring 3 junior engineers on OOP, unit testing, and Agile/Scrum; reduced image size by 25% and release cycles by 40%.
Software Engineer I at Cognizant
December 1, 2020 - May 1, 2022
Developed React dashboards with D3.js, Redux, and WebSocket integration, achieving sub-500 ms updates and reducing operator reaction time by 28%. Streamlined REST and GraphQL services with Node.js and Python backed by PostgreSQL and Redis; applied request batching, connection pooling, and cache invalidation to reduce median response time from 220 ms to 120 ms. Architected event-driven microservices in Go with Kafka and idempotent consumers, tuning backpressure and retry policies to cut message replays by 38% while sustaining 15,000 msgs/min throughput. Optimized Python services on Django and Celery by eliminating N+1 queries, reducing P95 database latency by 35% and batch windows from 40 to 26 minutes. Owned security hardening of OAuth2 API gateways on AWS (ALB, WAF, Secrets Manager) with RBAC and AI-powered threat detection, reducing unauthorized attempts by 60%.
