About me
SDE 2 at a large multinational tech company (promoted within a year). I build complete products end to end: frontend, backend, database, deployment, and monitoring, owned by one engineer from idea to launch. Frontend: React, React Native, TypeScript. Backend: Spring Boot / Java (and Python), PostgreSQL, Kafka, Redis. Infra: Docker, Kubernetes, AWS, Ansible, CI/CD, plus monitoring with Grafana, Prometheus and OpenSearch/ELK. I also build and integrate custom chatbots. My focus is software engineering and product delivery, not AI/ML modeling. Chatbot builds and integrations are in scope.... Read more

Zscaler • Full-time

Feb 2025 - Present • 1 yr 9 mos

Full-stack software engineer with hands-on experience building scalable, cloud-native applications end to end — from frontend and backend to deployment and ongoing maintenance. At Zscaler, I own a complete application from scratch, re-architecting a monolithic system into scalable microservices and optimizing for performance, scalability, and reliability. I build clean, responsive UIs with React and robust backends with Spring Boot, using Kafka for inter-service messaging and Redis for caching. I design PostgreSQL database schemas (tables, relationships, and indexes) tailored to real access patterns, and containerize and orchestrate services with Docker and Kubernetes, deployed and maintained on AWS. My background also spans SRE and DevOps: monitoring production systems with Grafana, Prometheus, and OpenSearch, recovering services during outages, and automating provisioning with Ansible to improve consistency across environments. What I offer clients: - Full-stack web development (React + Spring Boot) - Microservices architecture and monolith-to-microservices migration - REST APIs, Kafka messaging, and Redis caching - PostgreSQL database design and optimization - Docker & Kubernetes containerization and AWS deployment - CI/CD, monitoring, and reliability engineering I focus on writing clean, maintainable code and delivering reliable, well-architected systems that scale.
