Software Engineer

Introduced a Kafka-based event-driven architecture to replace HTTP communication between microservices, reducing inter-service latency by 35% and eliminating 95% of transient request failures during peak load. Optimized PostgreSQL queries and indexing strategy across services using ActiveRecord and SQLAlchemy ORMs, reducing database CPU usage by 40% and improving average API response times by 20%. Used New Relic, Prometheus, and Grafana to benchmark Python (FastAPI) and Ruby on Rails APIs, driving performance optimizations that cut memory usage by 30% and CPU load by 45%. Mentored a team of 6+ engineers and implemented structured code review practices, improving lead time for changes by 35%, increasing deployment frequency by 50%, and reducing bugs by 40% quarter-over-quarter. Developed an agent using GPT-4o, OpenAI embeddings, LangChain, and Retrieval-Augmented Generation (RAG) to automate risk-related chat analysis, cutting average response time to under 5 minutes.

Built the core antifraud platform for InfinitePay from scratch using FastAPI and Faust, cutting fraud-related incidents by 30%. Designed Ruby on Rails systems for Identity Validation, Device Authentication, and KYC, reducing fraud by 25% and speeding up user onboarding by 10%. Partnered with AI/ML teams to optimize TensorFlow and PyTorch model inference pipelines, reducing latency by 40% and increasing throughput by 30%, contributing to a 5% rise in approval rates within three months. Redesigned data pipelines using Apache Kafka and optimized Redis caching strategies, lowering API latency by 25% and enhancing system resilience. Automated CI/CD workflows with GitHub Actions and Terraform, slashing deployment time by 40% while maintaining over 90% test coverage.

Built an automated UI testing suite with Python and Selenium, integrated into Jenkins, reducing release cycles from weekly to daily. Collaborated with developers to implement shift-left testing practices using Python and pytest, catching bugs earlier and decreasing regression issues by 30%. Enhanced bug triage by configuring Jira workflows and deploying Slack bots with Flask, leading to a 25% reduction in unresolved tickets within one week.

Developed firmware in C/C++ and designed electronics for IoT medical devices deployed in 100+ hospitals, enabling remote diagnostics.
