What I'm looking for

I seek roles building scalable backend and full-stack systems, integrating AI, working with cloud-native infrastructure, and collaborating cross-functionally in fast-paced, product-driven teams.

I am a Senior Software Engineer with 8+ years building backend and full-stack systems for startups and enterprise companies. I specialize in microservices, data pipelines, and integrating AI/ML models into production services.

At FlyFin I architected and deployed Python, Golang, and Node.js microservices, designed AWS-based infrastructure (ECS, Lambda, API Gateway) with 99.9% uptime, and automated CI/CD and Terraform workflows to cut release times by 70%.

I built data pipelines and ETL workflows using Pandas, NumPy, and Apache Airflow to analyze millions of transactions and delivered real-time analytics with Elasticsearch and Kibana. I also collaborated on GPT-powered tax advisory features and AI-driven document processing with high accuracy.

Previously, I developed high-throughput APIs and event-driven systems (Kafka) at Flock Safety and improved data integration and automation at Salesforce. I value secure, performant systems, test automation, and cross-functional collaboration to deliver reliable products at scale.
