What I'm looking for

I’m looking for a backend role where I can scale AI-integrated distributed systems—shipping secure APIs, robust event pipelines, and reliable model-serving—while collaborating across engineering and domain experts to drive measurable performance and automation gains.

I build and scale AI-driven platforms across healthcare, fintech, and entertainment, with 10 years of experience designing distributed systems and machine-learning integrations. I specialize in Python, Java, Go, and Node.js, delivering solutions that strengthen reliability, performance, and automation.

In healthcare, I reduced end-to-end patient-data workflows from hours to under 40 minutes by developing Django and Java services, and I built TensorFlow models for diagnostic risk scoring with feature engineering collaboration. I also optimized PostgreSQL for >200M quarterly records, delivered secure REST/gRPC integrations using OAuth2 with audit logging, and deployed Kubernetes-based model-serving workloads with canary releases and automated drift checks. Earlier, I modernized fintech systems by moving from monoliths to Go and Spring Boot microservices and using Kafka pipelines for real-time fraud and authorization event processing.

GAM Tech

Mar 2018 - Jan 2022 (3 years 10 months)

Modernized a fintech platform by decomposing a monolith into Go and Spring Boot microservices, increasing deployment frequency and reducing rollback incidents. Built REST/GraphQL APIs to cut transaction-status lookup times from ~700ms to under 200ms and designed Kafka pipelines for 8–10k authorization events/sec with real-time fraud/ML risk scoring integrated via gRPC.

Junior Backend Developer

Tronsit Solutions

Jul 2013 - Apr 2015 (1 year 9 months)

Supported an enterprise analytics platform by building Flask + SQLAlchemy ETL services that replaced manual reporting workflows and reduced human-error cases. Automated validation and cleanup jobs, cutting daily data-quality issues by ~25%, and deployed Dockerized ETL workers on Kubernetes for on-demand scaling during month-end loads.
