I'm building backend services for Fairstone Bank's banking gateway, payment, and deposit systems using Java, Spring Boot, PostgreSQL, Kafka, OpenAPI, Python, and AWS.

Previously at MOSTLY AI, I worked across backend and frontend development on a synthetic data generation tool that used databases, cloud services, and local files to produce statistics and charts.

At Benekiva, I supported architecture, deployments, integrations, monitoring, and production operations for a multi-client insurance claims management SaaS platform. I managed AWS microservices and client deployments, integrated SAML SSO and third-party systems, and worked directly with clients on performance issues and practical solutions.

Across banking, hiring, identity management, data integration, and Android products, I've delivered Java and Angular applications, CI/CD pipelines, Dockerized services, tests, integrations, and production support. I also use AI coding agents, build MCP tools, and have evaluated a local RAG proof of concept for private-document retrieval.
