What I'm looking for

I’m looking for a role where I can own backend services and cloud-native data workflows—building scalable APIs, reliable integrations, and measurable performance in modern Java/Spring environments with strong production practices.

I’m a backend-oriented Software Engineer with strong experience building cloud-based solutions for financial companies. I specialize in Java and Spring Boot, working across SQL and NoSQL databases like PostgreSQL, MSSQL, MongoDB, and Cosmos DB, with a foundation that includes C# and AngularJS from my early full-stack and hybrid mobile work.

In my current role, I build and evolve backend services and APIs using Java 17 to support large-scale, data-driven platforms. I integrate insights generated through Databricks notebooks (Python) operating on Snowflake and Hadoop, then orchestrate reliable data workflows using Airflow and Azure Data Factory—deploying on Azure with AKS and Azure Functions, while leveraging components like Azure Blob Storage and Azure Key Vault.

Previously, I owned and maintained mission-critical integrations such as USD (ACH) transfers, prioritizing reliability, scalability, and production stability through proactive monitoring and incident resolution. I’ve also delivered end-to-end microservices in high-performance distributed systems, led a small team for a month, and contributed to platform architecture decisions—while creating event-driven and ETL solutions with Kafka and Azure-based processing.
