Foreks Digital
- Designed Spring Boot web services to calculate financial metrics from persistent data streams, delivering them via APIs to handle millions of daily requests from both business and end customers across diverse financial sectors.
- Decoupled app configurations from deployments using a serverless system integrated with GitLab on AWS. Utilized API Gateway, S3, and Lambda, with the entire setup deployable via AWS CDK.
- Refined six-year-old AWS Batch processes, optimized the codebase, and reduced code duplications, achieving a 60% code reduction. Transitioned these batches to Spring Boot and ensured they were deployable via AWS CDK.
- Migrated legacy JBoss and older Spring services to a serverless architecture using AWS Serverless technologies, optimizing resource use and enhancing scalability. These modernized services are now deployable via CDK.
- Upgraded all Spring Boot projects from version 2 to 3, updated JDK to 17, and also modernized all containers.
- Proactively decluttered email inboxes by reducing redundant Amazon CloudWatch alerts. Achieved this by refining log entries and adjusting filters from the past seven years, enhancing alert relevance.
- Refined and corrected GitLab CI scripts to address CI process issues. I possess the expertise to craft CI pipelines.
- Mentored junior team members and new hires, providing both theoretical and practical guidance. Engaged in pair programming sessions to foster hands-on learning and collaboration.

Experience
Foreks Cloud
Served as a back-end developer on this project, including renovating legacy services and creating new ones using Spring Boot and the required AWS tools.
The main purpose of these services is to store financial data and provide them to the clients.
I took the initiative of using a Spring Cloud Config server, which led to the decoupling of configuration from the web applications.
