Senior Software Engineer

I developed and maintained backend microservices from scratch, integrating third-party services and implementing correlation-ID propagation to enable end-to-end distributed request tracing. I established role-based development workflows and staged feature rollouts from development through production.

I built and owned Jenkins CI/CD pipelines covering builds, SonarQube quality gates, artifact management, and automated Kubernetes deployments. I also built Scala pipelines for converting PBF/OSM and GeoJSON geospatial data into an internal map model across datasets of approximately 12 GB.

I addressed malformed and incomplete source data, international address-rule edge cases, schema migration requirements, and robust logging and exception handling. I created validation tooling to compare map-compilation outputs and detect discrepancies before production release.

I diagnosed N+1 query issues and rewrote inefficient database queries, reducing API response latency by 14% for production clients. I developed new backend features and integrations with external APIs and third-party services.

I created an internal automation tool that transitioned Kanban tasks based on merge-request status changes, removing manual status tracking. I supported 15 production microservices in an on-call rotation, resolving live incidents and collaborating with QA on release validation.

I wrote unit, microservice, and end-to-end tests, maintained technical documentation, and created SQL materialized views for business analysis.

I built automated REST API test suites in Postman covering complete CRUD lifecycles.

I tested mobile, web, and desktop applications to validate product functionality and API behavior.

I automated web and mobile test suites using Selenium and Appium.

I performed load and stress testing with JMeter across mobile, web, and desktop applications.

I supported banking applications and troubleshot web and desktop systems.

I used SQL-based data analysis to identify operational issues and support process improvements.

I provided production support for banking applications and collaborated with developers on system fixes.

I administered the client-bank system and helped maintain reliable day-to-day operations.
