PROFILE

Geka.evk

Geka Evk worked across Mojaloop and PM4ML repositories, building robust backend features and improving reliability in distributed payment systems. He engineered distributed locking and high-availability mechanisms in Node.js and TypeScript, notably refactoring central-services-shared to use Redlock for ALS handler timeouts. In sdk-standard-components, he migrated authentication from WSO2 to OpenID Connect, enabling interoperable identity integration. Geka enhanced observability and error handling in account-lookup-service, streamlined API design in sdk-scheme-adapter, and modernized database access with Knex.js. His work demonstrated depth in API development, configuration management, and CI/CD, delivering maintainable, scalable solutions that improved system stability and developer experience.

Jun 1, 2025

June 2025 achieved reliability, performance, and developer-experience improvements across core platforms. Key features include a KnexWrapper-based database access layer with enhanced error handling, connection management, metrics, and MySQL retry logic; improved endpoint retrieval with a custom error for missing endpoint, a renderEndpoint-based resolution, and added unit tests; and Redlock-based high availability for Central Ledger implemented via Helm updates. Major fixes include routing corrections for FX transfer callback endpoints in the perf test harness and a robust getEndpoint flow in central-services communication; DIST_LOCK configuration robustness with corrected timeouts and clearer logging. The 2.11.0 release for connection-manager-api delivered updated dependencies and explicit release notes. Across all work, the team demonstrated strong TypeScript, Node.js, testing, release engineering, and distributed locking capabilities, delivering measurable business value through reduced outages, improved performance, and clearer customer communications.

February 2025

6 Commits • 5 Features

Feb 1, 2025

February 2025 monthly summary: Strengthened observability, reliability, and security across Mojaloop services. Implemented end-to-end OpenTelemetry instrumentation for streaming (quoting-service) and Kafka message processing (ml-api-adapter), enabling distributed tracing, improved logs, and richer metrics. Updated build/orb and deployment processes to support OTEL instrumentation and maintainability. Improved security by refining logging practices and exposing a safe, centralized logging configuration. Key cross-repo work included central-ledger OTEL enablement and kafka-stream updates (CircleCI orb to 1.0.53, CODEOWNERS refinement), static Logger.logLevels API exposure in sdk-standard-components, and observability-focused logging enhancements plus dependency updates in sdk-scheme-adapter. This combination reduces MTTR, improves production visibility, and enhances development velocity through better diagnostics and maintainability.

Jan 1, 2025

January 2025 monthly performance summary for mojaloop repositories. Focused on strengthening test infrastructure and simplifying production code to accelerate feedback, improve data integrity, and reduce maintenance burden. Key outcomes include a new TestCaseRunner enabling controlled test order and parallel execution in ml-testing-toolkit, plus a refactored test runner with batch execution and unit tests; a NaN handling fix in quoting-service to prevent DB errors and an update to error descriptions; removal of the logging plugin to simplify the quoting-service codebase. These changes deliver higher test throughput, more reliable test runs, and cleaner, safer production code.
