Software Engineer | Apache Fineract Committer | GSoC 2026 Mentor

I'm a software engineer focused on building maintainable production systems and contributing to open-source software. My work spans backend development, frontend architecture, API integrations, automated testing, and CI/CD.

I work at CJ DARCL Logistics Ltd. and contribute to projects in the Apache Fineract ecosystem, including the core banking platform, its consumer-facing application, and the Backoffice UI.

• Open source: Apache Fineract committer
• Mentoring: Google Summer of Code 2026 mentor
• Core technologies: Java, Kotlin, TypeScript, JavaScript, Angular, Node.js
• Engineering interests: API design, microservices, automated testing, CI/CD, and developer tooling

Apache Fineract is an open-source platform for core banking and financial services.

Contributing to the consumer-facing application and its backend-for-frontend (BFF), with an emphasis on reliable integrations, architectural boundaries, automated testing, and efficient builds.

Selected contributions

• End-to-end testing: Playwright journeys covering registration, multi-factor authentication, accounts, transfers, loans, and authorization against a real application stack.
• Architecture enforcement: ArchUnit rules for CQRS, layering, module boundaries, and naming conventions, with a shrink-only baseline for existing violations.
• Adapter architecture: Isolating generated API clients, UI overlays, internationalization, and browser storage behind maintainable interfaces.
• Static analysis: Integrating Error Prone, SpotBugs, Modernizer, and frontend linting rules.
• CI and performance: Improving native-image builds, reducing runtime memory requirements, and strengthening automated test workflows.

Selected pull requests

• Full-stack Playwright journeys with MFA
• Enforce BFF architecture conventions with ArchUnit
• Extend adapter boundaries to i18n and Web Storage
• Add static analysis and frontend lint rules
• Reduce BFF memory requirements
• Build the BFF as a GraalVM native image

Contributing to the Angular-based Backoffice UI, focusing on frontend architecture, API integration, testing, and long-term maintainability.

Areas of contribution

• Angular and Ionic application development
• OpenAPI-driven API integration and code generation
• Adapter boundaries that isolate third-party dependencies
• Playwright end-to-end testing, including role-based access scenarios
• CI improvements, accessibility, and maintainable frontend architecture

Google Summer of Code 2026 — Mentor

I participate in the Apache Fineract community as a GSoC mentor, helping contributors work on open-source projects and navigate project development.

My mentoring interests include:

• Breaking down project goals into manageable engineering tasks
• Encouraging small, reviewable pull requests
• Promoting testing, documentation, and maintainability
• Helping contributors understand established codebases and community workflows

Working on production software and enterprise logistics systems, including backend services, frontend applications, APIs, data stores, and distributed integrations.

Engineering focus

• Developing and maintaining full-stack applications
• Building and integrating REST APIs and microservices
• Working with Kafka, MongoDB, and Elasticsearch
• Troubleshooting production issues and improving reliability
• Supporting containerized deployments and CI/CD workflows
• Delivering features through code reviews and collaborative development

• Maintainability over cleverness — prefer clear abstractions and explicit boundaries.
• Small, reviewable changes — keep pull requests focused and easier to validate.
• Testing as part of development — protect behavior and make refactoring safer.
• Resilience to change — isolate third-party dependencies and minimize coupling.
• Production-minded engineering — consider observability, failure modes, and operational constraints.
• Open collaboration — value constructive reviews, transparent decisions, and community standards.
