• API Development: Build and maintain robust APIs that power integrations across our platform and with customer systems.
• Code Excellence: Write high-performance, reusable, and maintainable code following OOP, SOLID, and SOA principles.
• Performance Optimization: Optimize applications for speed, reliability, and scalability under real-world financial-grade workloads.
• Quality Ownership: Own the quality of what you ship — unit tests, automated UI tests, and code reviews are part of the job, not an afterthought.
• Front-End Collaboration: Work with HTML, CSS, and front-end tools to adapt templates and enhance user experience where needed.
• Continuous Improvement: Contribute to development processes, tooling, and team productivity — we’re always leveling up.

• Bonus Points: Background in financial or payment systems; experience with caching, optimization, and performance tuning.
• Mindset: Innovative, detail‑oriented, and proactive — someone who brings ideas to the table, not just code.
