GIMI

GIMI

GIMI is a fintech product I co-founded and lead as CTO. Built from scratch — product strategy, architecture, engineering, and launch. This is not client work; it is my own product, shipped and maintained in production with real daily users. The same operator mindset, technical depth, and shipping discipline goes into every Malamas Devs engagement.

Challenges

• Building a full fintech product from zero with regulatory and compliance considerations
• Designing a scalable architecture that handles financial data securely and reliably
• Shipping fast while maintaining the engineering quality required for production fintech
• Leading product decisions alongside engineering — balancing user needs, business goals, and technical constraints

Solutions

• Full-stack architecture with React Native mobile, Node.js backend, and PostgreSQL — optimized for reliability
• Stripe integration for payments with proper error handling, retry logic, and edge case coverage
• CI/CD pipeline with automated testing, staging environments, and zero-downtime deployments
• Active product leadership — feature prioritization, user research, and iterative design based on real usage data
