PROFILE
Mohamed Sameer
Sameer Zohan contributed to the nammayatri/nammayatri repository by building and enhancing backend features focused on vehicle service tier management, payment order processing, and tower information collection. He applied Haskell, SQL, and YAML to design robust APIs, implement idempotent transaction flows, and manage CSV-based bulk operations for driver and vehicle tiers. His work included introducing new vehicle variants, extending pass types, and improving data validation and migration reliability. By emphasizing structured data handling and maintainable architecture, Sameer enabled more flexible pricing, smoother onboarding, and accurate analytics, demonstrating depth in backend development, data modeling, and functional programming throughout the project.
