Multiple Payment Integration
I developed and integrated multiple payment gateways into a FinTech trading platform to support secure deposits and withdrawals.
The payment system includes payment initiation, transaction processing, payment status verification, webhook/callback handling, transaction tracking, and wallet balance updates.
I worked on integrating different payment providers through REST APIs and implemented authentication, request signing, transaction verification, error handling, and idempotent payment processing.
The system supports:
Multiple payment gateway integrations
Deposit and withdrawal processing
Payment authentication and secure API communication
Transaction status verification
Webhooks and callback handling
Payment retry and pending transaction management
Wallet balance updates
Transaction history and tracking
Failed and successful payment handling
Secure payment data processing
Background processing for payment transactions
Database and API integration using .NET and SQL Server
Technology: C#, .NET / ASP.NET Core, Web API, SQL Server, Dapper, REST APIs, Webhooks, Azure services.
Key focus: Building a reliable and scalable payment architecture that can support multiple payment providers while maintaining accurate transaction and wallet status.

ZEVA - A Fintech Experience Designed Around Everyday Money
Most finance apps focus heavily on transactions.
ZEVA explores what happens when financial management becomes part of a broader everyday experience.
The product combines:
• Payment and purchase management
• Outstanding payment visibility
• Refund and return tracking
• Shopping and selected stores
• Cashback benefits
• Card selection
• Personalized card customization
The design challenge was to bring these different behaviors together without making the experience feel overloaded.
The result is a clean, premium mobile interface where financial management, rewards, shopping, and personalization work as parts of one product experience.
Good fintech UX isn’t about adding more features. It’s about making complex financial actions feel easier to understand.

ByaheroApp — Local Delivery Web App
I developed the customer ordering flow for ByaheroApp, a delivery platform designed for local merchants. Customers can browse merchants and products, add items to a cart, enter delivery details, and place cash-on-delivery orders. I also built a merchant dashboard for viewing incoming orders and worked on the Supabase database that stores merchants, products, orders, and order items.
The project uses Next.js and Supabase. My work covered the app’s frontend, order flow, database integration, and troubleshooting across the customer and merchant views. Admin management is still in development.
