At Sittap, I led backend development for a multi-vendor restaurant platform, delivering APIs across five applications with a team of six engineers. I also designed distributed microservices using service discovery, message queues, and database-per-service patterns.
I implemented Stripe payments for subscriptions, real-time transactions, refunds, and webhooks. By optimizing database queries, I reduced aggregation time from five seconds to 2.5 seconds.
I contributed across the frontend and backend of Sittap’s Owner Panel, Customer App, Waiter App, and Click & Collect platform. The work included KPI dashboards, NFC-based ordering, cashless purchasing, and flexible order workflows.
At Data Host, I redesigned SMS services to automate operator detection and improve profitability. I also create educational tutorials on Java, Spring Boot, machine learning, and emerging technologies through my personal project, EL-COM.
