Selected work
Real work from design to production.
Each project solves a different problem: mobile financial education, on-prem financial intelligence, or high-traffic platform infrastructure. Detail pages cover the problem, approach, and production architecture.
01 · Mobile product · Financial education
Kapalıçarşı
A financial education app that combines live market data, virtual portfolio management, gamification, and community competition in one mobile experience.
- Problem
- Scattered resources and passive content made it hard to practice live markets without putting real money at risk.
- What we built
- We designed and built an iOS app end to end, linking live market data to a virtual portfolio and turning learning into repeatable practice through gamification and leaderboards.
- Technical scope
- SwiftUI · Go · Supabase · PostgreSQL · real-time market data · virtual trading engine
- Outcome / product value
- Live on the App Store: users trade at real prices with virtual capital and track portfolio performance over time.

02 · Financial intelligence · On-prem
Fintera
An on-prem platform that turns financial data into reporting, consolidation, and AI-assisted executive insights without sending data outside the company.
- Problem
- Consolidated financial data arrived too late, reporting stayed manual, and cloud AI tools required sensitive data to leave the company.
- What we built
- We built an on-prem platform that keeps data in-house, combining an AI assistant, anomaly detection, and reporting in one interface.
- Technical scope
- React · TypeScript · PostgreSQL · on-prem deployment · AI/LLM integration · reporting layer
- Outcome / product value
- Finance teams can query data in natural language and surface anomalies early — without sending data outside the organization.

03 · Platform · Event ticketing
Event Ticketing Platform
Production-grade event ticketing platform with real-time seat reservation, interactive venue maps, payments, and CMS.
- Problem
- Peak on-sales created seat conflicts, slow checkout, and operational friction around complex venue layouts.
- What we built
- We brought event discovery, an interactive venue map, real-time reservation, payments, and CMS into one production platform.
- Technical scope
- Go · NestJS · Next.js · Redis · Kafka · PostgreSQL · real-time reservation
- Outcome / product value
- Organizers manage events and inventory from one place; customers pick seats on a visual map and complete purchase in one flow.
