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.
