01 / Experience

Engineering across banking, healthcare and product teams.

—

Innovance / Odeabank

Full-Stack Developer

Worked in the SWAT team supporting multiple banking domains, taking responsibility for both greenfield development and high-impact improvements across web and mobile.

Cross-domain product delivery

Built and improved products for open banking, equity and fund trading, branch operations and management-level workflows used by bank employees.

Frontend platform modernization

Introduced Tailwind CSS and Shadcn UI into the bank's frontend culture and turned the existing foundation into a reusable component system. The approach accelerated new project starts; API Management reached its final version in 1.5 months, with Timesheet and investment products built on the same foundation.

Investment system reliability

Redesigned socket connection management for equity and fund trading with retry, connection-state checks and subscription mechanisms. This helped the bank move away from its legacy Forex SDK and adopt its own investment infrastructure.

Open banking flows

Contributed to the web and mobile delivery of Send Money, Bring Money and Request Payment capabilities, working directly on the bank's money-transfer experience.

Shared web and mobile architecture

Developed mobile and web applications from a single React Native Web codebase and built Nest.js Backend for Frontend layers for efficient, controlled data flow between interfaces and banking services.

Internal banking applications

Delivered numerous React and Tailwind CSS applications for branch and management teams in addition to customer-facing mobile experiences.

Casemice

Software Developer

Built web and mobile products for healthcare and pharmaceutical companies, gaining broad ownership across product architecture, implementation, delivery and team coordination.

End-to-end product ownership

Delivered numerous web and mobile applications, owning many of them from initial architecture through production release and long-term iteration.

Developed the Next.js web and Expo mobile clients of a healthcare and pharmaceutical training product over approximately two years. Managed store releases and implemented deep links and universal links.

CaseTree & Docmaze · Patient simulations

Built separate Next.js applications for patient-treatment simulations used in pharmaceutical product presentations, with multiple web clients sharing a common backend.

İnme 112 · Stroke response

Developed a React Native / Expo mobile application for a pharmaceutical company to help ambulance personnel locate the nearest appropriate hospital for stroke cases.

Engineering leadership

Led a three-person software team for approximately one year, coordinating task allocation, progress tracking, code quality and delivery processes.

Mobile release operations

Managed Apple App Store and Google Play release workflows end to end, including CI/CD, deep-link and universal-link integrations for production applications.
