At YOUKI GmbH, I lead backend work for secure financial and wallet infrastructure. I owned an end-to-end project and led four engineers from requirements through production.
I implemented Blue-Green deployment with Jenkins CI/CD, eliminating around 15–20 minutes of deployment downtime and increasing releases from about twice a month to weekly. I also secured production wallets using Master Key/KEK/DEK and Shamir Secret Sharing, and integrated Web3j transaction signing.
At TID Development Co, I architected an eKYC platform with dynamic routing across external providers. Resilient Kafka consumers, retries, and fallbacks helped raise verification success under peak load from around 88–90% to 96–97%.
Earlier, I reduced duplicate transaction processing at 3F Software (Fara Fan Farzan) by around 80% and tuned Oracle SQL queries from around 8–10 seconds to around 2 seconds. My work has also included CMS modules, Java web applications, and reporting systems.
