At T-Bank, I work on TPay, the online acquiring platform, and am the sole backend engineer on TPay AuthBridge. I own identity and remote-identification services that help the bank and external partners authenticate users through Gosuslugi and biometric systems.
I designed and shipped a biometric identification adapter and integrated SMEV document validation. I also proposed and implemented a gateway for partner-facing endpoints and experimentation, and delivered an ESIA data-sharing adapter for a partner credit product.
On TPay Web, I identified and drove the Dolyami split-payment integration from its business case through production rollout, contributing to a 4–5% DAU increase and 2–3% conversion uplift. At Netcracker, I developed a GraphQL directive that reduced query load time by 30% and optimized Spring Batch jobs, improving throughput by 50%+.
