What I'm looking for

I seek a senior back-end role building secure, high-scale payment or data platforms in collaborative, cross-functional teams, with ownership of CI/CD, testing, and opportunities to apply ML/NLP to deliver measurable product impact.

I am a senior back-end engineer with hands-on experience building large-scale, secure user systems and payment platforms. I led a team to design wallet and card-binding processes, introduced token-based secure storage for hundreds of millions of password records, built a user security information management system serving over 100 million customers, and implemented CI/CD pipelines that reduced deployment time from 2 hours to 15 minutes while improving incident resolution speed by 70%.

I hold degrees in Artificial Intelligence and Computer Science and have published work on spatiotemporal trajectory representation learning. I build practical ML/NLP and data solutions—using tools from Python, TensorFlow, PyTorch and Julia to Apache Spark—and have driven measurable improvements such as a 3% accuracy gain on RNN+Attention models and a 65% reduction in ETL job runtime.
