À propos de moi
I build secure, high-performance backend systems for fintech and payment platforms handling high transaction volumes. Experienced in modernizing large-scale Java systems (100+ modules) and developing microservices processing millions of transactions under PCI-DSS compliance. I’ve reduced API latency by 30% and improved cache performance by 25% through optimization. Skilled in Kafka, real-time pipelines, tokenization, and encryption, I design scalable systems that perform reliably under pressure without downtime.... Plus d’infos

I build and optimize backend systems for fintech and payment platforms that need to handle high transaction volumes securely and reliably. I’ve helped modernize large-scale systems (100+ modules), migrate legacy Java applications, and deliver microservices processing millions of transactions daily under PCI-DSS standards. I focus on results: reduced API latency by 30%, improved cache performance by 25%, and eliminated critical security risks while achieving full CSP compliance. I’ve implemented tokenization, encryption, and real-time Kafka pipelines to ensure secure, seamless data flow across distributed systems. I also design scalable features like multi-currency engines, corporate card hierarchies, and high-volume data pipelines, ensuring systems perform under pressure without downtime.
