Backend lead for high-load payments, distributed systems, and legacy modernization.
I help engineering teams make production systems calmer, releases faster, and delivery more predictable, especially when the platform is business-critical and the team is compact.
- Stabilizing legacy backend services and reducing production incidents.
- Designing payment-processing architecture, REST APIs, and high-load distributed systems.
- Improving CI/CD, release discipline, and engineering workflows.
- Refactoring backend services without stopping delivery.
- Building PCI DSS/GDPR-aware payment, 3DS, anti-fraud, and incident-response integrations.
- Applying AI tools to code review, refactoring, test generation, documentation, automation, and incident analysis.
- Mentoring compact teams and making engineering work more consistent under real constraints.
