What I'm looking for

I’m looking for high-impact roles on teams that prioritize security, scalability, and clean code, where I can lead architecture, microservices, and CI/CD automation to cut delivery and deployment time.

I’m a Senior Software Engineer with 15+ years building banking platforms and enterprise systems, specializing in Java (Spring Boot), Python (Django), and React. In my current role as Senior Developer Engineer & Team Lead at Innteci Innovations, I designed and delivered an end-to-end card delivery system that integrates siloed applications and reduced delivery time by 70%.

I lead architecture and quality improvements across microservices, security, and automation—building Docker-based Spring Boot microservices, enabling biometric validation for instant card activation, and maintaining zero blocker vulnerabilities in production with SonarQube. I’ve also accelerated deployments by 60% through Jenkins CI/CD across DEV/QA/UAT/PROD, supported 500K+ monthly transactions with strong database design, and reduced documentation/formatting errors by 90% using Quadient Inspire workflows.
