Senior full-stack engineer shaping cloud-native, secure enterprise systems.
United StatesWhat I'm looking for
I’m a Senior Full Stack Software Engineer with 10+ years architecting and delivering scalable, cloud-native enterprise applications. I focus on distributed systems and REST APIs that meet strict reliability and performance expectations in fintech and SaaS.
At Credera, I architected and deployed an AWS cloud-native microservices platform processing over 10 million daily API requests with sub-200ms latency. I led the migration of a monolithic legacy application to a distributed system, reducing deployment time from 3 hours to under 15 minutes.
I build with modern web and API architectures—React for reusable frontend components, Node.js/Express for backend services, and event-driven pipelines using AWS Lambda. I’ve improved synchronization speed by 50%, advanced data-intensive reporting performance by 60%, and designed gateways and rate limiting to support massive monthly request volumes.
I’m deliberate about engineering excellence: I implement CI/CD automation (GitLab CI, Jenkins, Spinnaker), infrastructure-as-code with Terraform, and containerization with Docker and Kubernetes. I also champion security best practices (OAuth 2.0, SAML, JWT, IAM, SOC 2 Type II compliance) while using monitoring and observability (Datadog, New Relic, CloudWatch) to reduce incident impact.
