Summary
I’m a Golang developer with experience at T-Mobile, where I worked on building APIs using GraphQL and REST. I’ve also used Java, JavaScript, Node.js, and NestJS for backend development. Most of my work has been around building reliable backend services, improving performance, and working with teams in an agile environment to get things done.
I’ve worked with microservices and containerized applications, and I’m comfortable collaborating with cross-functional teams to solve problems. I also have a good understanding of blockchain fundamentals like proof of stake and proof of work, along with public and private blockchain architectures.
I’m familiar with cryptographic concepts like hashing, encryption, and digital signatures, especially in the context of distributed systems. I’ve also explored Web3 and how it connects to modern backend and blockchain-based applications.
Overall, I enjoy building scalable, reliable, and efficient systems that are actually useful in real-world scenarios.

- Contributed to T-Cloud, T-Mobile’s internal platform on OpenShift, helping teams run and manage containerized applications more easily.
- Built backend services in Go, using both GraphQL and REST depending on what fit best for the problem
- Integrated APIs with Permit.io to handle real-time access checks between users and resources
- Helped design access control using RBAC and ReBAC to support a secure multi-tenant environment
- Developed a self-service system so users could manage roles and permissions on their own through APIs
- Worked with Microsoft Entra ID (Azure AD) for authentication, using JWT tokens to pass identity across services
- Set up SCIM provisioning to automatically sync users, groups, and roles, reducing manual work.
- Used Neo4j to model and query relationships, making access control decisions more efficient.
- Containerized services with Docker, and handled deployments on OpenShift using Helm and ArgoCD.
