As part of Payfit’s Internal Developer Platform team, I managed the Testing On Demand team while maintaining a hands-on role as a platform engineer. This dual focus allowed me to blend technical expertise with team leadership to deliver impactful solutions across the organization.- Team Management: Led the Testing On Demand team, ensuring the platform remained a critical tool used by 80% of Payfit’s technical teams across squads and tribes. Oversaw team productivity and fostered alignment with organizational goals while mentoring team members in debugging and application development.- Platform Engineering Expertise: Designed and enhanced platform workflows and components to optimize developer productivity. See below for a detailed description of my technical contributions, including CI/CD optimization, infrastructure transformation, and developer enablement.- Leadership & Collaboration: Provided strategic direction and hands-on support to both team members and end users, ensuring the seamless operation of tools like Kubernetes, ArgoCD, Helm, and Terraform. Evangelized platform best practices to expand adoption and improve efficiency across technical teams.

As part of Payfit’s Internal Developer Platform team, I specialized in designing and enhancing platform components and workflows to optimize developer productivity, streamline CI/CD processes, and promote autonomy within engineering teams.- CI/CD Optimization for Monorepo: Implemented workflows to build and test only changed components, leveraging the NX build system and custom scripts to orchestrate processes on CircleCI. This approach reduced build times and resource usage, enhancing efficiency across teams.- Infrastructure CI/CD Transformation: Evaluated tools, managed vendor contracts, and integrated Spacelift into Payfit’s ecosystem. Transitioned infrastructure management from a domain-vertical approach to a microservice-centric model, empowering developers to take ownership of their codebase and deployment orchestration under the "you build it, you run it" philosophy.- Mentorship & Enablement: Provided extensive guidance on Kubernetes, ArgoCD, Helm, Spacelift, and Terraform usage, enabling developers to achieve autonomy over their systems. Supported teams in reducing friction and increasing delivery output by aligning tools with best practices.- Platform Component Development: Designed and deployed key infrastructure components using Terraform and AWS Serverless Application Model (SAM). Simplified the management of critical elements like secret management, Lambda functions, IAM roles/policies, and more. Enhanced observability with Datadog, enabling better monitoring and troubleshooting across the platform.- Project Management & Evangelism: Led migration projects and drove platform adoption among less technical users, expanding the reach and usability of the platform. Evangelized platform capabilities, onboarding new teams and fostering alignment on best practices.

As part of Payfit’s Developer Experience team, I specialized in designing and enhancing tools and platforms to optimize developer productivity and streamline workflows. My work focused on improving the Testing On Demand platform, a critical tool adopted by 80% of the technical team across multiple squads and tribes, driving efficiency and reducing friction in the developer journey.- Platform Engineering: Completely redesigned the Testing On Demand platform, implementing industry standards such as Helm, ArgoCD, and Kubernetes for deployment. Developed a robust API using NestJS and TypeScript, and ensured reliability through extensive unit, integration, and E2E testing with Jest and SuperTest. Monitored platform performance using Datadog, providing visibility into both application and deployment pipelines.- Cross-Functional Support: Provided end-user support to technical teams, helping developers debug and improve microservices (API, BFF, UI, Lambda, database). Conducted training on Helm, ArgoCD, Kubernetes, and platform integration to ensure alignment and understanding across teams.

As part of Payfit’s Jetlang Platform team, I specialized in shaping, enhancing, and maintaining a low-code platform critical to payroll and HRIS solutions, supporting over 10,000 clients across Europe. With a strong focus on platform engineering, I led impactful initiatives in CI/CD optimization, cloud-native solutions, and cross-functional collaboration.- Platform Engineering: Led the development and debugging of AWS Lambda functions for official government document generation. Rewrote the entire codebase to align with best practices, significantly improving maintainability, monitoring and debugging efficiency.- CI/CD Optimization and improvement: Achieved reduction in pipeline runtime and credit consumption by streamlining workflows across CircleCI and GitHub as well as introducing dual system compilation for both Flow (legacy) and Typescript during the code base migration.- Cross-Functional Collaboration: Acted as a bridge between product builders, customer success teams, and platform engineers, helping in issue resolution and enabling scalable feature development. Also, created detailed documentation to empower internal teams and improve autonomy.- Project Management & Leadership: Led system and feature migrations, ensuring smooth transitions and designing scalable solutions for squad-level implementation. Also, facilitated tribe-wide discussions to address critical platform issues, driving alignment on improvements and long-term strategic goals.
