WORK EXPERIENCE
Head of Software Architecture
Trustly
September 2022 - February 2025
At Trustly, I served as Head of Software Architecture, leading the design, evolution, and governance of a real-time, cloud-native payments platform operating at scale across fintech, e-commerce, and gaming sectors in the U.S. My role encompassed both backend and frontend architecture, ensuring the platform’s resilience, scalability, and reliability, especially during peak events such as the Super Bowl, when system performance was mission-critical. The backend stack was primarily built on Java (Spring Boot) and deployed on AWS EKS, with infrastructure managed using Terraform and AWS CDK. Core services included: - Amazon RDS (PostgreSQL) – core transactional database - Amazon MQ (RabbitMQ) – messaging backbone - S3, Lambda, ElastiCache, CloudWatch – for storage, event processing, caching, and observability - CI/CD automation via GitHub Actions and Bamboo, ensuring safe, automated, and zero-downtime deployments One of the key architectural challenges was evolving a monolithic system originally endorsed by the founding CTO. I led the strategy to incrementally dehydrate the monolith by extracting services gradually into modular components and microservices. This allowed us to improve team autonomy and platform maintainability without compromising delivery cadence or business priorities. In addition to my backend responsibilities, I was also the assigned software architect for the frontend teams, specifically Consumer Experience and Developer Experience. These teams operated on a React + TypeScript + Node.js stack, and my role was to: - Define and enforce frontend architecture patterns, including component design, shared libraries, and API integration standards - Support developer experience through tooling, code quality standards, and performance monitoring - Work closely with engineering leads to improve codebase scalability, maintainability, and testability - Promote best practices in frontend modularization, reusable UI libraries, and CI/CD integration for frontend delivery Across both frontend and backend domains, I acted as a bridge between architecture, engineering, product, and operations, driving alignment, technical quality, and delivery efficiency. I also mentored engineers across levels, conducted architectural reviews, and championed a strong culture of engineering excellence and ownership. In summary, my work at Trustly combined hands-on cloud architecture, cross-domain technical leadership, and collaborative execution in a highly regulated, performance-sensitive fintech environment.
