Allen Rossan

I am a Senior Full Stack Engineer with 10 years of experience designing and delivering high-performance, cloud-native applications for global clients. I specialize in React.js, Next.js, Node.js, PHP (Laravel, Symfony), Python (Django), and Rust, and focus on building scalable, reliable systems.

At ThoughtWorks I architected multi-region microservices and implemented Next.js SSR infrastructures that substantially reduced latency and improved load performance. I automated deployments with Terraform and GitHub Actions, cutting release cycles from weeks to days and improving deployment reliability.

Previously at Futurice and Endava, I developed modular design systems, integrated REST and GraphQL APIs, and improved backend performance using Redis and containerization. I also contributed to observability and SRE initiatives with Prometheus and Grafana, and mentored junior developers.

I am driven by engineering excellence and product impact, preferring remote, cross-functional teams where I can continue advancing in software architecture and technical leadership to deliver measurable outcomes.
