Rasmus Kockum
Senior Engineer & Tech Lead
I build Java backends handling 20k+ RPS, React frontends built to last, and the cloud infrastructure between them. I tune database queries, design CI/CD pipelines, and know the difference between a real microservice architecture and a distributed monolith.
How I can help ↓Three areas where I make a difference.
Senior Engineer
I write the code others avoid: high-throughput services in Java and Go, React frontends that hold up under real load, database query optimization, and infrastructure that stays up. I have tuned systems past 20k RPS and know which levers to pull, wherever in the stack they are.
CI/CD & AI Workflow Coach
I set up the pipelines, testing strategies, and review processes that let teams merge AI-generated code with confidence. If your team wants to move fast with AI without breaking production, I build the guardrails that make it possible.
Software Architect
I design systems that stay decoupled under real-world constraints. Having seen both, I know the difference between a true microservice architecture and a distributed monolith wearing microservice clothing. I have served on architecture forums since 2016, shaping technical direction at the organizational level.
Projects I have led.
Custom platform for a CNC machine company
Acting as CTO and lead engineer for a company that manufactures and sells CNC machines. Designed and built a custom platform from the ground up: an integrated CRM, e-commerce storefront, product configurator, and order management system.
Customer service platform for airlines
Built a new customer service system from scratch for airlines. Designed the service boundaries, stood up the cloud infrastructure on Azure, and led the team through delivery. The system handles agent workflows, passenger data, and real-time case management at high reliability.
Cloud native Passenger Service System
Led development of a new PSS built for high availability and performance. Designed a cloud native architecture on Azure, defined the CI/CD pipeline, and drove the team to meet strict airline industry uptime and latency standards.
Airline alliance migration in 8 months
Switched an airline from one global alliance to another, end to end. Coordinated across reservation systems, departure control, and passenger handling on a tight deadline with zero room for downtime.
Stock portfolio recommendation platform
Architected, built and deployed a platform for stock portfolio recommendations. Implemented real-time stock price updates with websockets and a React frontend.
Core banking migration to SAP
Led migration from a legacy core banking system to SAP, coordinating across multiple teams in the organization. Managed the technical integration work while keeping existing operations running throughout the transition.
Breaking out a monolith, piece by piece
Led the first extraction from a large monolithic application into independent services. The approach proved itself: subsequent extractions followed across multiple teams, cutting deployment cycles and enabling parallel feature development.
