Iwan K.

I'm a senior backend engineer and AWS-certified Solutions Architect with a Master's in Electronic Engineering and 13+ years of experience building scalable, event-driven systems using Node.js, TypeScript, and Python.

In recent years, I've worked as a consultant and cloud architect, helping organisations design, build, and scale modern cloud-native and serverless applications. My approach combines deep technical expertise with the ability to engage directly with stakeholders, uncover real needs, and design solutions that deliver measurable value.

My core technology stack includes:

• Backend: Node.js with TypeScript, NestJS, Express, and Python (FastAPI, Flask)
• Cloud & Infrastructure: AWS (AWS CDK, Lambda, API Gateway, RDS, DynamoDB, Step Functions, ECS/Fargate)
• Frontend: React with TypeScript
• CI/CD & DevOps: Docker, GitHub Actions, Infrastructure as Code

I specialize in:

• Architecting event-driven and serverless backends
• Designing secure, scalable AWS infrastructures
• Building robust APIs and integrations
• Translating complex ideas into clear, maintainable systems

I take pride in being versatile, proactive, and research-driven, always aiming to craft solutions that are elegant and efficient.
