Technical Portfolio

Selected Engineering Work

I work across the full engineering lifecycle — from backend services and distributed systems to cloud infrastructure, CI/CD and production operations. My focus is building systems that are reliable, maintainable, observable and efficient.

Cloud & Platform AWS Infrastructure

AWS Infrastructure & Production Delivery

Designing and operating cloud-native environments that make software delivery more reliable, repeatable and easier to maintain.

What I work on

Infrastructure as Code for repeatable AWS environments
Containerized application deployment and orchestration
CI/CD pipelines for automated build, test and release workflows
Cloud resource configuration and operational troubleshooting
Reliability, observability and production support

Selected Impact

Reduced manual deployment and infrastructure operations.
Improved consistency between development and production.
Applied cloud optimization to control infrastructure cost.

Technologies

AWS ECS Docker AWS CDK Jenkins GitHub Actions Linux

Backend Engineering APIs & Microservices

Backend Services, APIs & Modernization

Building backend systems and APIs with a focus on clear architecture, maintainability, testability and production reliability.

What I work on

REST APIs and backend microservices
Application modernization & JavaScript to TypeScript migration
Automated testing and regression protection (Vitest/Jest)
Performance, query tuning and reliability improvements
Seamless integration between services and databases

Selected Impact

Modernized legacy JS codebases to TypeScript for strict safety.
Reduced test execution overhead by 25% through Vitest migration.
Built services that integrate cleanly with production workflows.

Technologies

Node.js TypeScript Java Spring Boot REST PostgreSQL Vitest

Green Cloud Specialty Research & Practice

Efficient Software & Cloud Systems

Applying software sustainability principles to real engineering problems — looking beyond cost alone to improve resource efficiency.

What I work on

Identifying unnecessary compute and resource consumption
Connecting software design decisions with cloud efficiency
Evaluating application and infrastructure trade-offs
Developing tools and APIs for sustainability analysis (SusAF)
Applying sustainability principles throughout software lifecycle

Selected Impact

Developed the Sustainability Awareness Framework (SusAF) API.
Evaluated architectural trade-offs affecting resource consumption.
Bridged academic Green IT research with hands-on engineering.

Technologies

TypeScript Node.js AWS SusAF Framework

Engineering Across the Stack

What connects these projects is the ability to work across boundaries. Rather than treating backend engineering, cloud infrastructure and DevOps as separate disciplines, I focus on how they work together to create reliable production systems.

Advisory & Audits

Consulting & Advisory Support

In addition to full-time engineering opportunities, I offer specialized independent consulting support for scaling engineering teams.

Eco-Friendly Cloud & Cost Audit

Deep-dive assessment of AWS environments to identify idle resource bottlenecks, optimize cross-account data transfer, and lower cloud compute fees.

Observability & SRE Overhaul

End-to-end setup of Grafana dashboards, VictoriaMetrics telemetry, Prometheus metrics, and CloudWatch alert thresholds to protect system uptime.

Enterprise Code Modernization

Zero-downtime refactoring of legacy JS applications to TypeScript, Vitest test suite acceleration, and fractional DevOps team lead guidance.

Engineering Differentiator

Sustainable Cloud Engineering

My specialization is applying software sustainability principles to real cloud infrastructure — improving resource efficiency, cloud cost, performance, and operational reliability without compromising system quality.

Why Sustainability in Cloud Matters for Enterprise

"Reducing cloud footprint isn't just about PR or compliance—it's directly correlated with code efficiency. Less CPU cycle waste means faster execution, lower server bills, and minimal carbon emissions."

Green Software Foundation

Applying carbon efficiency, hardware efficiency, and energy proportionality directly to AWS cloud architectures.

Background

About

I'm a Finland-based software and cloud engineer focused on backend systems, AWS infrastructure, and reliable software delivery.

My work sits at the intersection of backend engineering and platform engineering: I build services, automate infrastructure with Infrastructure as Code, optimize CI/CD build cycles, and help operate systems in production with end-to-end observability.

My primary technologies are TypeScript, Node.js, Java, and AWS, with production experience across Docker, ECS, Terraform, GitHub Actions, Grafana, and VictoriaMetrics.
