About me

I architect, develop, automate, and occasionally annihilate technical debt. With years in telco, utilities and platform teams, I bridge the gap between business strategy and code reality. I believe the best solutions are invisible, boring, and extremely well documented.

Comfort zones I wander into: Java/Python/C# development, Kubernetes, observability stacks, RBAC chaos wrangling, Terraform-based governance, self-healing pipelines, SSO nightmares, and compliance puzzles. I thrive on solving "why does it work on staging but not prod" riddles and replacing tribal knowledge with living documentation.

Current role

Senior Software Engineer (DevXP) @ Veriff — Wrangling core Python libraries, improving Developer Experience in style.

Previously...

Technology Architect @ Enefit — Building resilient, compliant IT infrastructure and leading architecture for secure, automated platforms. Mentoring teams, designing ADRs, writing IaC, and guiding OT/IT convergence in style.
IT Architect @ Enefit — Bridging DevOps and platform maturity, growing observability, fixing functional sprawl
IT Architect @ Telia — Working within PCI constraints on group-scale payments systems
DevOps Engineer @ Telia — Billing systems, build pipelines
Software Developer — Contributed across stacks and domains, from backend services, frontend functionality to CI/CD, in PHP, .NET, Java, Python

Tools & strengths

Hands-on solid experience in backend development with Java (Spring Boot, JDBC, ORM), .NET, PHP, Python, TypeScript, React, Jenkins, Docker, Helm, Postgres, Kafka, Kong, Redis — whatever solves the problem
Grafana stack, CircleCI, Bamboo, OpenTelemetry, Loki, Tempo, Alloy, Pyrra
Kubernetes (on-prem/cloud), Helm, ArgoCD, K3s, Cilium, Cluster API
Terraform, Ansible, GitOps workflows, ADR governance, CI/CD sanity
NetBox CMDB, Wazuh, Teleport, OpenSearch, SSO & RBAC frameworks
Security-first architecture, platform engineering leadership, team enablement
Experience working with distributed systems and microservice architectures
Practical experience integrating systems via REST APIs
Ability to work independently and take ownership of tasks - from idea to implementation
Strong, proactive communicator in English, with a collaborative and open mindset

Problem spaces I've tackled

Developed solutions for Customer (incl user facing portals), Payments, Billing, Meterdata etc domains
Introduced observability to legacy and complex COTS applications
Maintained custom libraries (logging, CI/CD)
Configured Git platform to modern best practices with automation and policy enforcement for team-scale governance
Introduced OpenTelemetry and structured logging for multi-team observability, complete with correlation ID standards and Loki + S3 tiering
Replacing legacy ELK stack with a composable Grafana-based observability suite, with fine-grained access and scalable long-term retention
Helped design infrastructure platforms and security architecture for compliance-sensitive OT/IT converged systems with strict segmentation requirements
Improved developer onboarding by documenting complex systems and designing minimal, secure platform defaults
