Designed and delivered cloud solutions for client engagements in e-commerce, music licensing, AI services, and SaaS platforms on AWS and GCP.

Selected projects:

- Car Pulse Tracker (2026) is a SaaS platform that generates verified vehicle health reports for Tesla owners and used car buyers. Users connect their e.g., Tesla account, select a report tier, pay securely, and receive a multilingual PDF report covering battery health, charging history, warranty status, and 250+ vehicle data points pulled directly from the Tesla Fleet API. Built with FastAPI, Vue 3, and deployed on Google Cloud.

- AI concierge (3 clients, 2025–2026): Customer-facing widget using OpenAI and Claude, deployed on AWS with Hostinger-hosted frontends with Infra handled using Terraform, Docker.

- Infrastructure renewal (Taiqa Digital, Finland, 2023–2024): Set up the Scrum team and DevOps ways of working, then rebuilt the delivery setup for a multi-site WordPress environment (40+ client sites). Introduced a Git-based workflow, PR reviews, CI/CD, and OAuth2 authentication, along with a new automated IaC platform setup supporting both AWS and GCP.

S-Pankki | System Architect

Finland, Remote | Jan 2024 - Jun 2025

- Designed with the team a centralized logging and observability architecture across Azure and Splunk (operated on AWS). The project timeline was aligned to achieve regulatory compliance ahead of DORA's applicability in January 2025. Architected integration patterns for onboarding multiple source systems via e.g., Azure Event Hub and Confluent Kafka, including sink and source connectors. Worked with business stakeholders, bank architects, and IT vendors through security/compliance reviews, handling the cutover planning and securing the resource availability, drafting the production rollout, and ensuring a proper handover to the client.

Co-founded and bootstrapped Costa Hype Studio with my partners, working on product development, market validation, and funding opportunities over a nine-month period. Despite several attempts, we were not able to build a sustainable business around the products.

Worked as Salesforce Enterprise Architect in Elisa’s large-scale telecom transformation program in Finland. My role included discovery workshops, solution blueprinting, documenting integration and data flows, and supporting delivery teams throughout the design and handover phases.

I also worked with stakeholders and vendors across several parallel workstreams.
