What I'm looking for

I’m eager to continue my journey as a Software Developer. I want to build scalable web apps and real-time data/IoT pipelines, collaborate in teams, and keep learning—while delivering reliable APIs, automation, and maintainable architecture.

I bring over 7 years of hands-on experience developing web applications and data-intensive systems, using a diverse stack anchored in ASP.NET, Django, JavaScript, and MongoDB. I’m especially motivated by work that blends software engineering with real-world data, performance, and reliability.

As Technical Lead on the DIWA Digital Twin Project (Finland’s National Hydrologic Digital Twin), I designed hybrid ingestion for real-time IoT telemetry and large-scale researcher uploads, implemented an MQTT-to-Kafka bridge with metadata enrichment, and built an automated validation framework for sensor vocabulary standardization. I also delivered an Airflow-based WaterML2.0 transformation pipeline with statistical quality control and strong FAIR principles and provenance tracking.

In my CTO and Team Lead role, I spearheaded a Django + MongoDB backend and a React (TypeScript) frontend, built Django REST and Swagger APIs, and streamlined delivery with Jenkins CI/CD. I also led infrastructure-as-code using Kubernetes, Terraform, and Ansible, while supporting Digital Twin projects with SCADA integrations and protocols such as Modbus, OPC UA, MQTT, and DNP3.

I’ve also contributed as a blockchain and backend developer, optimizing crypto-related services and APIs, improving database performance, and strengthening CI/CD for dependable deployments. I’m a natural learner who enjoys sharing knowledge, and I want to continue as a Software Developer building maintainable, scalable systems that perform under real constraints.
