Systems Architecture
Design and evaluation of complex system architectures across embedded, mobile, and cloud domains, including modular IoT systems based on ESP32, RFID, Modbus RTU, and gRPC-based infrastructure.
Android & Mobile Development
Delivery of production-ready Android and iOS applications using Jetpack Compose and Compose Multiplatform, including national-scale rollouts and medical prototype firmware.
IoT & Embedded Systems
Development of industrial firmware, serial communication drivers in C, and integration of embedded systems with web-based telemetry and analytics workflows using ESP32 and ESP-IDF.
Documentation Architecture
Design of reusable documentation architectures for platforms such as n8n, Zapier, and Make, and migration of product documentation to Git-based Docusaurus systems.
CI/CD & Automation Pipelines
Automation of multi-language OTA release workflows using GitHub Actions and Docker, enabling structured collaboration and auditability.
Programming Languages
Proficiency in Kotlin, Java, C/C++, Python, and Arduino/ESP32 for a wide range of software and embedded engineering tasks.
Frameworks & Libraries
Hands-on experience with Jetpack Compose, Compose Multiplatform, Hilt, Dagger, Retrofit, and Coroutines for modern Android and multiplatform development.
Developer Tooling
Regular use of Git, GitHub Actions, Docker, Docusaurus, Android Studio, Home Assistant, and ESP-IDF in professional and open-source projects.
Open Source Contribution
Maintenance of open-source repositories including Arduino libraries and Kotlin/Compose samples, as well as contributions to community IoT integrations and developer tooling.

Project history
Designed and implemented an open-source n8n integration, built reusable documentation architecture for n8n, Zapier, and Make, migrated product documentation to a Git-based Docusaurus system, and worked across engineering, documentation, and product strategy in a high-autonomy consulting role. Also preparing Eledo Academy, a video-based product education initiative.
Maintainer of open-source repositories including Arduino libraries and Kotlin/Compose samples. Contributor to community IoT integrations and developer tooling.
Architected modular IoT systems across ESP32, RFID, Modbus RTU, and gRPC-based infrastructure, automated multi-language OTA release workflows using GitHub Actions, and integrated embedded systems with web-based telemetry and analytics workflows.
