At Merkaio, we design, build and operate complete production-ready IoT infrastructures for businesses that need reliable, scalable and open solutions - from devices in the field all the way to cloud dashboards and long-term operations. We focus on real business results, not just prototypes or point solutions. What We Do: - Unified IoT Stack: We leverage open technologies like ChirpStack (LoRaWAN Network Server), Grafana (data visualization) and ThingsBoard (IoT application platform) to create standardized, vendor-agnostic stacks that are easy to operate and extend. - Managed Operations (Ops): We operate complete IoT platforms as a managed service with SLAs - handling monitoring, updates, security patches, backups and connectivity. - Cloud Infrastructure: We build secure, scalable cloud environments (AWS, GCP, Azure or EU-based providers) tailored for IoT workloads and designed for real-world scale. - Custom Extensions & Integrations: When standard components aren’t enough, we deliver custom dashboards, data pipelines, APIs and web/mobile apps that integrate IoT data into business processes. - Hardware Integration & Life-Cycle Support: We advise, source and integrate the right sensors, gateways and controllers - from environmental monitoring to industrial telemetry. Result-Driven Outcomes: - Deliver consistent, enterprise-grade IoT infrastructure that scales from pilot to production. - Eliminate vendor lock-in by using open-source stacks you fully own. - Reduce operational complexity and risk with clear operational responsibility and SLA-backed support. - Enable real-time data insights, visualization and automation across locations and use cases - from climate monitoring to access control and remote sensing. Who We Serve: SMEs and organizations without dedicated IoT/DevOps teams, infrastructure projects in energy, agriculture, logistics and healthcare, and teams that value open technology, transparency and long-term ownership.

Oct 2023 - Present • 2 yrs 7 mos

At WZ-IT, we help companies transform their IT infrastructure into scalable, secure and efficient cloud-native systems. Based in Germany’s Ruhr region, we work with clients across Europe, Australia and the Middle East to design, build, migrate and operate robust cloud platforms. Our focus is on real business outcomes - from reducing operational costs and automating deployment workflows to ensuring 24/7 availability and GDPR-compliant hosting. What We Deliver: - Cloud Migrations & Cost Optimization: Strategic migration from hyperscaler environments (AWS, Azure, GCP) to European or private cloud stacks - often yielding significant cost savings while eliminating vendor lock-in. - Managed Services & Operations: End-to-end managed hosting of cloud infrastructure and open-source software with proactive monitoring, support and updates - freeing teams to focus on core products. - Custom Software & Platform Development: Scalable, cloud-optimized applications — including Web APIs, dashboards and IoT backends - built with modern frameworks and open-source technologies. - DevOps & Automation: CI/CD pipelines, containerization (Docker, Kubernetes) and Infrastructure-as-Code that drastically reduce deployment time and minimize manual errors. - Security & Compliance: GDPR-compliant infrastructure with secure networking (VPN, identity management, backups) tailored to enterprise-grade requirements. Proven Impact: - Automated cloud deployments reduced setup time from 4 hours to 5 minutes for a 24/7 fitness studio platform (nextGYM case). - Multiple migrations achieved up to 90% reduction in cloud operating costs. - Reliable management of critical infrastructure stacks - from Proxmox clusters to high-availability services - with continuous monitoring and fast incident response. We bridge the gap between strategic IT vision and flawless execution - empowering businesses to scale with confidence.
