✔ IoT Solution Leader | Leading a team of 220+ engineers ✔ 11+ Years in connected products | End-to-end IoT development ✔ Hardware + Firmware + Cloud Expertise Drop me a message with “DISCOVERY” - we’ll run a free discovery session and turn your idea into a clear architecture, timeline, and execution roadmap while avoiding costly mistakes early on. I lead a 220+ engineer team specializing in end-to-end IoT development – from early discovery and architecture to prototyping, production preparation, and long-term product evolution. Over the last 11+ years, I’ve been involved in building connected solutions that combine embedded systems, electronics, firmware, cloud platforms, and user apps (web, mobile, desktop). My role is focused on bridging business goals with engineering reality: helping teams validate ideas, select the right architecture, reduce technical risks, and build products that can successfully move from prototype to production. Core expertise: • IoT system architecture Designing complete connected ecosystems: devices, communication layers, cloud infrastructure, data flows, APIs, and user applications. • Embedded systems & firmware MCU/MPU-based development, RTOS, embedded Linux, device drivers, hardware communication protocols, low-power optimization, OTA updates. • Hardware development & prototyping Electronics design, schematics, PCB development, hardware bring-up, testing, validation, and preparation for mass production. • Connectivity & communication BLE, Wi-Fi, LoRaWAN, LTE/cellular, MQTT, sensor integration, and reliable device-to-cloud communication. • IoT cloud platforms AWS IoT, device management, telemetry pipelines, real-time monitoring, analytics, and scalable backend architectures. • Connected applications Web dashboards, mobile apps, desktop applications, admin portals, device management platforms, and third-party integrations. Typical IoT products I work with: • Industrial IoT & Industry 4.0 Connected machinery, predictive maintenance, industrial automation, sensor networks, and remote monitoring. • Smart Home & Building Automation Connected devices, automation platforms, energy management, and intelligent control systems. • Healthcare & Wearables Connected medical devices, monitoring solutions, wearable ecosystems, and compliance-focused development. • Energy & Infrastructure Smart metering, energy monitoring, telemetry systems, and remote control solutions. • Location-based products GPS tracking, asset tracking, fleet monitoring, and safety-focused connected devices. • Robotics & Drones UAV/UGV/UAS platforms, telemetry, control systems, and autonomous solutions.

Why clients work with me: • Strong industrial and commercial product development experience I work with complex products where reliability, scalability, security, and real-world constraints matter. • Ability to handle both hardware and software challenges IoT success depends on how all system components work together - not isolated development tasks. • Clear communication and structured development process Transparent milestones, technical documentation, predictable execution, and clear ownership at every stage. • Focus on practical solutions I help teams avoid unnecessary complexity and choose architectures that fit actual product goals. • Long-term support mindset Project scope for reference: Phase 01 – Definition & Architecture: $15k–$25k Discovery, requirements analysis, system architecture, technology selection, and roadmap creation. Phase 02 – Prototype & Validation: $35k–$120k Hardware prototypes, firmware, cloud infrastructure, applications, testing, and product validation. Phase 03 – Production Readiness: $60k–$250k+ Production optimization, manufacturing support, certification preparation, scalability improvements, and deployment. My approach: I don’t start with coding. I start by understanding the product vision, business goals, technical constraints, and future scaling requirements. The goal is to create IoT systems that work reliably in real-world conditions, avoid expensive redesigns, and provide a strong foundation for future growth. If you’re building a connected product involving hardware, firmware, cloud, or device management - feel free to share your idea. I'm ready to help evaluate the technical approach and identify the most practical path forward. Worth a chat?

As a React Developer and Full Stack Developer I build custom Web Application products for B2B clients, from interface to backend. Most of my work is Full Stack Developer React Node delivery, where a React frontend and a Node.js backend support one business workflow end to end. As a Node.js Developer I own the REST API logic, authentication, roles and permissions, and the data layer behind each product. My focus is practical Web Application Development that ships, scales, and stays maintainable, with clean API Integration at the core. Across 14+ years and 130+ completed projects I have built 60+ SaaS, CRM and dashboard products, 40+ admin panels and client portals, and 200+ REST API integrations. As a React Developer and Full Stack Developer with experience leading development teams of up to 6, I have shipped for 50+ EU and US B2B clients across SaaS platforms, CRM systems, marketplaces, booking websites and API Integration projects. As a React Developer I build Web Application interfaces with React.js, Next.js, TypeScript and Responsive UI , wired to live data through API Integration . As a React Frontend Developer and Frontend Developer I deliver usable, fast interfaces — data tables, filters, admin panels and client portals. On the backend side, as a Node.js Developer and Backend Developer I build the REST API layer, ExpressJS services, authentication, roles and permissions, payment flows and CRM integrations. Many clients come to me as a Node.js Developer when a frontend already exists but the API, the data model and the business logic need to be done right. As a Backend Developer I keep the Node.js layer predictable and documented, and as a Node.js Developer I handle the API Integration between third-party services, the database and the frontend. A typical Full Stack Developer React Node project for me looks like this: a SaaS platform or internal business tool with a React frontend, a Node.js backend, a structured database and an admin workflow for the team behind it. On every Full Stack Developer React Node build I design the database structure, the REST API , the dashboards and the permissions model so the product holds up as it grows. This Full Stack Developer React Node approach keeps frontend and backend in one system. Hiring one Full Stack Developer React Node engineer also keeps the React Developer and Node.js Developer decisions consistent across the whole build. I also work as a Directus Developer and Headless CMS Developer . On 20+ content-driven and data-heavy products I use Directus CMS or Strapi as a headless backend, which gives clients a clean admin panel and an API-ready foundation. As a Directus Developer I model the data, set roles and permissions, and connect a React frontend through REST API ; as a Strapi Developer I do the same on Strapi. Headless CMS work with Directus CMS pairs naturally with my React Developer and Node.js Developer delivery. Stack I use daily: React, React.js, Next.js, Node.js, TypeScript and JavaScript on the application side; ExpressJS, REST API and API Integration on the service side; SQL, MySQL, MongoDB, Firebase and Supabase for data; Directus CMS and Strapi for headless content. Authentication, roles and permissions, payment flows, dashboards, data tables, filters and admin workflows are standard parts of how I deliver Web Application Development . How I work on a Full Stack Developer React Node project: discovery and scope first, then architecture and backlog, design where needed, development in sprints, QA on staging, production release, and support after launch. As a Web Developer with 14+ years behind me, my main promise is delivery predictability — clear scope and no surprises. As a JavaScript Developer I write code the next developer can actually read and extend. Typical projects clients hire me for: SaaS platform development, CRM systems, admin panels, marketplaces, booking websites, lead generation websites, dashboards, client portals, internal business tools, e-commerce platforms and API-based Web Application work with workflow automation and business automation. Clients also find me under related searches that match my real stack. On the React side: React Native Developer , React Native App Developer , React Next.js Developer , React Developer Firebase , and Full Stack Developer Supabase React . On the full stack side: Python Full Stack Developer , Full Stack Developer AI , Full Stack Developer Shopify , Full Stack React , Full Stack Node.js React and Node.js React . On the backend: Node.js Backend Developer and Back End Developer Node.js . I also fit Front-End Developer Full-Stack , Python Developer , WordPress Developer , Mobile App Developer and Senior Full Stack Developer . If you need a React Developer , a Full Stack Developer React Node engineer, or a Node.js Developer for a serious product, I can take it from architecture through release and support. Let's talk about your product and what it needs to do.
