Senior IoT Engineer building complete IoT systems: the firmware on the device, the cloud that receives its data, and the tools to run a fleet of them in production. RECENT WORK For several years I've owned the platform behind a fleet of EV energy-management controllers - ARM Linux devices that measure a site's electrical load and allocate current between chargers in real time. Real-time sampling runs as bare-metal firmware on the SoC's real-time core and feeds a multi-threaded C++ application through shared memory. Around it: U-Boot boot flow, device-tree overlays, GPIO/I2C/SPI peripherals, Modbus and OCPP to third-party equipment. An A/B update system that cannot brick a device: two system slots plus a persistent data partition, signed bundles, a bootloader-side attempt counter that falls back before Linux starts, and a health check that confirms a new image or rolls it back by itself. Proven on hardware, including power cuts mid-update. A fleet-wide Debian migration done remotely: repartitioning live devices in place, carrying each unit's identity (certificates, VPN keys, calibration) across, and keeping a working fallback until the new system proved itself. No site visits. Cloud side: MQTT telemetry and commands to AWS IoT, Lambda processing into the fleet database, per-device certificate provisioning, WireGuard access to devices behind customer NAT. WHAT I DO Embedded: C/C++ firmware; embedded Linux (Debian and Yocto - own layers, recipes, images); U-Boot, device tree, kernel configuration, board bring-up; drivers and hardware integration; Modbus, TCP/IP, UART, SPI, I2C; performance work and hard-to-reproduce bugs. Updates: A/B images with automatic rollback; signed bundles and key rotation; staged fleet rollouts; application updates from a private, certificate-protected package repository. AWS: IoT Core and MQTT architecture; Lambda services; cloud databases; device provisioning and certificate management; telemetry and remote monitoring; designs that stay cheap as the fleet grows. Python: backend services and APIs; automation and build tooling; data processing; device-management services. Platforms and remote access: fleet-management web apps and real-time dashboards; remote firmware updates; WireGuard VPN and secure SSH tunnelling; diagnostics for devices with no public address. WHY ME Most IoT problems live between the layers - a device reporting the wrong state, an update that works on the bench and fails in the field, a cloud message nobody can trace back to the firmware that sent it. Instead of coordinating separate firmware, cloud and web developers, you get one engineer who follows a problem from the bootloader to the dashboard and designs the pieces to fit. Let's talk about what you are building and find the shortest path to something production-ready.

I am a Computer Science Engineer with a postgraduate diploma in Network Security and 5+ years of hands-on experience delivering quality assurance across real-world systems including web apps, SaaS platforms, hardware-integrated products, and network-centric environments. I have tested products end-to-end before production releases, identifying functional, usability, data-flow, and edge-case issues early to reduce release risk and improve system stability and user experience. What I have Done & Delivered 1. Tested web and SaaS applications across browsers, admin dashboards, and configuration-heavy interfaces, helping teams catch usability and workflow issues before customer impact 2. Performed manual, exploratory, regression, and UI/UX testing, uncovering edge cases that scripted tests often miss 3. Created clear, reusable test plans and test cases, improving test coverage and repeatability across release cycles 4. Logged high-quality bug reports with clear repro steps, severity, logs, and visuals—reducing back-and-forth with developers Automation, Playwright & Collaboration 1. Built and maintained Playwright (TypeScript) automation for critical user flows and regression scenarios 2. Used GitHub for version control, structured commits, and collaboration with engineering teams 3. Applied judgment on when automation adds value vs. when manual testing is more effective, keeping test suites reliable and meaningful API, Network & Security-Focused Testing 1. Tested REST APIs using Postman, validating status codes, payloads, negative scenarios, and error handling 2. Applied a network-security mindset (TCP/IP, DNS, DHCP, VLANs, ports, traffic flow) to identify misconfigurations and stability risks 3. Performed basic application security testing aligned with OWASP Top 10, focusing on risk rather than noise Hardware, System & Device Validation 1. Tested encoder/decoder platforms, firmware, and device WebUIs in hardware-integrated environments 2. Validated firmware upgrades/downgrades across Alpha, Beta, and production releases 3. Verified system behavior involving authentication, networking, and live data flows How Clients Describe My Work 1. Detail-oriented, investigative, and process-driven 2. Clear communicator with developers, product owners, and stakeholders 3. Reliable, security-conscious, and focused on real-world usage—not just happy paths Tools & Tech 1. Playwright (TypeScript), GitHub, Jira, TestRail, Postman, Wireshark, Python (test logic & validation), Agile/Scrum, CI/CD awareness Engagement Model I am open to freelance and hourly work and typically start with a small trial (~10 hours/week) to ensure a strong fit. Hours can scale based on results and project needs.
