I specialise in challenging go-to-market projects, designing and developing devices, circuits and software where the assumptions are yet to be tested and specifications are early phase. Over 20 years I have delivered deep tech programmes for the MOD, NHS and delivered into clients including Abbott, J&J, PALL, and Fujifilm. My training in sensors, electronic circuit design, biochemistry and embedded AI edge systems will guide rapid progress. My PhD focused on machine learning of receptor structures for biosensing applications, combining electronics design, computational modelling of biological systems, and sensor development. Clients often arrive with an early-phase concept, a market need, and a scope that is unclear. My first job is to identify which assumptions actually matter, design the experiments that test them, and produce a proof of concept with real evidence behind it. For teams past that point, I take that foundation through full hardware development to a compliant, market-ready device with all the certificates of conformity. I build first prototypes in-house using my own prototyping equipment, without the cost or lead times of an external build house. I design and review electronic circuits and schematics, lay out PCBs in Altium Designer and KiCad, develop embedded firmware in C and C++, design and prototype wearables from concept through to enclosure in SolidWorks, and prepare the regulatory evidence required for CE marking, UKCA, and EU MDR submissions.

From concept to tested prototype, I design high-performance PCBs and embedded systems for startups, engineers, and product teams who need results that work the first time. With 8 years of experience in embedded systems and hardware design, I specialize in creating production-ready electronics that are efficient, reliable, and built for scale. Whether you're developing a new product or improving an existing design, I bring the technical expertise and problem-solving mindset to get it done right the first time. 💡 What I Offer: 🔹 Embedded System Development: ARM Cortex, STM32, ESP32 🔹 Advanced PCB Design: From 2-layer to complex multilayer boards with BGA, RF, and high-speed signals 🔹 Cost-Effective Engineering: Focused on value without compromising quality 🔹 Rapid Prototyping: Helping you move from idea to working prototype quickly 🔧 Core Technical Skills: ✔️ Analog & Power Circuit Design: LED drivers, SMPS, sensor interfacing ✔️ Motor Control & Drive Systems ✔️ Signal Integrity & EMC/EMI-Conscious Design ✔️ Communication Protocols: RS232, RS485, I2C, SPI, UART, CAN ✔️ Firmware Development: Embedded C/C++ for real-time applications 🛠️ Tools & Platforms I Work With: 👉 Altium Designer – Industry-standard PCB design 👉 LTspice – Analog simulation & validation 👉 Proteus – Embedded system simulation 👉 Signal integrity tools and EMI/EMC testing preparation 🚀 Why Work With Me? ✨ Proven record of delivering on time and exceeding expectations ✨ Strong communicator who makes complex things simple ✨ Practical experience with certification-ready hardware ✨ Affordable, efficient, and results-oriented 🎯 Let’s Build Something That Works Whether you're launching a new product, troubleshooting a design, or scaling to production, I’m ready to help bring your vision to life with solid engineering and dependable execution. 👉 Check out my work: github.com/zainsiddiqui-zz 📩 Let’s connect and build your next success.

Most organizations already have Microsoft 365. What they often don't have is a well-structured system behind the way work actually gets done. That usually shows up as approvals running through email, processes living in spreadsheets, documents without proper version control, and teams spending time on work that should largely run itself. That's typically where I get involved. I work with organizations to design and build Microsoft 365 solutions that bring proper structure to internal operations - built on SharePoint, Power Apps, Power Automate, and Power BI. I've been doing this for over 10+ years, working with organizations across the UK and Europe - operational teams, regulated environments, enterprise business functions. The work spans SharePoint Online, SharePoint On-Premises, and the Power Platform depending on what the situation calls for. The kind of work I do most: Building Power Apps that replace spreadsheet-based processes with proper business applications. Designing approval workflows in Power Automate with clean routing logic, escalation handling, and audit trails. Setting up SharePoint environments that are structured for the long term - right permissions, right architecture, right governance from the start. Building Power BI dashboards that give operational teams actual visibility into what's happening. Delivering document management systems where documents go through proper lifecycle stages before they're published. Setting up SharePoint intranets and employee portals that connect properly with Teams and Outlook. Connecting Microsoft 365 to external systems through REST APIs and custom integrations. Building AI-powered automation using AI Builder for things like invoice processing and document data extraction. Projects I'm regularly brought in for include document control and approval systems, procurement and purchase order workflows, capital project authorization, employee onboarding and HR self-service, inspection and compliance management, resource and room booking, operational reporting, and multi-level approval systems across Finance, Operations, and Executive functions. I don't typically get involved in single-task work. Most of the time a business process has grown beyond what email and spreadsheets can handle, or an existing system wasn't built properly and needs rethinking. That's the kind of problem I work on. The way I approach it is practical and architecture-led - clean data structures, maintainable logic, clear permissions, and a solution that the business can actually manage and build on going forward. If that sounds like what you're dealing with, I'm happy to take a look at what you have and talk through what a properly built solution would look like.
