Founder Hardware Partner | Prototype, Firmware & Small-Batch Builds

🚀 Turn your product idea into a clear, buildable prototype direction — before you spend time and money on the wrong approach. Many early-stage hardware products fail not because of bad ideas, but because key engineering decisions are made too late or based on incorrect assumptions. I help founders and product teams define the right path early:what to build, how to build it, what to test first, and what to avoid. 🧭 Start here (recommended) If your idea is still evolving or unclear, I recommend starting with a focused feasibility and validation phase. In this phase, we will: • clarify your product concept, constraints, and target use• identify key mechanical, electronic, and manufacturing risks• define a practical prototype direction• determine what needs to be validated before major investment This helps avoid unnecessary iterations and costly mistakes before moving into detailed design, tooling, or production. 🔧 What I do I support early-stage product development from idea to validated prototype: • concept clarification and constraint definition• mechanical architecture and functional-system direction• enclosures, small mechanical systems, and functional assemblies• feasibility and prototype-stage manufacturability evaluation• CAD development in Fusion 360• prototype strategy and iteration planning• supplier communication and manufacturing-feedback coordination• engineering decision support before major investment Rather than only delivering CAD, I help you understand the full path: idea → prototype → validation → next step ⚡ Accelerated exploration I use AI-assisted workflows and 3D tools to improve concept exploration, design communication, and workflow efficiency. AI is used mainly for repetitive supporting tasks. Professional engineering decisions are checked in CAD and validated through physical prototypes, supplier feedback, and real manufacturing constraints. 🏭 From digital to physical I operate a small 3D-printing farm, allowing fast development and testing of physical prototypes. I can support: • functional FDM prototype development• enclosure and mechanical validation• PCB fit and assembly checks• small-batch prototype builds• real-world testing and iteration• prototype refinement before supplier quoting or higher-volume production When appropriate, I combine proven off-the-shelf components with new design work to reduce development time, technical risk, and production cost. 📡 Connected-product prototypes I can also support proof-of-concept connected hardware development, including: • ESP32-based Bluetooth and Wi-Fi functionality• integration of different sensors• basic iOS companion-app prototypes• rapid testing of hardware and software interaction This is useful for validating a smart-product idea before investing in custom electronics, certification, cloud services, or a full engineering team. 🎯 What you actually get • a clear and practical product direction• early identification of risks and constraints• a structured path from idea to functional prototype• CAD and prototype files within the agreed scope• confidence in your next technical and manufacturing steps Not just design — but clarity on what should, and should not, be built. 🧠 Typical projects • consumer products and smart devices• connected-product proof-of-concepts• ESP32, sensor, Bluetooth, and Wi-Fi prototypes• enclosures and functional mechanical systems• hardware startup prototypes• proof-of-concept builds• early-stage product validation• small-batch 3D-printed products 📦 How I typically work Most projects begin with a focused validation phase before moving into full design. This ensures: • the right direction is defined early• risks are identified upfront• time and budget are used efficiently• prototype testing informs the next design stage For suitable projects, I can support the full early-stage development path: concept clarification, mechanical and connected-prototype design, functional testing, 3D-printed iterations, and small-batch prototype builds. Projects can begin with a paid feasibility phase and then move forward through clear fixed-price milestones, depending on the scope and validation results. 📩 Next step If you are exploring a new product idea and want to move forward with more clarity and fewer mistakes, please share: • your product idea and target user• sketches, reference images, or an existing prototype• what you need to validate first• target quantity and intended manufacturing process, if known• approximate budget and timeline I will help you identify the most practical next step.
