Hardware & IoT Product Engineer | Production-Ready PCB, MCU & Embedded Systems I help startups and product teams turn ideas into reliable, manufacturable hardware products — from early concept and prototyping to mass production (1K–10K+ units). With 6+ years of hands-on experience in hardware & embedded system design, I specialize in production-ready PCB design, MCU-based systems, and hardware debugging, ensuring your product is stable, cost-effective, and ready for manufacturing — not just a working prototype. I have worked on complex designs involving high-speed interfaces, mixed-signal circuits, power management, and embedded control systems, helping teams reduce design iterations, avoid costly respins, and accelerate time-to-market. What I Can Help You With ✔ End-to-end IoT & hardware product development ✔ Schematic design & multi-layer PCB layout (production-ready) ✔ Hardware debugging & root-cause analysis ✔ MCU, FPGA & high-speed interface integration ✔ BOM optimization, Gerber generation & DFM support ✔ Support from prototype → EVT/DVT → mass production Technical Expertise Hardware & PCB Design -Schematic capture, PCB layout, stack-up & impedance planning -Power integrity, signal integrity & mixed-signal design -Tools: Altium Designer, KiCAD, OrCAD, EasyEDA Embedded Systems -8-bit / 16-bit / 32-bit ARM microcontrollers -FPGA-based designs and external memory interfaces (SDRAM, DDR2/3/4/5, LPDDR) Analog & Digital Circuits -ADC, DAC, Op-Amps, voltage regulators -Transistors, MOSFETs, power & protection circuits Communication Interfaces -RS-232, RS-485, SPI, I²C, I²S, UART -USB, Ethernet PHY, LVDS, CAN, LIN, PCIe Production & Validation -Hardware bring-up & validation -Lab equipment: oscilloscope, DMM, soldering & rework -Manufacturing support for low to high-volume production Mechanical Integration -Basic 3D CAD support for enclosure & PCB fit validation Why Clients Work With Me ✅ Strong focus on manufacturable & scalable designs ✅ Clear communication with engineering & non-technical teams ✅ Experience bridging R&D and mass production ✅ Practical, real-world hardware — not theory-only designs 📩 If you’re looking for a reliable hardware engineer who can deliver production-ready designs and support your product through manufacturing, feel free to reach out.

I’m an Indianapolis-based Electrical Engineer with a B.S. from Purdue University and over six years of professional experience in electronics design, embedded systems, and precision prototyping. As owner of Proteus Evolution, I offer complete product development and small-to-mid volume manufacturing, combining electrical design, mechanical design, fabrication, and testing under one roof. If you’re looking for a hands-on engineer who can design, assemble, and build your product from concept through fabrication, I can provide a fully integrated workflow that includes PCB design, firmware development, 3D modeling and printing, and CNC machining. I bring practical engineering experience, professional documentation, and in-house production capability to every project. PCB Design, Assembly, and Testing: I design detailed schematics and multi-layer PCB layouts in Altium Designer and Proteus VSM, engineered for signal integrity, manufacturability, and cost efficiency. I also handle surface-mount and through-hole assembly using pick-and-place systems, solder paste stencils, reflow ovens, and precision rework tools. Each board is inspected under magnification and electrically verified for quality and performance. My in-house setup supports production from a single prototype up to approximately 2,500 assembled units, depending on complexity and part density. I can also manage BOM sourcing, part selection, and documentation, ensuring professional results at every stage of the process. 3D Design, Modeling, and Printing: I provide complete 3D design and fabrication services, creating detailed CAD models and producing physical components through FDM and SLA printing. Designs are developed in SOLIDWORKS for accuracy, proper tolerances, and clean integration with electronic assemblies. Each model is reviewed for printability, strength, and fit before fabrication. I work with materials including PLA, PETG, ABS, and engineering-grade resins, producing high-quality prototypes and functional parts. Whether you need a single printed enclosure or a small production batch, I can deliver precise, ready-to-use results that meet mechanical and visual requirements. CNC Machining and Injection Molding: I operate in-house CNC machining and small-format injection molding systems, allowing efficient production of custom parts, housings, and tooling. Integrated Product Development: For clients needing a complete build, I offer an end-to-end workflow that combines PCB design, firmware programming, 3D enclosure design, mechanical fabrication, and system testing. By managing every phase in-house, I ensure tighter tolerances, faster turnaround, and smooth transitions from concept to physical product. Whether you’re developing an IoT device, a functional prototype, or a limited production run, I can deliver fully integrated solutions with professional documentation, tested assemblies, and manufacturing-ready results.
