My strongest work crosses disciplines into integration: hardware, software, networks, audio, sensors, servers, research and operations. AUDIO & VOICE AAS in Audio Engineering from SAE Chicago, with several years at Mystery Street Recording Studio, including apprenticeship and studio management. My home studio includes a Blue Yeti Pro, MXL 990, Focusrite Scarlett 2i2 and multiple DAWs. I can record two microphone profiles in one take, giving you or your engineer options at the source. I also handle dialogue editing, cleanup, restoration, EQ, dynamics, transcription and troubleshooting. SYSTEMS, IT & CYBERSECURITY 10+ years of hands-on Linux systems administration and technical troubleshooting, plus extensive Windows experience. I work with Linux/Ubuntu, Windows, VPS/server administration, NGINX/Apache, DNS, TCP/IP, VPNs, SSH, SSL/TLS, WordPress, Microsoft 365, Kaseya/Datto RMM, backups, Bash, Python, Git/GitHub, Wireshark, Nmap, Autopsy and Security Onion. I am comfortable restoring broken services, diagnosing unfamiliar systems, integrating APIs/tools and documenting changes. HARDWARE, EMBEDDED & PROTOTYPING I maintain an electronics/RF bench and work with Raspberry Pi, ESP32/Arduino-class hardware, embedded Linux, sensors, SDR, Wi-Fi, BLE, LoRa, cellular, GPS, radar, acoustic/RF sensing, UART/programming interfaces, data logging and COTS integration. I turn technical questions into small, testable experiments and working proofs of concept. RESEARCH, ENGINEERING & OPERATIONS I also handle technical/market research, BOM development, sourcing/cost analysis, lead/business research, technical writing, process automation, feasibility studies, data analysis, website/server recovery and root-cause troubleshooting. My background includes composite manufacturing, prototype/model/tooling work, and roughly a decade owning and operating a Chicago courier business, with practical experience in logistics, scheduling, customer service, vendor coordination and time-critical operations. DELIVERABLES Working prototypes, source code/firmware, server/application configurations, audio masters, BOMs, sourcing research, wiring/architecture documentation, test data, reports, procedures, troubleshooting findings, limitations and next steps. My process is simple: understand the problem, determine what can be tested, build the smallest useful solution, measure what happens, preserve what works and document the result. If I do not already know a platform, language, chipset or tool, that does not automatically make it a bad fit. Systems integration is my strong suit. I am comfortable learning what is necessary to solve the problem. US-based. Remote or willing to travel. Clear communication, practical documentation, and direct reporting of what has been demonstrated versus what still requires testing. less -

It does not prove that it will survive the next hardware revision, pass through EVT cleanly, behave the same across multiple builds, or remain reliable once it leaves the bench. That is where hardware projects become expensive. I work with founders and small product teams to take embedded products from concept or working prototype toward a credible pre-EVT baseline. The objective is not simply to produce a schematic, route a PCB or make firmware compile. It is to remove as much uncertainty as practical before that uncertainty becomes another PCB spin, failed certification attempt, production delay or field problem. My work covers electronic architecture, schematic and PCB design, component selection, firmware, SMD prototype assembly, bring-up and validation. I maintain my own electronics lab, so I can build the resulting hardware, measure its behaviour and challenge assumptions before handing it back. My strongest area is connected and wireless hardware: IoT sensors and gateways, LoRa/LoRaWAN, LTE, BLE and Wi-Fi, together with low-power and battery-operated systems. I work across ESP32, nRF52, STM32 and other platforms, choosing the architecture around the product rather than forcing the product around a familiar development board. Typical work includes: 🔹 Converting development-board prototypes into purpose-built hardware 🔹 Finding power, RF, interface and reliability problems before EVT 🔹 Bringing up and debugging first PCB builds 🔹 Measuring power consumption and wireless performance 🔹 Integrating electronics with enclosures, connectors and wiring 🔹 Separating what has been proven from what is still assumed A board can pass ERC and DRC, boot correctly and still carry expensive problems forward. That is why I rarely treat “it works” as the end of the engineering question. I am probably not the right engineer if you simply need the cheapest route from a schematic to Gerber files. I am a better fit when the next revision needs to reduce uncertainty before more money is committed to tooling, certification, production or deployment. If you already have a prototype, requirements or an early design, show me where it stands and what still needs to be proven. less
