The engineering and architectural firm I'm affiliated with is registered in CA, OH, TX, MI, MN, and FL (if you need a stamp from other states it's advisable to ask the county/Authority Having Jurisdiction if they will accept the stamps from the aforementioned states. We can also do the surveys, on-site dimensioning, etc (in-person if needed). The minimal price for stamped work (including the review) is 2,000.00 USD. Stampless work is more affordable.

ATEH.tech is a engineering team specializing in Embedded Systems, AI Vision, custom electronics, and Linux-based devices. We specialize in projects that require expertise across electronics, embedded Linux, cameras, and system integration. We help founders, startups, and engineering teams turn ideas into working products — from architecture and hardware design to embedded software, prototyping, and manufacturing support. Over the last 20 years, we have developed custom electronics, embedded systems, carrier boards, AI cameras, and industrial devices for a wide range of industries including computer vision, industrial automation, telecommunications, security, and IoT. Our expertise includes: • Embedded Systems Development • NVIDIA Jetson (Orin NX, AGX Orin, Orin Nano, Xavier NX, AGX Xavier) • Rockchip Platforms (RV1126, RV1109 and others) • Custom Carrier Boards • AI Vision Systems • Sony Image Sensor Integration • Embedded Linux & BSP Development • Device Drivers & Camera Drivers • High-Speed PCB Design • FPGA-Based Solutions • Prototype Development • Manufacturing Support We typically work with founders, CTOs, and engineering teams who need an exexperienced partner capable of handling both hardware and embedded software development. Whether you are building an AI camera, industrial controller, smart sensor, edge AI device, or a completely new embedded product, we can help you reduce technical risks and accelerate develpment. 💡 AI Vision Focus (Core Strength) We specialize in building AI-driven devices: • Smart cameras and embedded vision systems • Custom carrier boards for NVIDIA Jetson (Orin / Xavier) • Image sensor integration (Sony IMX series, ISP pipelines) • High-speed embedded systems (MIPI, PCIe, DDR, Ethernet) • IoT, RF and Wireless devices (Wi-Fi, Bluetooth, LTE, LoRA) This allows me to solve complex problems where hardware, software, and AI intersect. 💡 What We Actually Solve A big part of our work is preventing expensive problems before they happen: • Unstable designs caused by poor power integrity • EMI/EMC failures during certification • High-speed signal issues (MIPI, DDR, PCIe) • Thermal and power bottlenecks • Prototypes that fail when scaling to production Fixing these later is expensive — I design systems correctly from the start. 🔧 What We Deliver (End-to-End) • System architecture and feasibility analysis • Schematic design and high-speed PCB layout (HDI, multi-layer) • Embedded software (MCU firmware, Linux BSP, drivers) • AI & vision hardware development (Jetson, ISP, sensors) • Hardware debugging and root-cause analysis • Prototype bring-up, validation, and optimization • DFM / DFT and manufacturing handoff (BOM, Gerbers, assembly docs) • Certification support (EMC, CE/FCC pre-compliance) ⚙️ Core Expertise • AI Vision Systems (smart cameras, edge AI, video pipelines) • Custom Carrier Boards (Jetson Orin, Xavier, Rockchip, NXP) • High-Speed Design (DDR, PCIe, MIPI CSI/DSI, USB 3.x, Ethernet) • RF & Wireless (Wi-Fi, BLE, LTE, GNSS) • Power Electronics (DC/DC, battery systems, PoE) • FPGA & SoC-based systems 🧪 Prototyping & Lab We maintain a fully equipped engineering lab: • Oscilloscopes, logic analyzers, spectrum analysis • PCB prototyping, soldering, rework • CNC and 3D printing • In-house bring-up and validation This allows me to identify and fix issues early — before they reach production. 🧩 How We Work • Clear requirements and system-level thinking • Structured development with milestones • Regular updates and transparent communication • Focus on reliability, manufacturability, and cost efficiency No guesswork. No disappearing after the prototype. 📦 What You Get • Production-ready hardware — not just a prototype • Stable, predictable system behavior • Reduced risk of redesign and manufacturing issues • Faster time-to-market • Complete documentation for scaling production 🏁 Let’s Build Something Serious If you're building a complex AI device, smart camera, or embedded system — or fixing hardware that doesn’t behave in production — We can help. Send me a message with your idea or current challenges — I’ll respond with the right questions and a clear next step.

Feedback: 💭 "Roman has a vast knowledge of what he is doing and really good at what should be done" 💭 "He has good social skills; is patient and a good communicator. His skills are very much in demand" 💭 "If some solution does not work or is not possible Roman will find another way to get the task done" 💭 "His research is solid, resulting in a good overview of possibilities to (re-)direct the project" Introduction: I'm a software engineer with 20 years of experience and more than a decade in architect and tech lead roles. My strength lies in combining deep technical expertise with a big-picture understanding of how modern software systems evolve over time. I help businesses build reliable, scalable, and maintainable systems -- whether by designing new solutions from the ground up or by rethinking and refactoring existing systems into clean, resilient architectures. Over the years, I have seen how software can become either a long-term business liability or a strong foundation for growth, and my goal is always to help clients achieve the latter. My experience is backed by a strong track record of completed projects, enterprise-level engineering work, and positive customer feedback. After building a successful career in enterprise software, I now work as a freelancer with clients around the world, helping them solve complex technical challenges with clarity, reliability, and long-term thinking.
