Yaroslav Y.

Electronics & Embedded Engineer (PCB + firmware) with strong RF and Power Electronics experience. I help startups and product teams turn an idea into a working prototype - and then into a production-ready design with clear scope, milestones, and predictable execution. ✅ What I deliver end-to-end • Requirements clarification/feasibility, system architecture, component selection, BOM planning • Schematics + low-noise, multi-layer PCB design (Altium / KiCad), bring-up, debugging • Embedded firmware (C/C++), low-power optimization, stability, OTA/update strategy • Prototype build support, validation, DFM/DFT, manufacturing handoff (Gerbers, BOM, assembly docs) ⚙️ Relevant domains • RF & connectivity: BLE / Wi-Fi / LTE / GNSS / Sub-GHz, matching networks, integration constraints • Mesh systems: BLE Mesh / Thread / Zigbee-type networks (roles, provisioning, reliability) • Automotive: CAN / LIN integration, power/EMC constraints, rugged design approach • Power electronics: AC/DC, DC/DC, battery systems, charging, protection, power path, thermal/efficiency considerations • MedTech / wearables: sensor integration and comfort-driven form factor constraints • AI-driven devices: sensor fusion + on-device inference (TinyML/edge-style) where it fits How I work: clear scope + milestones, weekly updates, and practical engineering decisions focused on reliability and manufacturability. NDA-friendly. No purchases without written approval. You receive full sources + manufacturing files. ❗Invite me to your job or message me with your idea - I’ll respond within 24 hours with the right questions and a clear next step.
