One rule: it ships or it doesn't count. ⚡ We've burned midnight oil debugging STM32 register maps, hand-routed RF traces in Altium at 2am, and argued over LangGraph agent memory architectures until someone proved it wrong on a whiteboard. 👇 That's the team you're hiring. ---------------------------------------------------------------------------------------------------------------- ⚙️ The chip guys. STM32, ESP32, ARM Cortex-M. FreeRTOS. Bare metal when it matters. UART, SPI, I2C, DMA — not from tutorials, from production bugs that cost real money to fix. 🔌 The board guys. Altium. Proper ground planes. Impedance-matched traces. Buck, Boost, Flyback. Motor drivers that don't smoke on day two. Gerbers that JLCPCB actually approves first try. 🤖 The robot guys. Quadrupeds. Industrial arms. Sensor fusion. ROS2. Real-time motion control that doesn't twitch. SCADA. PLC. Commissioning on-site when it matters. 🧠 The AI guys. LLMs in production. Agentic pipelines. LangGraph, CrewAI, RAG, AWS Bedrock. Edge inference on Jetson. Models that earn their compute cost. 🌐 The wireless guys. BLE, LoRa, ZigBee, 4G LTE, WiFi Mesh, CAN Bus, MQTT. Connectivity that holds in the field — not just the lab. ---------------------------------------------------------------------------------------------------------------- 🌍 US. UK. Middle East. Australia. Singapore. 🏭 Healthcare. Finance. Robotics. Agri-tech. Industrial automation. We've seen your problem before. Probably twice. ---------------------------------------------------------------------------------------------------------------- ✅ Full-stack — silicon to cloud, PCB to AI pipeline ✅ One point of contact — no handoff chaos ✅ Production-grade — not demos, not prototypes ✅ Fast iterations — we move when you need to move ✅ Long-term partners — not hired guns ---------------------------------------------------------------------------------------------------------------- Volodymyr — and the six engineers who make the deadline real. weniger
