Smart Luggage Firmware Developer Needed

@hayteekeys

Hi, I can join you as a hands‑on firmware engineer in Delhi/NCR to push your nRF52840‑based smart‑luggage product toward production, with a strong focus on BLE reliability and ultra‑low power operation. APPROACH - BLE First: Refine and stabilize the BLE stack (connections, services, throughput, robustness) on nRF52840—this will be my top priority for the first milestone. - Low‑Power Architecture: Design event‑driven state machines coordinating BLE, GSM, and GPS, ensuring aggressive sleep cycles and minimal current draw. - Secure Data Path: Implement and verify end‑to‑end encryption over BLE and cellular using standard crypto libraries supported by Nordic SDKs. - Debug & Stabilize: Production‑grade debugging (RTOS or bare‑metal), stress testing, watchdogs, and deadlock prevention to meet field reliability targets. FIRST MILESTONE - Integrate the revised BLE communication layer into your existing firmware base and validate it on the latest hardware prototype. ACCEPTANCE GUARANTEES - Zero compile‑time warnings - No deadlocks under stress tests - Power consumption within spec across all modes - Encrypted packets verified end‑to‑end PROJECT EXPERIENCE - Deep experience with Nordic nRF52, BLE stacks, and low‑power firmware - Comfortable collaborating closely with hardware, mobile, and cloud teams Happy to discuss timelines and jump in as soon as you’re ready.

Having worked on a diverse range of automation projects throughout my career, I have honed my skills in C programming, electronics, and embedded systems — all of which make me an ideal fit for your smart-luggage firmware development project. I've extensively used SIEMENS TIA Portal, Simatic Manager, Honeywell DCS C200, AB PLC RS Logix 5000 and FactoryTalk, among others. My experience focus has been on building systems that are reliable, efficient and highly functional to match the needs of specific scenarios. Given the Nordic nRF52840 framework you're using,\ I'm not only familiar with this technology stack, but I'm also comfortable working within its low-power constraints. One crucial aspect you mentioned is a rock-solid BLE stack; this is where I can provide tremendous value. My deep understanding and experience in driving event-based workflows efficiently while maintaining encryption across multiple communication links will ensure your product remains secure. In addition, I am no stranger to hard deadlines and working collaboratively with cross-functional teams, as indicated by my history in process automation. You need someone who knows how to push the limits of a system without compromising stability or security - that's me! So if you're searching for a dedicated professional who can bring valuable expertise to your team from day one while meeting demanding acceptance criteria at each milestone, let's talk!
