Engineering Reliability into the IoT
BIII TECH is a small, founder-led embedded engineering practice. Every project is run by the engineer who writes the firmware — 10 years across BLE, low-power and safety-critical systems, from board bring-up to companion apps on both stores.
That means no account layer between you and the person solving your problem, and no capacity we cannot actually staff. When a project needs more hands than we have, we say so.
Core Engineering Philosophy
Our approach shifts the focus from "making it work" to "making it last." Reliability is engineered, not added as an update.
Design for Manufacture
Ensuring hardware is ready for mass production from day one. We minimise revisions by selecting components with long lifecycles and accessible supply chains.
Security First
Robust security at the firmware level — secure and two-stage bootloaders, signed OTA images, PKI certificate-chain trust and encrypted credential protocols like OSDP. Data integrity is never an afterthought.
Scalable Architecture
Building systems that grow with your data needs. We design modular firmware architectures that separate application logic from hardware drivers — one platform has shipped as several different products off a single shared, code-protected core.

From Prototype to Production
Most projects fail not in the prototype phase, but in the transition to scale. Our workflow is designed to identify bottlenecks early — on one project that meant a harness replaying hundreds of recorded field trips through the real compiled algorithm, cutting months off device testing before anything shipped.
Requirements Analysis
Defining constraints, power budgets, and BOM costs.
Agile Prototyping
Rapid iterations to validate core sensor logic and connectivity.
Production Hardening
Optimization, security locking, and test fixture development.
