I help U.S. businesses navigate SMS approval, deliverability, and compliance requirements - reducing the risk of carrier rejections, blocked traffic, and regulatory issues. I specialize in A2P SMS compliance and deliverability, including 10DLC registration, Toll-Free Verification (TFN), and TCPA/CTIA consent audits, as well as diagnosing carrier-level delivery problems. My work focuses on aligning SMS programs with current carrier and regulatory expectations so they can operate and scale responsibly in the U.S. market.

What I Do • 10DLC brand & campaign registration (new submissions, rejections, reclassifications) • Toll-Free Verification (TFN) setup and resubmissions • TCPA / CTIA compliance audits (opt-in flows, disclosures, opt-out handling) • SMS deliverability diagnostics (carrier filtering, content flags, throughput limits) • Platform-specific guidance (Infobip, Twilio, GoHighLevel, ClickSend, SimpleTexting) • Compliance-aware SMS automation (webhooks, triggers, rate-limiting, quiet hours)

ABA (Applied Behavior Analysis) therapy and mental health practices lose thousands of dollars every month — not because of bad providers, but because of denied claims, missed authorizations, and billing errors that go unnoticed.

Specialisms: Connected products end-to-end — firmware, companion apps, security, OTA, long-term support Platforms: iOS, macOS, RTOS, bare-metal Firmware / SDKs: Zephyr RTOS, Nordic nRF Connect SDK, FreeRTOS, Silicon Labs Connectivity: Bluetooth LE, LTE-M / Cellular, Wi-Fi, USB MIDI Languages: C, C++, Swift, Objective-C, Python Types of work: New product development, technical audits & hardening, long-term device support, consulting Currently focused on: secure-by-design firmware, robust OTA architectures, and long-term lifecycle support for devices already in the field I run NRB Tech, a UK-based consultancy that helps hardware teams build, harden, and support connected products. I work directly with founders, CTOs, and product teams as senior engineering — typically replacing or complementing an internal firmware team — across firmware, companion apps, secure OTA, and long-term device support. Engagements are structured around decisions and outcomes rather than open-ended time and materials, and you work directly with senior engineering throughout. Selected work: • AirTurn — sole developer of the iOS App + SDK, Mac App, and Zephyr-based firmware platform powering a decade of Bluetooth pedals and remotes used in music, accessibility, and presentation workflows. • KēZ — complete firmware, iOS app, and backend integration for an LTE-M vehicle security product with OTA updates and live diagnostics, designed to be safe to leave deployed for years. • Positive Grid — modern nRF Connect SDK / Zephyr firmware platform for Bluetooth + USB MIDI guitar controllers, with secure updates and long-term maintainability. • ROUTES — distributed control and monitoring system (Raspberry Pi, Python, MQTT, WireGuard) for a large-scale public art installation operating with remote connectivity and low maintenance overhead. How I typically engage: 1. Connected product development — firmware, connectivity, and system architecture for new products that need to ship and stay maintainable. 2. Product hardening & technical audit — independent review of security, reliability, update strategy, and long-term support risk, with a prioritised report and remediation guidance. Useful before a major release, customer deployment, compliance milestone, supplier handover, or acquisition. 3. Long-term device support — monthly retainer covering security patches, bug fixes, dependency and toolchain updates, and lifecycle ownership for devices already in the field. Most engagements start with a short discovery phase or a fixed-scope audit, producing a written plan covering priorities, risks, and next steps before any larger build. Architectures are designed for OTA updates, long product lifecycles, and field reliability — with security, update strategy, and key handling considered from day one. Based in the UK, working with clients across the UK, Europe, and internationally. If you're building a connected product, inheriting a codebase, preparing for a customer rollout, or carrying a long-term support burden you'd like to hand off — happy to talk scope on a quick call.
