DesignFirst develops IoT Edge products and specializes in embedded security. We have a track record of delivering new products, including medical devices, industrial systems and new wearables.

TPM.dev offers developer-friendly security. TPM.dev is accelerating the adoption of Trusted Platform Modules (TPM 2.0) and other hardware security (HSM) for better system and software protection. We hold an annual developers conference. Our 5th annual conference is in Cambridge (UK) and our gold sponsor is Infineon Technologies AG.

I was responsible for the creation of two training courses about hardware security for software developers. Introducing newcomers and beginners to the world of Trusted Platform Modules (TPM) with TC1101 course, and transferring know-how of more complex security functions in the TC1102 Intermediate TPM usage course. TC1101 was released to the public in March of 2024 and TC1102 is released in October 2024.

Edge Impulse is the leading Edge AI platform for building and deploying ML to edge computing workloads, from low power devices to rich embedded systems. I helped integrate the EdgeImpulse SDK with new silicon products (MCU, SoC and ASIC). I created a self-serve variant of the EdgeImpulse integration for embedded systems to streamline cost for the company and increase efficiency of the Embedded Engineering Team. I also contributed to business processes, including Open-Source licensing.

EnactTrust improves the security of IoT systems and attracted the interest of Porsche and Bank of America.

Over 2 Billion applications and devices are secured with wolfSSL products, including smart grid, IoT, industrial automation, connected home, M2M, automotive, aviation, and more. I led the design and development of a new embedded software stack for Trusted Platform Modules (TPM/HSM) - wolfTPM. I was involved with customer-facing engineering for various projects, medical, aerospace, IoT, etc. Additionally, I helped the company with many blog publications and content for webinars.

Bulgaria took a great leap forward and Investin.bg is my way to share the modern story of foreign investors and local entrepreneurs in Bulgaria.

Graz Area, Austria

Joined the SW RnD Team at LogicData for a Project related to Low-level Embedded Systems Design and Programming. Main outcome:* Design and implementation from Scratch of a Bootloader for Cortex-M based SoC with 802.15 Radio. Main characteristics:- Hardware Platform Agnostic - My proposal for Bootloader which to be Hardware Agnostic was encouraged and supported by the Client. This allowed me to create truly re-usable implementation, e.g. with and without Nordic SoftDevice, ARM CortexM or any other non-ARM MCU.- Applied Design First approach with Design Specification from the start, in nutshell Engineering process by the book. And Client approved of every extra effort proposed to achieve this higher Quality.- Transport Layer Agnostic - Can work with Bootloader Protocol Data over Radio or Serial Wired Interface, or any other Transport.* Due to the specific System Architecture with main and secondary MCU, I also developed an additional functionality in the primary MCU to allow communication from Host to Radio SoC.- Integrated in existing Protocols and Communication Layers of Main MCU- Initially created only for the means of Bootloader and FW Update.- Later on I extended the so called "Tunnelling" functionality to support multiple "Bridge Modes" and implemented in total four(4) different Modes. - Two of which Bridge Modes were created to allow more detailed Production Testing of the Radio SoC Firmware and functionality.* Took part in "RF Task Force", which main objective was to solve Technical Challenges in the Radio Communication of the Complete System. Several significant contributions, most notable:- Detailed Research and Documentation effort for RF Parameterization- Extensive Testing and Benchmarking of the RF Performance of the System.* Took great interest in the Company Environment and was active in the SW RnD Team Meetings and Discussions. Note: LogicData has an amazing Environment for Collaboration, I can only highly recommend them as Client.
