    Software developer and occasional devops guy with decades of experience working up and down the Linux software stack -- I've done everything from systems administration and devops to application programming and kernel hacking. I have been involved with cryptocurrency since 2013 and have an understanding of the underlying technologies, market fundamentals, and macro/micro market cycles within the space. Accomplishments include: * Doubling the performance of Oracle's BlueKai ad serving platform, saving millions of dollars in yearly data center costs. * Designing AnchorFree's OpenVPN and Apache-based VPN and ad- delivery platform used to serve millions of ads per day. * Designing a virtual file system layer and associated Apache module that increased site I/O throughput by 400% and obviated the client's poorly-performant proprietary storage system.

    🚀 I’m Paul, from Tauranga, New Zealand. I can help you build interesting things! Over the last decade I’ve worked with organizations ranging from early-stage startups like SafariDesk, ButlerPad or CleverCare to medium-sized businesses like Blueprint Data, Tangent, or Westpac Bank all the way up to giants like Google, NASA, InfoSys and the Chinese aerospace industry leader COMAC. "[Pauls solution] ClusterGL is an innovative solution...this technique shows the most promise" - NASA / JSC As a software developer and project architect, I’ve helped build everything from high-performance big-data systems to complex web applications to 3D rendering engines, working alone or as part of a team. And if you play independent games on Android, you’re likely using code I’ve worked on. "[Paul is] a talented and experienced programmer..." - Mbwana Alliy, Managing Partner at Savannah Fund I've also had the dubious honour of being on the front page of HackerNews and Reddit at once :)

    I am an experienced Embedded Design and Firmware Developer with over 8 years of hands-on experience in developing cutting-edge solutions for various microcontrollers and microprocessors. With a deep understanding of industry-standard peripherals, I have a proven track record of delivering innovative and robust products. Here are some of my notable projects that showcase my skills and experience: 5G RU Radio design: As a key member of a project team, I played a significant role in the design, development, and production of a 5G RU radio unit for one of my clients. My responsibilities included participating in system design, defining the architecture, optimizing the bill of materials, developing firmware, and creating a manufacturing test suite. To accomplish these tasks, I utilized advanced chipset such as Xilinx MPSoC and RFSoC, Intel Agilex, Stratrix, and Cyclone 10 across various product variants. Home Monitoring Device: I designed and developed the firmware and cross-platform GUI application for a home monitoring system using the CC3200 WiFi chipset. To ensure optimal performance, I utilized both TI RTOS and Micrium uC/OS RTOS. Fitness Wristband: I was a key contributor in the development of a fitness wristband that monitored step count and sleep cycle. This project utilized the CC2541 BLE chipset to run the fitness algorithms and handle data communication. AI-Based Heart Diagnosis Device: I designed and developed an AI-powered heart diagnosis device that was battery-operated and used heart sound for US clients. The device used the CC5545 DSP for audio sampling and enhancement, an OSD3358 chip for AI edge computing, and a panasys circular display to show the results. I also performed the bring-up of the OSD3358 in the latest Yocto and Kernel 5.8 support. Timestamp Logging Device: I developed a BLE-based timestamp logging device that used the CC2541 to monitor time and send data to nearby mobile devices. Mesh based sensor data collection: I developed a BLE mesh-based sensor data collection form where multiple ESP32-C3 devices collects sensor readings and broadcast in the mesh. Then eventually a central node will send the data to a server. In addition to these projects, I have also worked on several other microcontrollers and processors, including Phytec AM572x SoM, OMAPL138, Keystone K2E, AST2600, and nRF52, to name a few. I have also worked with several peripherals such as I2C, SPI, MCASP, I2S, USB, UART, uPP, EMAC, MDIO, NAND flash interface, EMIF, SDIO, and eMMC. In conclusion, I am a highly skilled Embedded Design and Firmware Developer with a wealth of experience in developing solutions for various microcontrollers and microprocessors. With a deep understanding of industry-standard peripherals and a passion for innovation, I am confident in my ability to deliver high-quality solutions for any project.
