Hire the Best Internet of Things Specialists
in Indonesia

20 years of experience in multiple multinational companies as a consultant, engineer, and developer. Worked in many environments such as telco companies (Siemens, Nokia Siemens Network, Huawei, Telco Operators), metering companies (Actaris/ITRON, EDMI, Blue Star, Qingdao Techen), mobile money, IoTs, one of the biggest startups in Indonesia and worked in projects across the world. Live with Linux since the year of 2000 (Debian 2.x - potato) till now. Worked on IT/IP network, low-level protocols, metering, scraping, and analytics. Proficient in Golang and some other languages such as Python, Zig, C, C++, and Javascript.. Familiar with Linux embedded systems (build root, raspberry pi, arm SBC). I've done many Lorawan implementations for many applications such as metering, & tracking.   I have worked on AMR/AMI (Automated Meter Reading/Advanced Meter Infrastructure) systems, working from CSD to IP based/4G era until IoT (rf-mesh, PLC, LoRa/Lorawan), and also hacking protocols of various electricity meters or other systems. I’m very familiar with low-level DLMS protocol, FLAG, and proprietary meter protocols such as EDMI Atlas/Genius meter.  I also work on other IoT devices (non-metering) such as RFID/LLRP, RTLS/UWB, BLE, and Lorawan for tracking. Other works mainly in data analytics and performance/optimization. One of the optimization samples, where I optimize the reading/processing ~4GB document in less than 0.5s (yes, less than 500ms) can be seen in my GitHub: rissw/not_yet_hit_the_wall. Or how I process ~42GB single structure JSON data of an insurance data and join the data within in less than 3 minutes. (While the original Python script from the client can complete the task in some hours) in my work samples. So, what can I do for you? - IoT consultation - IoT Development - Lorawan-related job (Chirpstak v3/v4, TTN, and its customization, you name it) - Backend development, or any kind of development especially in Golang - Metering protocol or other protocols...I love protocol, i love data in hex and can stare on hex for hours. - Data parsing, especially when you need the process to be fast, correct and use less CPU/memory. - Converting your existing code (Python, Perl, Javascript) which is less performant to Golang or Zig. - Edge computing with single board computer (Raspberry, Orange Pi, etc) - Network-related stuff, VPN (esp Wireguard), BPF, protocol analytics? lets talk...! Another side of me... - I'm not a Frontend engineer, not that I'm unable to do javascript frontend libraries & frameworks, I do know Vue and React, however, it's not my good side of the development to build sophisticated/beautiful frontend. However, I do know how it works and how to modify/enhance the frontend functionality. - I'm not a DevOps engineer, however, I've worked on some projects running on Digital Ocean, AWS, Azure, Fly.io, and Oracle Cloud. I'm good with docker and quite familiar with helm chart, and Argo CD. - I'm a fast learner and open to new challenges, hit me with your requirements, I might have already done a similar project or touched the subject to some extent. I might be able to do a quick catch-up on your subject/requirement. - If you need more than 1 day of discussing what you want to do, or are still not sure what you want to do, I don't have much time to do so, but you can always hire me for consultation. Still not sure? Drop a chat during my workday (09.00 - 17.00 GMT+7), I'll be quick to respond.
