I go for long walks at night a few times a week and find myself journaling a lot then. It got annoying to stop my walk to type out a thought so much, eventually I started primarily voice typing instead.
But I still had to stop and pull up the Google form, then start voice typing, fix any mistakes, and then continue the walk. So I moved on to just turning on a recording app on during the walks and just start talking whenever I want without having to stop or pull out my phone.

I transcribe the audio file when I get home and add it with a summary to the journal.
Now I keep a livestream going while I'm working at my PC and transcribe and summarize whatever happens there too.
It’s designed for exactly this kind of use—hands-free, continuous voice capture while you go about your day. You get access to your raw data through an open API, so there’s no lock-in.

i have seen some try and fail in an effort to save $perceived_value
Dedicated Real-Time Cores: Many SoCs include dedicated cores specifically for hard real-time tasks.
Microcontroller Companions: Pairing a microcontroller running a lightweight RTOS with a larger, general-purpose processor as a supervisor (You can use normal Linux).
FPGAs: Custom FPGA implementations can deliver deterministic timing where ultra-low latency or specialized processing is needed.
I've retrofitted some near unmaintainable embedded systems, and one of the easiest ways to improve spaghetti code is refactoring some of the vars into state machines/statecharts.
Btw, state machines play well with event sourcing and clustering.
EG: Subdivide a flat projection of earth into n^2 squares. Create an array of length n^2. Set the value of each element in the array to a list of canidate geofences(which have area in that square).
Scale lat and long between 0 and 1. Then you can index directly into it with PrecomputedArray[floor(lat*n+long)]
This is trading space for time, may as well choose space here.
Great approach!
Remote: Yes (US time zones preferred)

I am a Software/Firmware Engineer with 14+ years of experience bridging the gap between hardware constraints and user experience. I specialize in system optimization, embedded systems (bare-metal to Linux), and scalable backends.
Highlights:
- Firmware: Yocto, Zephyr, Linux, FreeRTOS, BLE, DSP, ARM/MIPS/x86.
- Backend/Infra: AWS (CloudFormation, IoT), Elixir/Phoenix, CI/CD pipelines.
- Recent impact: Owned the full audio pipeline at Limitless AI (from firmware audio codec to backend storage) and optimized audio playback latency to <800 ms at p99. At R-Zero, reduced the firmware flashing step by 10 minutes per unit on the manufacturing line.
- Experience: Limitless AI (Wearable), SunPower (Energy), and R-Zero (IoT Health).
Comfortable owning the stack end-to-end—from low-level drivers and real-time firmware to backend ingestion, cloud services, and operations. Strong recommendations available from leads at my last 3 projects.
Open to consulting or full-time. Happy to hop on a call to review your architecture or discuss optimization bottlenecks.
