I wanted to understand why more cores do not automatically make a calculation proportionally faster. I parallelized a deterministic numerical integration of π in Python and measured runtime, efficiency, task size and memory use.
I wanted more than a portfolio site that reduces me to a list of roles and technologies. llama23 is my blog: I tell the story of how my path moved from bare metal toward software, systems and operations, and what I keep learning along the way.
A Kanban board as a small playfield: stories and tasks look like collectible cards, while authentication, permissions and abuse controls work behind the scenes.
A classic Go service processes MinIO webhooks. In the second path, image events enter NATS JetStream and KEDA scales the Go worker to zero based on consumer lag.
An indoor positioning system built around an ESP32-Wrover, DW3000 and BNO085. Fusion helped in clear line of sight; with a wall in between, systematic error mattered more than noise.
A team project for two different situations: tracking a bicycle over a long period while conserving power, and sending workout measurements close to real time.
