Work
Data platforms first, then AI engineering and research. Each case study names the constraint, the decision and the evidence.
Data architecture and platforms
- 2026wb-cdc-analytics: PostgreSQL to ClickHouse CDC in one command

Research
- 2026 to nowHow small, how quantized? Tokenizer, size and quantization for Amharic SLMs
An independent study of how tokenizer choice, model size and quantization each affect Amharic small language models on a single consumer GPU, with QLoRA recovery tested; submitted to a 2026 workshop, in review.
