Currently shipping at Reisearch

Engineer who ships products, not slides.

Four years of production work across Go, Python and TypeScript. I build platforms end to end — the pipelines, the APIs, the UIs, and the AWS underneath them.

Who I Am.

MODULE_ID: 0xAB_BIO

Senior engineer. Open-source contributor.

Full-stack engineer with four years of production experience across Go, Python, and TypeScript. Contributor to a stack of major open-source projects: buildkit, atlantis, watermill, listmonk, bbolt, and more. When I find something worth fixing in a tool I build with, I send the patch upstream.

Currently at Reisearch on a small engineering team building a real estate investment platform. My ownership: the comps orchestration system, the AI Renovation Copilot, and the 9.6M-record market data pipeline. Designed those end to end. Co-led an AWS architecture redesign that cut infrastructure costs 40%, and introduced typing and test tooling that dropped production bugs 30%.

I architect systems that scale, mentor engineers on Clean Architecture and AWS, and ship the code rather than write slides about it.

I don't just write code. I ship products that people use.

Software Engineer

Reisearch

Nov 2024 – Present · Remote · Addis Ababa, Ethiopia

Working on a small engineering team building the platform: 34 frontend modules, 16 Go microservices, 23+ DynamoDB tables in production.
Rebuilt a Go-based comps orchestration system into a high-throughput streaming pipeline with DynamoDB and SQS worker pools, cutting processing time from 40 minutes to 4 minutes.
Built a 9.6M-record market data pipeline that ingests raw government TSV files into queryable DynamoDB tables at every geographic level (ZIP, city, county, metro, state, national).
Shipped an AI Renovation Copilot using OpenAI and Gemini that generates photorealistic renovation previews and itemized cost estimates in under 30 seconds.
Co-led an AWS architecture redesign that cut infrastructure costs by 40%. Introduced strict typing, hypothesis-based tests, and pre-commit gates that dropped production bugs by 30%.
Authored architecture and orchestration docs, introduced dependency-injection patterns, and mentored other engineers on Clean Architecture practices.
