đ§âđ» About toString()
Hey, Iâm Marco Altea, a software engineer and Senior Architect whoâs spent the last 10+ years shipping software, from early-stage for Fortune-500 stacks.
I created toString() because I want to have a way to keep track of learning and interest in engineering and share it with other engineers.
What youâll find here
Deep dives on practical engineeringâretrieval-augmented generation, scalable data pipelines, model-ops, and the architectural trade-offs, review of new platform etc.
Post-mortems & war storiesâthe bugs that cost us days, the fixes that took minutes (after we finally found them)
Reading & tool recsâthe books, papers, and open-source libraries that actually changed the way I build software.
No hype, no paywalls (for now), just honest notes from the trenches.
