Canonical site: https://aseemsavio.com/ Last updated: 2026-11-02 ## Short biography Aseem Savio is a software engineer who likes the unglamorous work: making large systems feel small, fast, and boringly reliable. He designs and builds data-intensive distributed systems and owns the whole arc - architecture, collaborating with the engineers who build them, and getting them delivered. Most days are spent with events, queues, storage, and the engineers who argue about them. He has been shipping software since 2018. He is a maintainer of PyTenable, Tenable's official Python SDK for its REST and GraphQL APIs, which is used by more than 85,000 people each month. He writes about software architecture, distributed systems, data modeling, and technology at blog.aseemsavio.com, and shares his photography at photography.aseemsavio.com. Outside work he is a coffee enthusiast, baker, pianist, wildlife photographer, Formula 1 fan, and PS5 gamer. He self-hosts services on a home Kubernetes cluster and is a Catholic Christian who reads theology. ## Entity facts - Full name: Aseem Savio - Also written as: Aseem, aseemsavio - Job title: Senior Software Engineer - Specialism: Data-intensive distributed systems - Experience: 8+ years (career start: 22 August 2018) - Public repositories: 52 - Best-known project: PyTenable (85,000+ users per month) - Website: https://aseemsavio.com/ - GitHub: https://github.com/aseemsavio - LinkedIn: https://in.linkedin.com/in/aseemsavio - Instagram: https://www.instagram.com/aseem.savio/ - YouTube: https://www.youtube.com/@aseemsavio6696 - Blog: https://blog.aseemsavio.com - Photography: https://photography.aseemsavio.com - Contact: https://aseemsavio.com/#contact ## What he works on Aseem Savio designs the architecture for event-driven distributed systems that operate at petabyte scale of customer data. His work focuses on the parts that keep people up at night: throughput, backpressure, consistency, durable storage, systems operating within SLAs, and the 3 a.m. page that should never arrive. He builds these systems for failure, with isolation for failed work and telemetry after shipping. He also leads delivery: scoping the work, collaborating with fellow engineers, unblocking, and staying until it ships. ## Open-source projects ### PyTenable - maintainer The official Python SDK for Tenable's REST and GraphQL APIs.
