Personal details
Sebastian S.
Summary
I bring over a decade of experience in a full-stack development across diverse technologies crucial for SaaS and backend solutions. I comfortably navigate all the communication nuances from business, product, design and engineering back and forth. My expertise lies in collaborating with diverse functional teams and engineering colleagues to design highly reliable solutions, particularly with high-throughput backend engineering as for example in Telna where I've help the their service go from 9Kops to 27Kops. I thrive in distributed teams and diverse multilingual/cultural environments and I'm very open yet currently having a preference to work with great teammates in a blockchain related project with Rust.
+10/y remote work experience in diverse small distributed teams and
+20/y total in software engineering (very strong at OOP)

Work Experience
- Successfully led a team of four in a six-month effort to refactor the main backend code, effectively resolving tech debt issues that were impeding containerization.
- Developed and successfully implemented a Proof of Concept within 2 days to showcase the migration of the persistence framework from Voyage to Mapless.Achievements
- Demonstrated a Rust caching system to extend the main backend capacity, currently above 25Kops and leveraged parts ofthe PoC to continuously expand production capacity beyond 1 Peta Byte in May 2023.
- Added a stress testing layer with a custom Golang multithreaded client to produce synthetic traffic that guarantees SLAs.
- Lead a team of 6 engineers at Sulvo and designed and implemented the next generation ad server in a JavaScript-based custom stack.
- Implemented the pipeline to automatically deploy globally acrosss regions using GCloud. Achievements
- Implemented an automated deployment pipeline using GCloud, enabling global deployment across regions in a backward compatible way.
