After 30+ years of my career I think that my role as the System Architect is establishing a bridge between business and development teams, understand business requirements, then design, estimate, plan, explain, prove and take lots of decisions and be responsible for them. With a lot of communication and presentation skills.My major skills, I think, are all in these areas:* Requirements engineering (gathering, analysis, documentation)* System design methods (from structured programming to object/domain/aspect-oriented approaches)* Development process and project life cycle (from waterfall and spiral models to agile, scrum and kanban)* Monolithic and distributed systems* Legacy and refactoring (just love it, honestly)* Performance versus cost analysisI am currently Chief System Architect in a Brazil company Stages (https://getstages.io), which is an online service for video-bloggers and streamers. Stages is designed on top of 40+ AWS services in AWS cloud, with the primary focus on up/down scalability and cost-effectiveness. Aside from the core product, I helped the DevOps team with the architecture and design of the internal CI/CD system on top of AWS CodePipeline and CodeBuild which we called Orion. It turned out to be quite a successful internal project, and I was even invited by AWS to give a short technical presentation about Orion in AWS Days Conference in Prague in 2023.My previous experience (about 11 years) is also related to online video (both on-demand and live-brodcasting), which includes the architecture, design and development of the https://okko.tv (online cinema) and https://okko.sport (online sport).As an architect, during 11+ years with the company, among basic routine tasks of drawing squares and arrows on a whiteboard, I had been experimenting with video transcoders (distributed H.264 and HEVC transcoders, accelerated transcoding with NVidia GPU and CUDA, Elemental Live and Delta). My past experience (1999-2009) is 10+ years in a telecom industry (software for Motorola CDMA and iDEN base stations, J2ME, BREW and Android applications for Motorola phones).In early 1990s, I have even written a book about Forth programming with my classmate. Just imagine, not so many people knew how to program computers at that time. Please look also at my experience log with some more details. Sometimes (twice so far, actually) I write long-read posts in a russian habr.com site:1. HTTP Live Streaming - https://habr.com/ru/articles/178267/2.
