I create software, deliver correct functional and code in time, produce sustainable digital artifacts. I know many techs and use many tools, developed software frameworks and reusable libraries. Experienced in open source, .NET (internals, unmanaged code integration), custom frameworks and API development, Windows, desktop, writing, server side development and enterprise environment (I delete more code than add), technical agility, data. In order to be effective and efficient I tune my thoughts, tools and actions continuously. Computer user since 1993, write programs since 2004, work in companies since 2010, self learner since childhood, do active learning and incremental reading. Applied machine learning is my interest, used against music. Proponent and practitioner of automation, machines should do work instead of humans, like: software generation,testing and deployment; information search and suggestion. IT encyclopedist. Like transparency and science. My titles and roles are - developer, lead software engineer, technical writer, programmer. Sometimes I do - architect, tech lead, team lead, "person who says hard things".
Automatically recognize and highlight covenants clauses within contracts and put these into database. Organized team, found business, bootstrapped solution and guided development.
Used .NET Core, LibreOffice, MongoDb, React.
For meta part of game, bootstrapped actor based solution with websocket frontend from scratch, and automated deployment. For realtime part of game, facilitated migration from bad `OOP` to DOD ECS-like design, reduced copying and GC; coded realtime synchronization and compression; convenient and very fast serialization; improved coding of features using latest(and future) language features. Facilitated improvement of code organization at large, introduced full stack low cost structured logging and vertical semantic namespacing, cross IDE builds. Facilities migration from paper based workflow to digital one, organization of hierarchy of Kanban boards. Overall, did much to improve our development velocity; but same time developed some game features, but not touched visuals yet.

Optimized system scaling, data ingestion and access performance on 20TB+ of indexed data. Used several data storages(relational, document, files, queue, cache). Improved teams capability to produce better code and documentation to fill ongoing and future needs, coding practices across solution, distributed collaboration and communication by introduction and effective usage of modern tools. Created e-Discovery hardening data set in my free time. Did work to replace distributed lock based flows into lock-free event-sourced flows to deliver better performance and correctness, disentangled cases where we could use eventual consistency and approximations, and where not.
