Tech leadership on Java developers, planning, task decomposition. Communication with business. Candidates interviews. Project: System , which is de facto analogue of bill of credit, but is performed without bank license. System is built with: Java 8, Kotlin Spring Postgres JOOQ First version is released after 4.5 months of development. It is deployed into kubernetes and supports rolling updates with zero downtime. Test coverage is 92% of classes and 94% of lines. During testing there were found only 2 bugs, each of them was fixed in less then 1 hour (real fixes, not hotfixes). One of them was because of kubernetes' work with CORS. Application is being deployed with help of bamboo and helm. We're running RabbitMQ cluster (of 3 nodes currently) and Postgres in master-slave configuration with synchronous commit. React+Redux for frontend. Other responsibilities: In first month in company I've created architectural overview of whole company ecosystem. I've created presentation, where I made some accents on most influencing weaknesses of existing solutions and proposed ways to made situation better. Most of ideas from this presentation are now accepted as rules for development in company. Me and my team reviewed code of several other projects and found major transaction bugs there. Some of these bugs are now fixes, many other fixes are planned. Also we've found incorrect usage of JPA (N+1 queries and so on). I'm actively participating in hiring process — I thing that I'm participating in more interviews than any other lead. My duties are convergence of tech leading and project management — I prefer to actively participate in administrative activities — planning, prioritising, team motivation and so on.
