Position: Java Tech Lead
Category: Java
English level: upper
Years of experience: 8

5. Already had my hands over 3 projects here - you can tell from tech stack I mentioned :) Sometimes simultaneously as client had tough times during pandemic, but we made it through :)

4. Developing API products, maintaining services aimed for incident investigations and monitoring. My role on this project was Dev Team Lead and I had multiple responsibilities:
 - As client's company had 1000+ engineers, the API engine management was a separate job function, I was in charge. Worked with Google Apigee to ensure stability and cost efficiency in highly loaded environment (billions API calls/week)
- Provide technical guidance and integration support for 3rd party companies, from initial negotiations to complete solutions

3. Followed Waterfall methodology, acting as a self-managed engineer and reporting directly to customer I had to develop a complex ESB product. Backend team consisted of just me and project was delivered within budget and estimates, took me year and a half - started with diagram, ended with a successfully released product.

2. Experience with Java on FE and some highly specialized tools. Started as a java dev, ended up solely leading the stream till customer's contract expiration date. Took over responsibility of app design and approach to development as I was the only dev who completely mastered voice over and accessibility tools and thus conducted knowledge sharing sessions for the team. At the end of a project developers were transferred to other teams and I had an honour to finish the project along with documenting everything for the client ;)

1. My first experience in production, back then Apache Spark, Kafka, ELK and Zookeeper were relatively new and my responsibility was to develop 2 POC for the company:
- ELK-based logging and analysis solution that would replace existing proprietary tool
- Prove the practicality of Apache Spark + Spring Batch + Apache Zookeper stack for solving business problems
Successfully delivered and documented both POCs
