Software Engineer 🔥

Kyiv · $3500 · 4 years of experience · Upper Intermediate

Got experience in: • Big Data - 2.5 years(pipelines migration from old tech(Hadoop, Hive) to the new one(Spark, Airflow, BigQuery SQL), new ETL pipelines development from scratch; • Backend development (Java and Spring) - 1.5 years - shipped to production cloud microservice system for US legal firms; designed and implemented the main part of the new REST API for the R&D company in the automotive area. Got experience in interviewing(around 10 persons). Programming languages: Java, Scala, Python DB: Relational(Postgre), Non-relational(HBase, BigQuery) Tools: Spring, Hibernate, Hadoop, Spark, Kafka Processing engines: Airflow Version control systems: Git Build tools: Maven, Gradle Cloud Platforms: a little bit of GCP, a little bit of AWS

Java, Spring, Maven, Hibernate, Git, Scala, HBase, Hive, Apache Spark, Python, Big Data, Hadoop, PostgreSQL, Kafka

Like to do performance optimizations in bottleneck areas of systems/application, so already decreased execution time (30-300 %) or resource usage(20-40%) for a few web apps/ETL. Helped in DWH migration(about 1000 tables) from different data sources to new DWH on top of BigQuery. Like to do and have experience in software design.

I'm looking for an interesting project and ready to deal with back-end or data processing. Not interested in Java EE legacy project or front-end development. The most desirable project will be the one with a cool team and interesting domain area. Ready to start in the next week, maybe ASAP(but I am not sure for 100%)

Senior Backend Developer

Kyiv · $5000 · 10 years of experience · Upper Intermediate

For the last five years I working with Scala projects in position of lead developer. I have successfully delivered a number of web products and services. Libraries I use is bare minimum for task to be solved, namely akka-stream, akka-cluster, key-value store, zio.

Scala, Akka, NoSQL, Haskell, Java, Functional programming

Latest achievement I have is gradual migration of project which had required a dozen of senior developers to simpler solution which now can be maintained by couple of middle ones. All changes were done on production systems and clients have very positive feedback about changes. Bugs and performance issues have become a rarity. Along the way the product expanded its functionality and introducing of new features takes of magnitude less time now.

Разработчик Scala

Remote work, Russia · $700 · 1 year of experience · Upper Intermediate

Проходил стажировку на позицию Java Developer в Thumbtack. На стажировке использовал технологии Java стека - Spring framework, Boot, Hibernate. В плане окружения и деплоя использовал Docker, Jenkins, GitLab. Последние 5 месяцев работаю на backend'ом в такси на ЯП Scala. Микросервисная архитектура с использованием Scala стека - Akka, Cats, Slick, Circe... Микросервисы общаются по HTTP (Akka). Для разработки решений использовал подходы CQRS and Event Sourcing. Хотел бы найти удаленную работу для дальнейшего роста и получения новых навыков.

Scala, Akka, Git, Linux, Functional programming, PostgreSQL, Sbt, Docker, OOP, REST API, JSON, Cats, Slik, Microservices, Jenkins, Java, Spring, Spring Boot, Hibernate

Обучился основам Scala меньше, чем за месяц. Довольно быстро изучаю новые технологии. Разработка микросервисов.

Очень важна возможность удаленной работы - это ключевое, из всего резюме.

I'm a software engineer with a strong background in modern backend technologies and a keen desire to continue improving my knowledge and skills in Scala and Big Data. The GoF Design Patterns help me make a flexible and maintainable design, the principles of Clean Code and FP guide me to write concise and readable code, IoC makes my code loosely coupled and testable, and TDD guarantees that the code does what it's expected to do. I’m a good team player and I always do my best to answer questions and share my knowledge with other team members. I reviewed the existing data model of the main storage, investigated and proposed changes according to the best practices of the Cassandra data modeling in order to improve query performance. I used optimization techniques to improve Spark job performance and in some cases eliminated OOM errors. I've acquired hands-on experience with multiple distributed systems and technologies during: * participation in multiple PoC projects; * taking part in technical discussions with other engineers and the DevOps team about the proper configuration of Kafka, Cassandra and Spark clusters; * investigating problems in production data processing pipelines built on top of Microservices and Spark streaming jobs.

I have a passion for functional programming and distributed systems, so I’m looking for a project that would benefit from my knowledge and skills in a Scala ecosystem (Akka, Cats) and a wide range of modern fault-tolerant, scalable systems for building real-time high-load applications (Spark, Kafka, Cassandra, Solr, AWS, GCP). Such a project would be developed by a team adhering to the best practices and methodologies of software design and development. I’m a quick learner and curious to learn new technologies, especially in the areas of streaming stateful processing (Flink) and performing analytics on large volumes of data (ML, Deep Learning).
