Design, development and delivery of scalable backend, data-driven and search-oriented solutions in a hybrid environment combining On-Premise platforms, Azure-hosted applications and GCP-based data services. Key responsibilities and achievements ● Work within a technical team in an Agile environment, ensuring delivery quality, technical consistency and maintainability. ● Design and implement scalable backend services and APIs for data collection, processing, exposure and integration with internal systems. ● Work on hybrid architectures where business applications are deployed on Azure and On-Premise environments, while data processing and analytical workloads rely on GCP services such as BigQuery, Cloud Storage and Cloud Run. ● Participate in architecture decisions with a strong focus on reliability, performance, security, maintainability, observability and production readiness. ● Define and promote software engineering best practices: clean code, automated testing, code reviews, static code analysis, performance monitoring and CI/CD industrialization. ● Review code and technical designs to ensure scalability, maintainability, testability and alignment with project architecture. ● Collaborate closely with architects, product owners, developers, DevOps teams and business stakeholders to transform requirements into robust technical solutions. ● Design and optimize search and indexing systems using Elasticsearch, Lucene and large-scale data processing patterns. ● Contribute to cloud and infrastructure automation practices using Docker, GitLab CI/CD, Jenkins, Ansible and Terraform. ● Support production-oriented analysis, performance investigations, incident resolution and continuous improvement of existing systems. Technical environment Java 8/17/21, Spring Boot, Spring Security, REST APIs, Python, Elasticsearch, Lucene, Qwazr, Kafka, BigQuery, SQL Server, React, Docker, GitLab CI/CD, GCP, Azure, Cloud Run, Cloud Storage.
