With over 12 years of experience in various software engineering roles—especially in software architecture, data engineering, and backend development—I specialize in building robust, distributed systems with a strong focus on microservices and event-driven architectures using Pub/Sub, Kafka, or other brokers.
In addition to my core backend skills in Java (Spring Boot), I’ve developed practical expertise in Python for data pipelines, testing, and serverless automation, and have experience across both GCP and AWS cloud ecosystems.
- Back-End Development: Java/Spring Boot 🍃, Python (REST APIs, scripting), TypeScript with Node.js/NestJS
- Data Engineering: Apache Beam (Python & Java SDK), Spring Batch, Pandas, Airflow
- Cloud & Serverless: GCP (Pub/Sub, BigQuery, Cloud SQL), AWS (Lambda, RDS, CDK - Python)
- Performance & Testing: Locust, pytest-benchmark
- Architecture & DevOps: CI/CD pipelines with Jenkins & GitHub Actions, Docker, ECS, Cloud Deploy
PostgreSQL, MySQL, Oracle, SQL Server, MongoDB, Redis, Elasticsearch
- Google Cloud Platform (GCP): Pub/Sub, BigQuery, Cloud SQL, Cloud Storage, Cloud Deploy
- Amazon Web Services (AWS): EC2, ECS, Lambda, RDS, IAM, CDK (Python)
- Distributed system design & legacy modernization
- Container orchestration and microservice security hardening
- Prompt engineering with LLMs (GitHub Copilot, ChatGPT)
