What I'm looking for

I am particularly attracted to organizations that foster a culture of continuous learning, recognizing the ever-evolving nature of the tech industry. A company that encourages and supports professional development aligns with my commitment to staying ahead of the curve.

With over 5 years of experience in backend development and a strong foundation in Computer Science, I design and deploy scalable, resilient systems using Java and Spring Boot, often in cloud-native environments. I’ve delivered solutions across various industries, including real estate, logistics, construction, and finance, architecting microservices and APIs on AWS that support high-throughput, mission-critical operations. By leveraging cloud services like EC2, RDS, and API Gateway, I ensure robust, secure, and fault-tolerant deployments. I emphasize clean, maintainable code and build systems that are both technically sound and strategically aligned with business goals.

I’ve led high-impact initiatives that significantly boosted system performance, reliability, and integration. I architected a logistics module that streamlined operations, developed APIs that automated data ingestion from external sources, and optimized platforms that process large-scale structured data to accelerate analytics and improve decision-making.

I bring a product-driven mindset to backend development, consistently aligning engineering decisions with business value. I thrive in Agile teams, facilitate technical discussions, and lead by example through thoughtful code reviews. I take full ownership of the solutions I build, and I’m deeply committed to mentoring teammates, fostering engineering best practices, and driving continuous improvement across both systems and workflows.
