Distributed System Expert | Java, Python and AWS Developer

am a seasoned Backend Developer with over three years of professional experience, specializing in building scalable, high-performing systems for complex applications. My career began with a solid foundation in PHP and Java, and I’ve since expanded my expertise to include cloud solutions, infrastructure automation, and performance optimization.
Previously, I worked with Traveloka, one of Southeast Asia’s leading unicorn companies, where I engineered backend solutions that made a measurable impact on business operations, particularly within the Insurance segments for the Online Travel Agency (OTA) industry. Some of my key achievements include:

• Automating reconciliation processes, resulting in a 40% increase in operational efficiency by reducing manual tasks and ensuring data accuracy across systems.
• Designing request assistance flows that boosted car insurance sales by 30%, driving significant revenue growth.
• Enhancing claim processes to reduce error refund rates by approximately 5%, ensuring customer satisfaction and operational reliability.

These achievements reflect my ability to solve business problems by developing clean, efficient, and scalable backend solutions. I am proficient in:

• Languages & Frameworks: PHP, Java, JavaScript, HTML, CSS, and modern front-end frameworks like Bootstrap.
• Databases: PostgreSQL, MySQL – skilled in optimizing queries and ensuring efficient data management.
• Cloud & Infrastructure: AWS (ECS, Lambda, EventBridge, SQS/SNS, S3, Aurora RDS, ElasticCache Redis/Memcache), Terraform for infrastructure as code, and Datadog for robust monitoring and observability.

I thrive on improving system reliability and enhancing user experiences. My experience includes building automated workflows, streamlining backend processes, and collaborating on A/B testing to improve business metrics. I believe in writing maintainable, efficient code and enjoy tackling challenging projects that require creative problem-solving.
I bring a client-first mindset, ensuring that my work aligns with both technical requirements and business goals. My experience working in high-traffic, data-intensive environments enables me to deliver solutions that are both scalable and reliable.
In addition to my technical expertise, I pride myself on being an excellent communicator and collaborator. I have mentored interns, contributed to team knowledge sharing, and worked cross-functionally with engineers, product managers, and operations teams. I’m also proactive about keeping up with emerging tools and technologies to continually improve my craft.
If you’re looking for a developer who can solve complex technical challenges, optimize backend systems, and drive measurable results, I’d love the opportunity to collaborate. Whether it’s building a new application, enhancing existing systems, or automating workflows, I’m ready to deliver solutions that align with your vision.
