As a Full Stack Developer at Voja, I am a key contributor to the digital transformation of the company's supplier ecosystem. I architect and develop cloud-native microservices for a sophisticated travel platform serving over 50,000 users, replacing manual, error-prone workflows with a real-time, automated Supplier Portal. My work spans from building AI-driven solutions to optimizing backend infrastructure, directly impacting operational efficiency and supplier satisfaction.

• Delivered a real-time booking system featuring a GenAI-powered chatbot using the OpenAI API and advanced prompt engineering, which resolved 75% of routine support inquiries autonomously and optimized human agent efficiency by 40%.

• Architected and deployed a cloud-native microservices platform on AWS using Docker and Kubernetes, establishing CI/CD pipelines with GitHub Actions that accelerated deployment velocity by 70%.

• Resolved critical performance bottlenecks by re-architecting core components with Redis caching, resulting in a 50% decrease in latency for booking requests and a more responsive user experience. -Integrated Datadog and New Relic for real-time performance monitoring, which provided critical insights that led to a 60% reduction in average issue resolution time.

At WeTravel, I moved beyond typical development tasks to identify and solve critical business challenges through technology. Recognizing a key user pain point in the onboarding process, I proactively designed, built, and launched a comprehensive product tour system from scratch. My contributions spanned from foundational backend API development to revenue-impacting UI redesigns and team mentorship.

• Proactively identified a critical user experience gap and single-handedly engineered a complete, interactive product tour system, reducing new user onboarding time by 40% and improving first-month retention.

• Engineered scalable RESTful APIs for a serverless architecture using Python and FastAPI, achieving a 60% increase in system scalability and reducing API latency by 35ms.

• Mentored junior developers and interns through pair programming and code reviews, fostering a collaborative team environment and accelerating overall team productivity.

As the most junior member of the team at Aspera, I took the initiative to modernize the company's technical infrastructure and product offerings. I developed a real-time CrossFit management system that directly improved business outcomes and spearheaded the transition to Infrastructure as Code (IaC), fundamentally changing how we built and deployed software.

• Spearheaded the company's transition to Infrastructure as Code (IaC) using Terraform, accelerating team development velocity by 30% and cutting infrastructure expenditure by 15%.

• Developed a real-time CrossFit management application using an event driven architecture, which optimized scheduling for 200+ daily users and directly led to a 30% increase in class attendance.

• Established team-wide testing best practices by developing a comprehensive test suite, decreasing the number of bugs discovered in production by 30%.
