Adri Kaufmann

I’m a full-stack software engineer with extensive experience developing and deploying applications across telecommunications, waste management, retail, and construction. I bring hands-on expertise in Java Spring Boot, .NET, ReactJS, VueJS, Laravel, Next.js, GoLang, and PHP, with the goal of turning product ideas into working systems.

In my current freelance R&D Senior Software Engineer role, I spearhead rapid prototyping and production deployments for an Innovation Lab. I engineered a secure, scalable Psychometric Testing Platform with a RESTful Java Spring Boot backend and a responsive ReactJS + Tailwind CSS frontend, and I built internal tools that improved lab productivity and project velocity.

Previously at PT. FPT Software Indonesia, I served as Technical Leader & Senior Software Engineer. I led waste management system development (EvoSmart, EvoWaste Web Admin, and license-related web tooling), developed with Java Spring Boot and ReactJS, and managed CI/CD through Azure DevOps or GitHub Actions—deploying services on AWS with EC2 and handling S3 file workflows.

I also enjoy complex integrations: at PT. Firstwap International, I built backend solutions for a 5G Core Network Platform using Java Spring Boot and integrated Java services with C/C++, Node.js, and Python for telecom systems. Across roles and cultures, I collaborate closely, apply Agile Scrum and disciplined code review practices, and keep my stack modern through ongoing technical R&D.
