- Developed a legal document management web application featuring pre-trained Small Language Model (SLM) and applied Legal Entity Recognition (LER) modules to streamline legal document workflows. - Developed using React and Typescript for the application while creating a optimized Qwen2-7b model focusing on performance and context-management, relying on RAG/vectorized DB/hybrid approach practice using BERT to help extracting information while giving context to Small Language Model (SLM). - Implemented security, compliance, and risk management features aligned with ISO/IEC 27001, ISO/IEC 27002, and NIST frameworks to the web application by creating audit and monitoring features.

- Led an internal project for annual meeting summary applications with a structured unit testing and development process using .NET while learning how to create structured unit-tests and scenarios to tackle future security issues. - Built CI pipelines with automated report generation powered by Cobertura, achieving ~97% unit test coverage using xUnit and Moq, reducing regression risk and fulfilling UAT requirements. - Designed clean RESTful APIs architecture with end-to-end security practices, including rate limiting, MIME validation, and XSS protection with the help of QC CI/CD automated pipelines.

- Revamped 5 websites using React/Typescript/Node, improving average load time by ~35-40% and enhancing SEO indexing, contributing to increased traffic and supporting company MoM growth and delivered more projects. - Optimized a website performance by lazy-loading heavy modal dependencies (AWS S3 via next-s3-upload), reducing initial client JS payload (~10-30%) and improving navigation responsiveness (~300ms-1.5s). - Fulfill the total of ~IDR 23 million worth of projects and real clients requirements, working with Project Managers, UI/UX Designer, and stakeholders. - Learn to develop a secure payment system by using Xendit SDK and gateway systems for reliable source of payment systems, while creating optimized automated cron job payment reminders and handling race-conditions, double-entry, and payment validation issues.

- Led development of e-commerce platforms using Next.js/GraphQL APIs and integrated API Shopify services for product selling while collaborating closely with stakeholders. - Delivered and revamped 2 websites with ~96% average Lighthouse performance and optimized SEO indexing helping the exposure of the company. - Experienced as a part-time Project Manager as well, by planning and researching the context of the whole IT projects in.

- Built type-safe REST APIs with Go, GORM, and OpenAPI for a competition website with 5 competitions and events with over 4000+ active users. - Implemented unit testing (~80% coverage) to improve API reliability and reduce regression risk.

- Contributed as lead and member to build frontend architecture for HMIF-Broadcast App and HMIF-App with 20+ developers while successfully integrated REST APIs and built a CI pipeline for a type-safe frontend code using Vue. - Improved internal workflows and member-facing features, reducing task execution time from minutes to seconds for event information retrieval, task management, and broadcasting.
