Software Engineer
My legal name is Weixi Guan. I’m from Canton (Guangzhou), China, and I bring 2+ years of professional experience in software engineering.
I work mostly on full-stack systems and AI-adjacent tooling, building AI agents and improving their capability and performance. I care more about software people actually use than software that just looks good in a slide.
Outside work, I’m usually on a bicycle or motorbike, tinkering with a side project, or trying out whatever new tech caught my eye that week.
DeepSesh
Co-founding and engineering the product from early-stage generated code into a clearer, more maintainable platform. Reconstructed Supabase database design and row-level security, improved API data request efficiency by around 40%, advised on frontend design, and used Lighthouse, Codex, Claude Code, and engineering review practices to improve performance, structure, and product quality.
Bamboo Technologies
Worked on enterprise AI and Copilot Studio projects for document understanding, policy assistance, customer persona generation, and invoice automation. Built RAG pipelines with Azure Blob Storage, Cosmos DB, Python services, SharePoint, Dataverse, Azure Content Understanding, and AI Foundry, while completing Power Platform training aligned with PL-900 and PL-400.
Tutor Lim
Conduct online or in-person tutoring sessions to university students, assisting them with assignments and homework. This includes offering study tips and guidance to help them understand and resolve problems and complete their tasks effectively.
Total Game Development
Contributed to the development of new gameplay features for the open source C++ game War of Salvation, enhancing player experience and game functionality. Identified and resolved memory management issues, including pointer related bugs and memory leaks in the Ship unit system, improving stability.
ABC Academy of Music
Engineered Java-based microservices architecture using Spring Boot and JPA to improve backend modularity and scalability. Established Jenkins CI/CD pipelines, streamlining deployments and reducing downtime significantly. Resolved over 30 functional, logical, and security issues through Agile sprints, ensuring robust application performance.
Guangdong Provincial Academy of Building Research Group Co.Ltd
Developed CRM and SaaS software using Spring Boot, Vue.js, REST APIs, MySQL, Pig4Cloud, MyBatis Plus, Alibaba Nacos, Docker, and Jenkins CI/CD. Wrote API documentation, debugged Java and JavaScript issues, and collaborated through Chandao to support customer data, interaction, and activity management.
The University of Melbourne
Royal Melbourne Institute of Technology (RMIT) University
Royal Melbourne Institute of Technology (RMIT) University
Designed and implemented an enterprise document processing solution using Azure AI Content Understanding to automate structured data extraction from application forms and invoices. The system supports both single-format pipelines and complex multi-format scenarios by training multiple extraction models and routing documents through classifier-based workflows. It exposes unified inference outputs as structured JSON for Power Automate, Dynamics 365, Power Apps, and other frontend systems.
An internal enterprise chatbot agent built for CGC Malaysia in my previous company environment. The solution connected Microsoft Copilot Studio with Azure AI Foundry and a RAG pipeline for secure knowledge retrieval, using Azure Blob Storage for document ingestion, Cosmos DB for chunk and metadata storage, PostgreSQL for RBAC/conversation data, and Azure AD for single sign-on. No public demo is available because the project was delivered inside the client and company environment.
An administration software as service (SaaS) platform for a Cargo Vessel local government company. Develop plenty of CRUD operations for the services in need from client.
Guangzhou University Instrument Sharing Management System, a web-based platform for managing the university's shared instruments and laboratory equipment.
A 1v1 terminal-based Scrabble game built in C++ with Makefile support. The project uses linked-list node structures to manage tiles and gameplay state, validates player moves, tracks scores, and recreates the core word-building experience in a terminal environment.
A practical snapshot of the tools and areas I use to build AI-assisted products, cloud workflows, and maintainable software systems.
