Hi, I'm Azel Thong.

Developing secure internal business applications and workflow systems with a focus on full-stack development, application security, database security, and process automation.

• Developed a secure internal Central Approval System using Next.js, React, TypeScript, Supabase/PostgreSQL, and Tailwind CSS, supporting role-based workflows for quotations, approvals, MIOs, document archiving, and audit history.
• Implemented authentication, role-based access control, Row Level Security (RLS), server-side authorization, API rate limiting, input validation, and hardened PostgreSQL RPCs to protect sensitive business data.
• Engineered a secure private document-upload architecture using signed Supabase Storage URLs, server-side MIME and file-signature validation, file-size controls, transactional metadata finalisation, and protected replacement workflows.
• Built an automated PDF archive-sorting feature using deterministic browser-side text extraction to identify MIO references, validate them against approved database records, and securely route documents.

Co-founded and operate a small food business, managing branding, marketing, product launches, fulfilment, operational planning, and customer engagement.

• Manage the brand image of the business through social media, physical advertising, and networking.
• Plan the timing of new flavour launches, seasonal campaigns, and promotional sales to maximise customer engagement and revenue.
• Optimise operational efficiency by grouping deliveries, bulk ordering ingredients, and organising production into baking batches.
• Generated more than S$10,000 in revenue to date, with S$370 donated to HabitatSingapore and the Society for the Prevention of Cruelty to Animals (SPCA).

Contributed to the development and validation of a fixed weather-station prototype involving embedded hardware, Arduino programming, sensors, and hardware-software integration.

• Developed components of a fixed weather-station prototype using Arduino programming and embedded hardware.
• Integrated and soldered electronic components to support hardware functionality and sensor connectivity.
• Collaborated with a professor and research team on system design, testing, and troubleshooting.
• Supported prototype validation by testing sensor outputs and troubleshooting hardware-software integration issues to improve system reliability.
