  • Support REG and related HKDSE systems, including application development, maintenance, incident resolution, enhancement implementation, UAT support, documentation, and production deployment preparation.
  • Handle user-reported enquiries, bugs, and incidents by analysing application logic, Oracle SQL, stored procedures, logs, and system behaviour to identify root causes and implement fixes.
  • Take ownership of REG issues from investigation and resolution to completion reporting.
  • Communicate directly with user departments such as SEAD and FD to clarify enquiries, explain system behaviour, investigate issues, and confirm resolution.
  • Analyse raw or incomplete user requirements and translate them into workable system solutions, including business-rule clarification, edge-case handling, user flow design, testing, and implementation.
  • Support internal deployment procedures, including patch review, SQL script consolidation, technical documentation, audit-related documents, and production release preparation.

Selected Achievements & Project Highlights

REG Incident Resolution – Demand Note / Late Payment Fee Issue:

Investigated an FD-reported incident where candidates received demand note / late payment fee emails but corresponding fee records were missing in REG. Traced the issue across Java batch logic, Oracle stored procedures, logs, and transaction rollback behaviour, and identified that emails were sent before database commit, causing mismatch when a later stored procedure error rolled back fee creation. Reported the root cause and proposed an enhancement so emails are sent only after successful fee creation and commit.

REG Enhancement – Subject-Specific Edit Control Rules:

Analysed complex HKDSE subject-specific edit-control rules for SEAD teams, including PE, Music, and Category C Subject. Documented different behaviours across application periods, identified inconsistent edit permissions, and proposed a clearer control approach to restrict candidate-side editing after submission while allowing authorised internal updates.

REG Enhancement – SMS Verification Function:

Supported the design and implementation of a new SMS verification function using an existing API not previously adopted by REG. Worked through practical design details including API calling approach, encrypted credential storage, OTP expiry, maximum attempt handling, candidate submission flow, and user-facing messages, and refined the UX flow so candidates receive appropriate guidance after failed verification conditions while still allowing submission according to business requirements.

Technical Initiative – Examination Centre Allocation POC:

Independently developed a proof-of-concept using Google OR-Tools concepts to explore optimisation-based examination centre allocation. Modelled allocation logic with constraints and demonstrated how optimisation techniques could support more systematic assignment planning for examination operations.
