ABOUT ME

A Mechatronics & Robotics trained engineer with track records of architecting custom automation solutions across high-compliance banking and industrial environments.

  • Specialized in: Identifying systemic bottlenecks and replacing manual friction with custom developed Python and VBA automation tools to scale engineering productivity.
  • Experienced in: Managing high-availability virtualized environments using Proxmox and Docker.
  • The Systems Gatekeeper: Operating with high-integrity 'Black Box' logic—recording the truth of a system, however messy, to ensure safety-critical stability.

CREDENTIALS

2023 — Present DBS BANK // TEST ANALYST (MANUAL / AUTOMATION)
  • Cryptographic Engineering: Engineered a custom TWQR Payment Generator using Python and DES3 Cryptography to unblock development and testing cycles by simulating secure transaction payloads.
  • Baseline Architecture: Reverse-engineered regional and global specifications to establish the first internal testing baseline for DBS's Taiwan market integration.
  • Systems Integration: Developed multi-threaded TUI and GUI applications (py_cui, Rich, Kivy) to automate data injection and sanitize complex QR payloads.
  • Early-Phase Quality: Implemented 'Shift-Left' quality checks during initial coding phases, identifying 'showstopper' logic errors before they reached system-wide integration.
  • Cross-Platform Stability: Deployed BDD-driven test suites (jBehave, Digital.ai) across SG, TW, and HK, ensuring uniform stability for retail banking apps on iOS and Android.
2022 SIEMENS SG // METRICS VALIDATOR / SOFTWARE TEST ENGINEER
  • NLP Implementation: Deployed Natural Language Processing (NLTK/Python) to parse and resolve ambiguous user inputs, transforming 'messy' field data into structured requirements.
  • BI Logic Audit: Verified Business Intelligence logic and metric definitions to ensure that high-level analytics reflected the actual mechanical truth of railway systems.
  • Big Data Extraction: Leveraged Python and HIVE SQL to manipulate and sanitize large-scale, heterogeneous datasets for LTA and ST Engineering projects.
  • Compliance Verification: Designed SIT/UAT suites to strictly align software outputs with System Requirements (SRS), maintaining safety-critical railway standards.
2021 — 2022 KEYSIGHT SG // AUTOMATED SOFTWARE TESTING CONSULTANT
  • HMI Debugging: Audited Human-Machine Interface (HMI) software using C#, identifying and debugging critical logic failures at the hardware-software interaction layer.
  • Framework Migration: Architected the conversion of legacy manual test suites into automated libraries using SenseTalk (Eggplant Functional) and Selenium WebDriver.
  • Edge-Case Auditing: Implemented aggressive negative testing to identify system behavior under out-of-scope inputs, securing the platform against unknown failure states.
  • Heuristic Validation: Designed UAT protocols to verify that automated results maintained 100% parity with legacy human-driven baselines.
2020 — 2021 OCBC BANK // TEST ANALYST (MANUAL)
  • Equities Launch: Validated and unblocked the launch of the Equities trading platform, ensuring high-integrity execution for complex financial transactions.
  • Process Automation: Engineered internal macros and Python scripts to automate redundant account setup workflows, accelerating the SIT/UAT testing lifecycle.
  • Payment Standards: Tested and implemented EMVCo SGQR mobile functions, ensuring regional payment standards were met across the mobile ecosystem.
  • Stress & Integrity: Executed rigorous stress testing on retail banking apps to identify systemic breaking points and edge-case vulnerabilities.
2020 COVID-19 NATIONAL SUPPORT // HEALTHCARE ASSISTANT / HPB SWABBER
  • National Recognition: Awarded the COVID-19 Resilience Medal for sustained commitment to national safety: No. 30448
  • Database Integrity: Managed the national COVID-19 database, ensuring high-fidelity tracking of patient records and test results.
  • Protocol Execution: Enforced rigorous bio-safety procedures in collaboration with nursing staff across multiple high-risk locations.
2019 VENTURE PTE LTD // SYSTEMS TESTER (FIRMWARE & HMI)
  • Kernel Diagnostics: Managed an air-gapped Linux testing environment; developed a custom library of Bash scripts to automate kernel-level diagnostic routines.
  • Interface Integrity: Validated specialized micro-electronics for HMI systems, ensuring signal integrity between custom hardware and control interfaces.
  • Validation Logic: Engineered novel hardware validation protocols to stress-test prototype logic, reducing manual verification cycles.
2018 — 2019 RAZER SG // TEST TEAM LEAD (HARDWARE & SOFTWARE)
  • Operational Oversight: Directed a high-throughput testing operation, coordinating a peak force of 30 testers to ensure delivery across parallel product lines.
  • UAT Architecture: Architected comprehensive User Acceptance Testing (UAT) frameworks for prototype hardware, establishing the quality baseline for global releases.
  • Efficiency Injection: Developed custom Excel Macros and AutoHotkey automation logic to eliminate repetitive manual telemetry logging.
  • Technical Liaison: Served as the primary technical bridge to design engineers, translating complex testing telemetry into actionable hardware refinements.
2018 HP SINGAPORE // SOFTWARE TESTER (PROTOTYPE SYSTEMS)
  • Environmental Stress Testing: Performed aggressive hardware-software validation on prototype systems using oscilloscopes and thermal stress environments (industrial freezers/ovens) to identify failure thresholds.
  • Defect Reconstruction: Captured and documented non-linear system bugs, recreating complex failure states to unblock firmware engineering cycles.
  • Workflow Augmentation: Engineered custom Excel Macros and AutoHotkey scripts to inject automation into manual testing workflows, increasing throughput for prototype validation.
2016 — 2018 MANUFACTURING INTEGRATION TECHNOLOGY LTD // TECHNICAL SPECIALIST (SEMICONDUCTOR)
  • Kinematic Calibration: Managed the assembly and high-precision calibration of silicon wafer 'pick and place' robotics, ensuring micron-level accuracy in high-speed manufacturing.
  • Vision System Validation: Configured and tested 3D machine vision cameras for chip scanning, bridging the gap between physical optical capture and digital defect detection.
  • Cleanroom Deployment: Executed onsite systems integration and troubleshooting at AMS Micron, maintaining rigorous cleanroom protocols while resolving hardware-logic collisions.
