AirAsia — Data Engineer

August 2022 – April 2026. Joined as Data Engineer I, promoted to Data Engineer II in August 2024. 3.5 years building ETL pipelines, LLM tooling, and operational dashboards.

I joined AirAsia as a Data Engineer and have spent the time building and scheduling ETL pipelines that move data between operational systems, vendor sources, and our data warehouse — and increasingly, owning end-to-end projects that put that data in front of the people who make daily operational decisions.

🛠 Selected projects

• Cabin Crew Operational App. Integrated data from Google Sheets and BigQuery into a centralised application serving 5000+ flight crew members — putting key performance metrics directly in the hands of the people they describe. Built the multi-source ingestion pipelines (→ Postgres) and the Airflow DAGs that keep them current.

• Automated Training Tracker. Built an end-to-end workflow that monitors compliance and training schedules for 60+ operations staff and automatically emails escalations when training is overdue. Eliminated the manual chase entirely.

• Data Democratisation via LLM Tools. Spearheaded internal LLM tooling that integrates 6+ core operational modules (ancillary sales, aircraft availability, etc.) so non-technical staff can self-serve analytics. Built the supporting pipelines and AppScript automation in Google Sheets.

• Aircraft On Ground (AOG) Recovery Foundation. Built the data foundation feeding clean datasets into the operations research team’s heuristic recovery models — directly supporting how AirAsia mitigates critical operational disruptions.
  SQL ETL Airflow

• NPS Dashboard. Built the ETL pipeline behind the Net Promoter Score dashboard the customer happiness team uses to track passenger sentiment. Used the Google Translation API for multi-language reviews and Gemini for sentiment + keyword extraction (powering the dashboard’s word cloud).

• Ground Operations Dashboards & Bot. Built an automation that logs into Tableau, screenshots configured charts (e.g. flight load factor), and emails them to stakeholders on a daily cadence for operational decision-making.

• Automated Crew Bag Tag. Designed the SQL filtering logic — coordinating with the data science and data analytics teams — that the software engineering team consumed to automate the layover check-in process for crew.

• Navitaire Logging Pipeline. ETL pipeline that extracts data from BigQuery and lands it in GCS for audit purposes.
  Python BigQuery GCS Airflow

• Disaster Recovery Exercise. Annual DR participation for a major operational platform — validating recovery procedures across the data pipelines and dependent systems.

⚙️ Core platform work

• Google Sheets → BigQuery ingestion with Python ETL on a schedule.
• Database → Warehouse pipelines — Postgres, MS SQL, and other operational databases into the data warehouse.
• Stored Procedure → BigQuery — execute SP on source, transfer result.
• SFTP ingestion + reverse exports — pick up files, transform, load to BigQuery; reverse direction (BigQuery → SFTP CSV) for downstream consumers.
• Airflow scheduling and monitoring for all of the above.
• LLM experimentation — exploring how ChatGPT and Gemini speed up ETL development (boilerplate, schema debugging, doc drafting).

🤝 Other contributions

• Mentored new team joiners. Helped them ramp on the codebase, internal tooling, and team conventions — pairing on early pipelines and reviewing first PRs so they could ship confidently from day one.
• Led 10+ knowledge-sharing sessions across the department, covering pipeline patterns, tooling decisions, and lessons learned from completed projects — turning individual learning into shared team capability.
• Documented every shipped project on Confluence as a default practice, not an afterthought — the goal being that anyone joining six months later can pick up the context without needing me in the room.
• Co-organised department townhalls — helping shape the agenda, coordinate logistics, and curate content so each session genuinely served the team rather than ticking a calendar box.

Outside of work I also build personal projects to go deeper on the tooling — see Projects.

Huawei Malaysia — Management Trainee

Until 2021. A structured rotational program at Huawei’s Malaysian subsidiary, anchored in the B2B Channel Sales department — my first role inside a global technology MNC.

B2B Sales Channel Sales Pre-sales Tender Management Stakeholder Management Cross-functional

The rotation gave me a grounded view of the commercial side of an enterprise product cycle — sales-led, but cross-functional in practice. Most weeks bridged product, supply chain, and customer-facing work for partners across the Malaysian channel.

🛠 What I worked on

Product Presentation & Sales Enablement

• Prepared presentation decks and product price lists for client-facing meetings.
• Pitched to prospective clients and led product demonstrations during sales engagements.
• Delivered product training sessions to clients’ internal sales teams on newly launched lines.
• Hosted webinars introducing new product launches to prospective channel partners.
• Handled queries on product features, configurations, and use cases.

Proposals & Tender Submissions

• Matched Huawei’s product portfolio against client requirements to recommend the right configuration.
• Drafted submissions for tender projects — both the technical and commercial sections.
• Drove cross-functional alignment with internal teams to confirm proposed products were available, deliverable on time, and accurately scoped.

Order Processing & Partner Onboarding

• Issued product quotations to prospective clients.
• Processed purchase orders (POs) and issued the corresponding invoices.
• Coordinated stock delivery scheduling with clients and internal logistics for on-time fulfilment.
• Onboarded new business partners into Huawei’s internal customer-registration systems.

When the contract wrapped in 2021, I made the deliberate move out of the commercial track and into data — enrolling in the MSc Data Science & Business Analytics at APU later that year.
