Read the room, then build the system.

BAC HQ

Design jobs, emails and deadlines lived in five places, and the designer and I kept chasing each other. Now one service gathers them and sends each person what they need, when they need it.

1. InputsWeb task list, work inbox (read-only), roadmap items
2. →
3. Python serviceAbout 7,200 lines. Scheduled by launchd, SQLite store, one module per topic
4. →
5. TelegramTopics for roadmap, design, mail and meetings, with a 9am digest and calendar files

• SecuritySecrets live in an untracked .env file. Only allow-listed people get answers.
• PrivacyRead-only mailbox. Bank emails show the subject only, and it refuses to store NRIC, card or bank numbers.
• ReliabilityCatches up after the machine sleeps. A dry-run mode replays a script before any change goes live.
• CostNo hosting bill: it runs on hardware the team already had.

On a cloud platformMove it to a managed container runtime with a scheduler and a secrets manager, so it no longer depends on one laptop being awake.

Campaign hub

Staff and partners kept asking which promotions were running where. The answer is now one public page that updates itself through the day.

1. One data fileEvery campaign with partner, outlets, dates and status
2. →
3. Build and redactPython generates the pages and strips anything private
4. →
5. Cloudflare PagesDeployed with Wrangler on a schedule, only when something changed

• Single source of truthThe hub and this portfolio's archive read from the same campaign data.
• Static by designFast everywhere, cheap to host, and nothing on a server to break into.

On a cloud platformDeploy from the Git repository on every change instead of a local schedule, with a simple form or sheet as the editing screen for the team.

This portfolio

Hand-coded with no framework. Adding a project means adding one entry to a list, and the video plays with your scroll on phones and desktops.

1. Data at the topProjects, roles and skills as plain lists
2. →
3. One pageHTML, CSS and JavaScript render everything from the data
4. →
5. Video layerTwo 1080p clips loaded whole into memory, mapped to scroll

• Works anywhereClips are fetched whole, so scrubbing works even on hosts without partial downloads.
• AccessibleLight and dark themes, a reduced-motion version, and swipe and back gestures on phones.

On a cloud platformServe the video from a CDN with range requests and adaptive bitrates, so the first frame arrives faster on slow connections.
