PROBLEM

Small F&B vendors wanted a QR ordering flow that didn't hand a cut of every sale to a payment processor, but still needed live order tracking and a vendor console that didn't feel like an afterthought.

INVESTIGATION

Mapped the flow around a fee-free path first — scan, cart, client-generated PayNow QR — then layered a real-time channel on top so both sides see the same order state without polling.

SOLUTION

Built a QR ordering & payment PWA with a Pusher-powered live queue for the vendor console (orders, menu, categories), bilingual EN/中文 support, and an optional HitPay integration for merchants who want automated reconciliation and card payments.

PROBLEM

Lecture materials pile up as unstructured slides and notes; turning them into quizzes that actually test the material — not just plausible-sounding questions — usually means manual work or an LLM that quietly hallucinates.

INVESTIGATION

Retrieval on raw lecture text showed the usual thin-RAG failure mode: keyword search missed paraphrased concepts, and pure vector search surfaced fluent but ungrounded matches.

SOLUTION

Built SynapseQ, a full-stack platform (FastAPI + Vue 3) that ingests lecture materials, builds a searchable topic hierarchy, and generates grounded MCQ quizzes through hybrid retrieval (Qdrant + BM25) feeding a multi-stage LLM generation pipeline.

PROBLEM

Keeping a social presence on-voice and current means someone has to watch AI news, decide what's worth posting, write it up, and hit publish — every day, without fail.

INVESTIGATION

Broke the job into independent stages rather than one monolithic script, so each part could be tested, swapped, or rerun on its own without touching the rest of the pipeline.

SOLUTION

Built an agent-skills-based automation pipeline (Node.js + Claude API + OpenClaw) with four independent SKILL.md-defined modules — fetch, format, queue, post — that let the agent autonomously discover AI news, draft on-voice tweets, and schedule posts to Twitter/X.

PROBLEM

Deploying an ERC-20 token contract normally means a dev environment, hand-edited constructor parameters, and a deploy script — too much friction for testing configurations quickly.

INVESTIGATION

The friction wasn't the Solidity itself — it was the round-trip between "I want to change one parameter" and "the contract is live on-chain."

SOLUTIONBuilt a Telegram bot that deploys ERC-20 token contracts with different configurations on request, collapsing the edit-compile-deploy loop into a single chat command.

PROBLEM

On Friend.tech, being early to a new influencer's key sale mattered more than almost anything else — and manually watching for new joins didn't scale past a handful of accounts.

INVESTIGATION

Needed a way to detect new joins and flag influencer accounts fast enough to act before the price moved, without babysitting a dashboard.

SOLUTIONBuilt a bot that detects new joins and influencer accounts on Friend.tech in real time and auto-buys according to configurable rules — budget caps, take-profit/stop-loss thresholds, and more.
