Engineering deep dives on AI and automation for e-commerce in Vietnam — from Shopify listings and Zalo chatbots to ViettelPost pickups, compliant e-invoices and video that survives cable cuts. Written from projects we build, not press releases.
Listings, chat, shipping, invoices and marketing on autopilot — the full architecture, and the traps that only show up in production.
On-premise and EU-boundary language models for regulated firms, governments and anyone who must govern their data entirely.
From one supplier photo and a fact sheet to a complete bilingual listing — staged for human approval.
Per-language keyword clustering, diacritics, hreflang pairs and a Search Console feedback loop.
A single LLM service behind channel adapters — grounded answers, order lookups, human escalation.
The full partner API flow — auth, order creation, pickup booking, A6 labels, COD fields, address normalization.
Docs quality, webhook reliability, COD remittance and the abstraction layer that makes the choice reversible.
Run a shop from a home or mini-storage address: automated pickups, stock sync, reorder triggers.
Decree 123 basics, field mapping, VAT rates, rejection queues and adjustment invoices for returns.
Evaluating API quality and signature handling, why USB tokens block automation, and provider abstraction.
Matching carrier remittance lines to orders, chasing unremitted cash and filing claims before deadlines.
Redirect, QR and app-to-app flows, IPN signature verification, refunds and daily settlement matching.
Decree 123 obligations, PDPD 13/2023 applied to shop data and chatbot logs, SMS brandname vs ZNS.
Webhook-driven stock sync, oversell prevention with reserve buffers, unified fulfilment and settlement.
ZNS templates through review, OA care flows in the 48-hour window, compliant remarketing segments.
Calendar as data, per-platform adapters, dedup-keyed retries and token lifecycle management.
From images and a script template to rendered ad variants in 9:16, 1:1 and 16:9 with Vietnamese voiceover.
Style guides as prompt fragments, seeds and reference images — and never letting AI redraw the product.
Northern vs Southern accents, prosody control, brand names and currency, and an STT-based QC loop.
Webhooks and nightly pulls into Postgres, a metrics layer for CR/AOV/ROAS, and an LLM that narrates — never computes.
Cable cuts, per-ISP throttling and shared-infrastructure blocks — the dual-CDN failover that actually works.
