TP Bank scheduling agent workflow

Full story ↓

The problem

Staff booked meetings and client appointments by hand across scattered tools. Double bookings and missed reminders were routine.

The build

A Telegram-native agent that creates, updates, and cancels bookings from natural language, checks for scheduling conflicts, and syncs the calendar in real time.

Result

Manual scheduling eliminated. Staff never left the app they already used all day.

F&B · Facebook automation

Caffe Saphie: Content & Posting System

Writes, designs, schedules, and posts on its own. Replaced a full-time marketing hire.

Caffe Saphie published Facebook post

Full story ↓

The problem

Keeping a Facebook page active with good content needed a dedicated hire the cafe didn't have budget for.

The build

A pipeline that writes on-brand copy, generates on-brand images, posts at the best times, and reviews performance daily to improve the next batch.

Result

The page stayed active with zero content staff, replacing what would have been a full-time marketing role.

Real Estate · TikTok

Market Data + Content Automation

Pulls new listings, then turns them into ready-to-post content automatically.

Automated real estate listing post

Full story ↓

The problem

Keeping up with new listings and turning them into scroll-stopping TikTok content took constant manual research and production.

The build

A system that pulls the latest listings, analyzes them, and generates formatted images and posts automatically, no research team required.

Result

Fresh, market-accurate content runs continuously with zero manual production.

Retail · Chat + Social + Orders

Phone Retailer: Chat, Posting & Order System

3 jobs in 1 system. Daily workload dropped from 2 hours to 10 minutes.

Auto-posting tool built for the phone retailer

Full story ↓

The problem

The owner spent 2 hours a day answering messages, posting listings, and logging orders by hand. Order data was scattered.

The build

One system that replies to messages automatically, posts new listings across channels, and logs every order in one place.

Result

Daily operating time dropped from 2 hours to 10 minutes. Order data stays organized, freeing the owner to focus on sourcing and selling.

"Thanh is patient, sincere, and reliable. Careful and responsible in his work, and always quick to jump in and solve problems as they come up."Nguyen Truong Giang, Shop Owner

Travel · Content seeding app

Dalat Now: AI Content Seeding App

1 person now runs 800 image posts and 800 video posts in parallel on TikTok.

Dalat Now internal video studio dashboard

Full story ↓

The problem

A 7-person team spent hours a day producing images and video for content seeding. Manual production couldn't keep up with volume.

The build

An internal app combining code and AI to generate images and video, then post and manage them automatically on TikTok.

Result

Production time dropped from 2 hours to 15 minutes a day, 5x faster. A single full-time staffer now runs 800 image posts and 800 video posts in parallel.

"Found Thanh through YouTube and reached out for help with an AI content management and auto-posting system for our 7-person team. The project took 2 months because we kept asking for more, but the result exceeded expectations. We'll definitely be back for the next project."Viet Chinh, Manager at dalatnow.vn

Business · AI-built website

ASI Everest: Full Website Built by AI

Structure, copy, layout, and code, generated end to end. Client owns every line.

ASI Everest website hero section

Full story ↓

The problem

A professional website normally takes weeks with an agency, at high cost, with every edit routed through a developer.

The build

AI generated the entire site: structure, copy, layout, and HTML/Tailwind code, cutting the timeline from weeks to days.

Result

Full site shipped fast. Client owns the source code outright, no vendor lock-in, at a fraction of agency cost.

Retail · Vision AI + OCR

Shop Apple 123: Sales & Customer Service Chatbot

Closes 90% of tickets with zero humans. Saves 18M VND a month.

The build

A chatbot with Vision AI and OCR built in. It prices a used phone from a photo instantly and reads installment paperwork automatically.

Result

90% of inquiries closed with zero human involvement. 18,000,000 VND saved a month by removing 2 support roles.

Luxury Fashion · WhatsApp

Thinh Phan Tailor: Premium Concierge Chatbot

Same polished tone as a human concierge, live 24/7.

Thinh Phan Tailor WhatsApp chatbot conversation

Full story ↓

The problem

A premium tailor needed to keep a polished, responsive customer experience, but staff weren't always free to answer WhatsApp instantly.

The build

A chatbot trained on the shop's products, fitting process, and how to speak to a high-end clientele.

Result

Instant 24/7 response on WhatsApp. Tone stays premium and professional. No message goes unanswered.

"Running a premium tailoring brand takes meticulous care and total commitment. Thanh showed exactly that spirit building our AI bot. Even with third-party platform limits at the time blocking Email and Facebook integration, he kept iron discipline on the timeline and put everything into perfecting our most critical channel. That dedication makes him a technology partner we genuinely trust."Thinh Phan, Owner at Thinh Phan Tailor

Electronics Retail · Multi-intent chat

Pancake: Smart Camera Sales Chatbot

Routes pricing, delivery, complaints, and warranty into one natural reply.

Pancake smart camera shop Facebook page

Full story ↓

The problem

A smart camera shop needed to handle pricing, delivery info, technical support, complaints, and warranty claims, each needing different handling.

The build

A chatbot that classifies each question and routes it to the right logic: pricing, delivery, product photos, support, or FAQ, then merges it into one natural reply.

Result

24/7 coverage with no staff on standby. Multiple request types handled in a single conversation thread.

Internal · Content operations

Content Agent: Multi-Platform Command Center

Manages, analyzes, and grows content across 4 platforms from one dashboard.

Content Agent analytics dashboard

Full story ↓

The problem

Managing content across TikTok, Facebook, YouTube, and Instagram meant switching between 4 different apps just to see what was working.

The build

A dashboard that tracks posts by status across every platform, shows engagement and reach in one view, runs a daily research pipeline that summarizes new content and syncs it to Obsidian, and auto-detects keyword comments to reply and DM automatically.

Result

Every platform, every post, every number, in one screen. No app-switching.

Internal · Voice-controlled ops

Contentta Console: A Jarvis for the Agency

Clap twice, talk in English, run the business. Type in Vietnamese when talking isn't an option.

Contentta voice-controlled console

Full story ↓

The problem

Running projects, clients, daily logs, and finances across scattered tools and tabs slowed everything down.

The build

A voice-controlled console covering Daily logs, Meetings, Projects, Clients, Team, Content, Marketing, Finance, and SOPs, pulled live from the Obsidian vault, plus 12 client projects synced from Supabase.

Result

One voice command replaces a dozen clicks across a dozen tools.

Internal · AI video editor

Contentta Studio: Script to Cut in Minutes

AI writes the script, then edits the raw footage into a finished short.

Contentta Studio video editor interface

Full story ↓

The problem

Producing short-form video end to end (script, shoot, edit, subtitles) took hours per video.

The build

An app that writes a fast-paced script with a numbered b-roll shot list before filming, then after filming auto-transcribes, cuts jump-cuts, splits scenes, and generates AI b-roll that matches each scene's caption and timing.

Result

A full script-to-export pipeline in one tool. No separate editor needed.

02 / About

I studied Psychology, not Computer Science. It shows in how the agents talk to customers.

Contentta started in January 2024. I run every discovery call, every build, every handover myself. No account manager between me and the problem.

15+ businesses across banking, retail, F&B, fashion, real estate, and travel are running systems I built. Still running today.
