Full-stack developer
I'm Đạt. DATQT Solutions is my practice, and it is only me: I take the brief, write the code, ship it and keep it running. Most of what I build sits where software meets operations and money, because I have run those departments myself.
Made entirely with AI video models. Click one to watch it with sound.
Most software fails for reasons that have little to do with code. The process underneath was never clear, nobody owned the numbers, or the tool was built by someone who never had to use it. I have managed the operations, signed off the budgets and written the code, so what I hand over is a system the people on the floor will actually use.
Sixteen things I designed, built or ran, across AI, software and operations. Pick one: most panels run a small live simulation with demo data, and the 3D and film ones play the real thing.
Staff walk up to a camera and they are checked in. The system finds the face, matches it against the people enrolled and writes the time straight into the attendance sheet. No cards to forget, and nobody can clock in for a friend.
I edit video myself, and I built the studio that does it without me. Raw footage goes in one end and a finished cut comes out the other: trimmed, colour-graded, captioned, voiced and checked for quality before a person opens the file. The film reel further down this page came out of it.
A complete photo studio in the browser: retouching, colour, cut-outs and AI edits guided by reference photos, with the brand presets built in. One person can turn a shoot into finished, on-brand images in an afternoon.
Thirty-second films made entirely with AI video models, each one a single continuous take: a mountain goat whose horns become the logo, a camera flying through a miniature company, a night drive in the brand colours. I write the shot script, design the reference frames and direct the model until the camera moves the way a real crew would.
Ask it a question and it goes to the literature, reads what it finds and comes back with a brief in which every claim points to its source. I built it for work where a wrong citation is worse than no answer.
Every app I run reaches its AI models through one gateway of my own: more than fifty models behind a single address, with a separate key for each app so cost can be traced to its source. On top sits a 3D office where agents pick up tasks and report back, which lets me review work instead of babysitting it.
One sign-in for every company in the group. People, approvals, documents, projects and reports live in the same place, with permissions that follow the org chart, so work stops scattering across spreadsheets and chat threads.
Bank transactions arrive on their own, get matched to the right invoice and land in the ledger. Bills go out with a QR code that pays the exact amount, and the tax book fills itself in as the month goes by.
A four-floor clinic rebuilt in the browser. A visitor can follow the patient journey from reception to recovery, floor by floor, and the same model carries a technical view of what sits behind the walls.
Surgical and injection techniques rendered in 3D on a realistic face: which layer is lifted, where the threads run, how the fat compartments sit. Surgeons use the clips to explain a procedure to a patient or teach it to a trainee. What plays here is the actual render.
Instruments and implants modelled, lit like a studio product shot and animated for launch videos and catalogues. There is no photo shoot to book, and every angle stays available later.
A custom launcher for the Android head unit in a 2000s SUV, and a 360 camera view with more angles and reversing lines that bend with the steering wheel. Embedded work, where the limits are a slow chip and a driver who cannot look for long.
Bids are won on paperwork that is complete and on time. I run the back office of a tender: tracking every requirement, assembling the dossier, checking each document against the list and keeping the deadline in front of everyone.
Before a renovation contract was signed, I vetted the contractors and priced what their quotes left out: lift, ventilation, fire protection, medical gas. The real cost came out around 40% above the number on paper. The same habit runs every month on recurring costs, so each payment has an owner.
Medical workshops with a university host, and large public events. I handle the part the audience never sees: approvals and paperwork with the host, a run-of-show planned to the minute, suppliers, speakers, and a plan for when something slips.
Contracts, annexes, acceptance records and payment requests all come out of one template system. The deal is entered once and the full set is generated on letterhead, numbered and consistent with each other, so nothing is typed twice.
Everything in this reel came through the studio above. It is a series of nearly thirty episodes plus spin-offs that drops a real team into the world of Journey to the West, with script, character design, motion, voice and edit all on one pipeline. That is how one person ships what normally takes a studio.

A Journey to the West role-playing game that runs in the browser with nothing to install. Nine sects, spirit beasts you hatch yourself, a tower to climb, and progress that follows you from phone to laptop. I did the game design, the code, the servers and the trailer.
Software, operations and money rarely break one at a time. I work on all three together and decide where to start once I have seen the whole picture.
I design the interface, write the front end and the back end, set up the database and the servers, and keep the thing running afterwards. AI goes in where it saves real hours: vision, language, automation.
I sit with the team until I understand how work really gets done, then rewrite the process, the sign-offs and the reporting so they hold on the busiest day. On tenders I run the paperwork side, from requirement list to submitted dossier.
I trained in financial and tax law, so I read the contract before I build the system around it. I set up records and cost controls so that money leaves the business because someone decided it should.
Open debate while the idea takes shape, strict discipline once it ships.
I studied Economics and Psychology in Prague, took a Master's in Financial and Tax Law, and worked for years across Czechia, Germany and Spain before coming home to Hanoi. Each of those left me a way of looking at a business, and I use all four on every job.
Also certified: CCIM, Six Sigma Green Belt, Lean Management Professional, Google Project Management, Certified Operations Manager, plus AI credentials from Microsoft, Google and IBM.
Some problems only show themselves on the floor, so I drive out and look.
