Can one person with AI do a whole team’s work? What live systems taught me
One person with AI can now build and ship a product that real people use. One person cannot do a whole team’s work. I’m Mo Tawfik Khalifa, chief product officer and forward deployed engineer at Instruxi. For 20+ years I have built live systems, starting at the BBC, then Formula 1, Sky, the Winter Olympics, real-time worlds for the FIFA World Cup and Expo 2020, games including PUBG, then Napster and OKX. Recently I built Laqtaa, a shared wedding photo app, on my own, and used Claude to test my code and my thesis. AI replaced the typing. It did not replace the team.
Can one person build a real app with AI?
Yes. I built Laqtaa on my own for a friend’s wedding. About 100 guests used it on the day and nothing broke.
The problem: people pay the equivalent of about $1,000 for a wedding photographer, the pictures rarely get shared, and they end up forgotten. Guests’ own phone photos scatter across chats.
The solution: guests scan one QR code and every photo lands in one shared live album. No app to install. 10 languages, including Arabic. It is live at laqtaa.app.
Before any code I wrote a 780-line brief with a hard deadline days before the wedding. On the first day, 6 milestones were built and deployed in 53 minutes. A couple of hours later the next commit read “resolve all critical runtime bugs”. Fast, then humbling.
Over 5 weeks that became 188 commits: 93 fixes and 69 features.
How much does an app like this cost to run?
Laqtaa costs about $46 a month to run, against the roughly $1,000 people pay for one wedding photographer.
That is $20 for a Vercel Pro plan, $25 for a Supabase Pro database and about $1 for the domain, and the two plans also carry my other projects.
Did Laqtaa make money?
No, and it was never meant to. It was a test of a product thesis and of market fit. I built no funnels and no go-to-market plan. It spread locally anyway, to more weddings and to friends of friends, and people still use it today. Word of mouth did that, not marketing.
What breaks when you build an app with AI?
When you build alone, what breaks is everything a team normally catches: scope, testing on real phones and the fallback plan.
Nobody said no. The brief scoped 2 languages and I shipped 10. A 3D iris animation went in and came out 10 days later. Late one night the design flipped to a new direction and back again inside half an hour. On a team, somebody would have asked why.
Bugs came back after QA was called done. The camera froze after a phone call. “Download all” crashed phones. Events were created as “open” while the database only showed “live” ones.
And no slate was loaded. In live TV, the “technical problems” slate is ready before you go on air. My brief planned 11 acceptance tests and a fallback switch. The repo ended with 1 test file and no fallback. I noticed, had no time to build it, and did not need it. That was luck. It was not a plan.
Will AI replace product teams?
No. AI replaced the typing. It did not replace the person who says no, testing on real phones, a fallback plan, or the person who catches the wrong name on screen.
At the PyeongChang Winter Olympics I worked on the transmission side of the host broadcaster’s Olympic news channel. My sticky note from that job had lines like “uplink from van 26 is weak, needs a stronger antenna” and “I need Monday off”. Every line on it was somebody else’s job. That is what a live system is: a room of people who each own one thing.
During a World Cup football match, a slug, the caption on screen, went up with the wrong player’s name. That is the mistake a live team exists to catch. Faster typing does not catch it. On Laqtaa there was one pair of eyes on the monitor. Mine.
What does a product leader do when AI does the typing?
The same job as before: decide what not to build, test on real devices, and load the fallback. When the typing is cheap, judgement is the job.
I have led teams across countries, on site and remote, for more than 11 years. At Napster I led a 24-person team of developers, designers and producers across Unreal, Unity and WebGL, including the DMCC Crypto Centre metaverse in Dubai, which we launched.
On Laqtaa I was the whole team, and the gaps showed where those people would have stood: the producer who cuts scope, the tester on real phones, the engineer who loads the slate before air.
So can one person with AI do a whole team’s work?
The building, yes. I have 188 commits and about 100 wedding guests to show for it. The catching, no. That still takes other people. If you build alone, write down who would have said no, then say it to yourself. Load the slate before you go on air. And get someone else to watch for the wrong name.
