AI SaaS · UK Client

Advera

From a broken codebase to an investor-ready AI video SaaS — in 7 days.

The Context: A Sinking Ship and a Ticking Clock

A UK-based founder came to me in a state of genuine panic. He had an investor meeting locked in for a high-potential AI video SaaS — think MakeUGC but smarter — and his previous developer had disappeared, leaving the codebase in pieces. The product's core feature, an AI pipeline that generates talking actor video ads on demand, was completely non-functional. The deadline was days away and trust in engineering was at an all-time low.

He didn't just need a developer. He needed someone who could read the situation, absorb the pressure, make clear decisions fast, and then go build without needing to be managed.

Triage First, Code Second

When the stakes are this high and the client is this anxious, the worst thing you can do is open your laptop immediately. I sat with him, slowed things down, and went through the roadmap ruthlessly. We cut everything that wasn't the investor demo. One feature. One pipeline. One goal: a working talking actor video ad generator, live, in 48 hours.

That clarity changed everything. He stopped spiraling and started trusting.

48 Hours

I built fast. A solid Next.js and React foundation. An async AI pipeline using LangChain pulling together OpenAI and Anthropic for script generation. FFmpeg for media rendering. AWS S3 and Cloudinary for asset delivery at speed. No corners cut on the architecture — just no time wasted on anything that didn't matter yet.

48 hours later, the pipeline worked. A product brief goes in, a professional talking actor video ad comes out. The founder watched it run for the first time and his entire demeanor shifted. He went from someone who couldn't see a way forward to someone who couldn't wait to get on that investor call.

One Week: From Demo to Product

With the hard part proven and trust fully rebuilt, I pushed through to a complete SaaS. Proper data modeling with Prisma and PostgreSQL. Authentication via NextAuth. Tier-based subscriptions and a credit system through Stripe. A UI that felt premium, not rushed. By the end of the week, Advera wasn't a demo anymore. It was a product a founder could stand behind.

"I can rely on a dev like you who communicates and delivers excellently."
