10x faster and reliable: rebuilding a client's AI agent as a team of agents
A client's AI agent for staffing agencies took over a minute to respond and broke roughly one time in ten with a malformed-JSON error. The client wanted me to "fix the prompt" - but the prompt was never the problem. It was architecture: one agent carrying too much work.

A Denmark-based health and well-being company used AI to write blog posts and hated the quality - it read like AI, and it was in Danish, which AI handles poorly out of the box. I built a blog-writing tool around one insight: if a human can imitate AI's style, AI can imitate one specific human's style.

A SaaS founder serving hotel renovation contractors wanted to find leads with AI. Even ChatGPT refused to read Google reviews - his plan was to hire people to read and categorize each one by hand.

A staffing agency wanted a better way for employers to find candidates than scrolling through endless filters. I added a ChatGPT-style search widget to their WordPress site: employers type what they want in plain language and instantly see matching candidates.

"You were directly pointing to the issue that I experienced."

What's your line of work?
My name is Ove André Remme. I'm located in Norway, near Oslo, and I'm the CEO of Terapivakten and Terapivakten Kurs og Kompetanse, and a treatment manager. We deliver therapeutic services to clients in Norway, along with digital courses, lectures, and talks for companies - drug-prevention and mental-health prevention courses, and therapeutic interventions. So it's an important line of work, in the healthcare industry.
Walk me through how you chose me to work with.
I have around 10 years of experience working with different freelancers through Upwork. That experience has been variable - some have been really bad, some good. But choosing you, Vlad, actually came out of failing first with someone else. I posted a project - a course builder that could create course lessons in a streamlined way - and around 30 people wanted to help. I first tried a guy who did some work building a ChatGPT agent, and I noticed Vlad's message: "You cannot make this through a chat agent, you need to do it this way." At first I thought, that's a cocky message. But eventually he was right - the ChatGPT agent the other freelancer built didn't work well enough. It didn't create long enough lessons, it sounded like AI, a lot of things just didn't fall right. So I went back to this cocky Ukrainian guy and said, "Hey, can you help me with this?" And that's how the new AI course builder started.
What impressed you most - what did I do differently?
It was your honesty. You were directly pointing to the issue that I experienced. And your patience with me. You were always communicative - I could contact you in the evening, the morning, whatever, and you were always there. You streamlined the whole process, you updated the application, you were really service-minded, focused on the solution rather than all the problems. And you gave hope and faith that this would be a perfect application eventually. It wasn't perfect from the very start - AI likes to make mistakes and hallucinate - but you perfected it along the way, finding the root cause of each issue so it wouldn't happen again. It was already better than what I had before, and you kept improving it.
What would you say to recommend me to others looking for AI services?
I would say: if you want a really responsible, serious, experienced guy who is service-minded, kind, polite, and always available, you'll go for Vlad. He knows what he's talking about.
"Vlad has been incredible to work with. Very sharp and understands the intricacies and needs of our company. Have trusted him with important tasks, and he's always been able to get creative and deliver."
Source: LinkedIn"I've worked with Vlad for almost 2 years on Sellify AI and he did an outstanding job. Vlad knows his craft well and was able to handle complex engineering tasks independently. He is quick to learn new things and adapts fast when requirements change (and in startups, they almost always change). I'm glad we had him on the team!"
Source: LinkedIn"Vlad saw what I was trying to create before I'd even fully explained it. He just got it. If you're looking for someone who understands AI and applies it practically, without wasting time - he's the one."
