AI Agent Development
AI agents that do the work, not just talk about it
Agents are AI that acts: researching, triaging, updating systems and completing multi-step tasks across your tools. We build them on Claude and OpenAI with the guardrails, permissions and oversight that make autonomy safe for a real business.

Chatbots answer questions. Agents finish tasks.
Most AI deployments stop at conversation: the model explains what to do, then a human does it anyway. The real leverage arrives when AI can safely complete the task itself: pull the data, make the routine decision, update the system, escalate only what genuinely needs a person.
Building that safely is an engineering discipline. Agents need scoped permissions, action logs, approval gates for consequential steps and graceful failure when they hit uncertainty. We build agents your operations team trusts, because trust is what turns automation into adoption.

Real reviews from verified Fiverr clients
“Had a great experience with Devjour Tech. He built me a full website with lots of customized sections that required a professional web designer. It's tough these days to find people who can actually do what they say they can do. I am so happy I have found a developer that I know can confidently do the work that is needed. 5 stars!!”
“Great service and went above the required job! I wanted help with some specific coding and font adjustments, the coding has now allowed me to fully control the font sizing with an adjustment tool which is super helpful! Small issues with the website were also fixed. Would highly recommend if you are looking for a coding expert for your Shopify store!”
“We are very happy with the work delivered. He helped us solve several bugs and issues we had on our website and was extremely helpful throughout the entire process. Communication was always professional and efficient, and he paid great attention to detail while following all the guidelines we provided.”
“This is the second project we have worked on and I have been completely satisfied each time, the work was executed professionally and he did what he said he would do. Highly recommend.”

AI Agent Development questions
What tasks are agents actually ready for?
High-volume, rules-plus-judgment work: support triage, data entry and enrichment, routine reporting, monitoring and first-draft anything. We scope pilots on tasks where errors are cheap and volume is high.
How do you stop an agent doing something wrong?
Scoped permissions so it can only touch approved systems, approval gates for consequential actions, budget limits and complete audit logs. Autonomy is earned gradually, not granted on day one.
Claude or GPT for agents?
We use both. Claude excels at careful multi-step reasoning and tool use; GPT is strong in ecosystem breadth. The right choice depends on your task mix, and we benchmark on your real work.
How long does an agent take to build?
A single-workflow pilot agent ships in 3 to 5 weeks including evaluation. Multi-agent systems phase in from there.
