Introduction #
Imagine being a developer who wants to explore the potential of language model-based agents (LLM). You might have heard about how these tools can revolutionize the way we interact with technologies, but until you try building one yourself, it’s hard to fully grasp their potential. LLM agents are like riding a bike: they seem simple in theory, but it’s only by getting on the saddle that you truly understand how they work. This article will guide you through the process of creating an LLM agent, showing how accessible and powerful this tool is.
LLM agents are becoming increasingly relevant in the current technological landscape. According to a recent study, the AI-based agent market is expected to grow by 30% annually over the next five years. This means that now is the perfect time to start exploring these technologies and understanding how they can be integrated into your applications. Whether you are an experienced developer or a tech enthusiast, this article will provide you with the knowledge needed to start building your own LLM agents.

This agent was able to respond to over 70% of user requests without human intervention, significantly improving customer satisfaction. Additionally, the agent allowed for the collection of valuable data on the most frequent questions, helping the company improve its products and services.
Industry Trends #
Current industry trends show a growing interest in integrating LLM agents across various sectors, from healthcare to finance. According to a Gartner report, by 2025, 50% of customer interactions will be handled by AI-based agents. This means that anyone working in the technology field should start familiarizing themselves with these technologies to remain competitive.
Practical Applications #
Use Cases #
LLM agents can be used in a wide range of scenarios. For example, a developer can create an agent to automate the code debugging process, reducing the time needed to identify and resolve errors. Another use case could be integrating an LLM agent into an e-commerce application to improve the product recommendation process, thereby increasing sales.
Who Benefits #
This content is particularly useful for developers, data scientists, and tech enthusiasts who want to explore the potential of LLM agents. Additionally, anyone working in sectors such as marketing, customer support, or healthcare can benefit from integrating these tools into their operations.
How to Apply the Information #
To start building your LLM agent, you can follow the steps described in the original article. Use the APIs provided by platforms like OpenAI to create a simple agent and experiment with different features. You can find additional resources and tutorials on the Fly.io website, which offers detailed guides and code examples to help you get started.
Final Thoughts #
LLM agents represent one of the most promising innovations in the field of artificial intelligence. Their ability to automate complex tasks and improve interaction between users and technological systems makes them indispensable tools for the future. Whether you are an experienced developer or a tech enthusiast, exploring and experimenting with these tools will allow you to stay at the forefront of the industry.
In a constantly evolving technological ecosystem, the ability to adapt and innovate is crucial. LLM agents offer a unique opportunity to do so, allowing for the creation of customized and highly effective solutions. So, don’t wait: start building your LLM agent today and discover all the potential this tool can offer.

- [Everything as Code: How We Manage Our Company In One Monorepo
At Kasava, we’ve embraced the concept of “everything as code” to streamline our operations and ensure consistency across our projects. This approach allows us to manage our entire company within a single monorepo, providing a unified source of truth for all our configurations, infrastructure, and applications.
Why a Monorepo?
A monorepo offers several advantages:
-
Unified Configuration: All our settings, from development environments to production, are stored in one place. This makes it easier to maintain consistency and reduces the risk of configuration drift.
-
Simplified Dependency Management: With all our code in one repository, managing dependencies becomes more straightforward. We can easily track which versions of libraries and tools are being used across different projects.
-
Enhanced Collaboration: A single repository fosters better collaboration among team members. Everyone has access to the same codebase, making it easier to share knowledge and work together on projects.
-
Consistent Build and Deployment Processes: By standardizing our build and deployment processes, we ensure that all our applications follow the same best practices. This leads to more reliable and predictable deployments.
Our Monorepo Structure
Our monorepo is organized into several key directories:
- /config: Contains all configuration files for various environments, including development, staging, and production.
- /infrastructure: Houses the infrastructure as code (IaC) scripts for provisioning and managing our cloud resources.
- /apps: Includes all our applications, both internal tools and customer-facing products.
- /lib: Stores reusable libraries and modules that can be shared across different projects.
- /scripts: Contains utility scripts for automating various tasks, such as data migrations and backups.
Tools and Technologies
To manage our monorepo effectively, we use a combination of tools and technologies:
- Version Control: Git is our primary version control system, and we use GitHub for hosting our repositories.
- Continuous Integration/Continuous Deployment (CI/CD): We employ Jenkins for automating our build, test, and deployment processes.
- Infrastructure as Code (IaC): Terraform is our tool of choice for managing cloud infrastructure.
- Configuration Management: Ansible is used for configuring and managing our servers and applications.
- Monitoring and Logging: We use Prometheus and Grafana for monitoring,](posts/2025/12/everything-as-code-how-we-manage-our-company-in-on/) - Go

The HTX Take #
This topic is at the heart of what we build at HTX. The technology discussed here — whether it’s about AI agents, language models, or document processing — represents exactly the kind of capability that European businesses need, but deployed on their own terms.
The challenge isn’t whether this technology works. It does. The challenge is deploying it without sending your company data to US servers, without violating GDPR, and without creating vendor dependencies you can’t escape.
That’s why we built ORCA — a private enterprise chatbot that brings these capabilities to your infrastructure. Same power as ChatGPT, but your data never leaves your perimeter. No per-user pricing, no data leakage, no compliance headaches.

FAQ
How can AI agents benefit my business?
AI agents can automate complex multi-step tasks like data analysis, document processing, and customer interactions. For European SMEs, deploying agents on private infrastructure with tools like ORCA ensures that sensitive business data never leaves your perimeter while still leveraging cutting-edge AI capabilities.
Are AI agents safe to use with company data?
It depends on the deployment. Cloud-based agents send your data to external servers, creating GDPR risks. Private AI agents running on your own infrastructure — like those built on HTX's PRISMA stack — keep all data within your control. This is the safest approach for businesses handling sensitive information.
