About the Conference

We're hosting Trustly.dev/2025 – our first internal developer conference, focused on AI in codingand you're invited!

A full day of technical talks and discussions about AI-assisted development. We're bringing together developers from Stockholm, Örebro, Lisbon, Izmir, and Paris to explore how AI is changing the way we code.

This isn't about hype – it's about understanding the technology, learning from each other's experiences, and figuring out how to make AI assistance work effectively in our workflows. And of course to meet colleagues and have fun!

The whole day and evening takes place at Agdas på hörnet (Agda's on the corner) where we will also have lunch and dinner. If you can not attend in person we will have live streaming of all sessions during the day.

In the evening, we will have informal Bird of a Feather (BOF) sessions where anyone can present or discuss anything they want to share. So please bring something yourself to share, it can be slides, a demo, or just a topic for discussion!

For further questions or to register something for the BOFs now, please use our slack channel #trustlydev-2025.

Ethira - Startup Founder

Speedrunning a startup with AI-driven engineering

Lucas will share insights into Ethira's journey as a startup building AI for risk management, fully utilizing AI in their coding from the very beginning.

Hear from a startup leveraging AI-assisted development from day one, the challenges faced, and the benefits gained from integrating AI into every aspect of the development process.

  • Secure software development with AI
  • Productivity hacks
  • Code hygiene

How an Agentic Coding Assistant Works

Göran dives into the internals of agentic AI coding assistants – what's actually happening under the hood? This technical exploration will give a taste of the LLM protocol used by coding assistants and highlight different challenges in implementing agentic tools like Claude Code.

Having an understanding of how the tools work makes it easier for us to know how to use them. This is an area of frantic innovation and there is now an abundance of tools available to us developers.

  • OpenAI API
  • System prompt composition
  • The agentic loop and context management
  • Sub agents and tool calling
  • Code base indexing

LLM Protocols and LLM Routers

When large language models move into production, reliability and cost efficiency quickly become central concerns. This talk looks at the practical infrastructure layer that makes LLM systems dependable and affordable. We will explore how routing and failover between different model providers actually work, how to handle provider-specific error codes, and how to design systems that continue to function when models or endpoints fail.

The session also covers caching and request optimization strategies that help reduce costs without sacrificing performance, and the trade-offs between managed SaaS solutions and self-contained environments like Bedrock.

  • Model routing and failover mechanisms
  • Handling provider-specific error codes and inconsistencies
  • Designing reliable and observable LLM agents
  • Caching and request optimization to manage cost

PingCAP

AI, Scale, HA and Databases

AI solutions are composed of many different components, and data handling is a center part of it. The session will cover several components, like Large Language Models (LLM), Semantic Search, Vector embeddings, Retrieval Augmented Generation (RAG), Model Context Protocol (MCP), and how a database can be serving the different components.

The session will also address challenges of High Availability and Scalability, using TiDB's architecture as an example how a modern database meets these demands.

  • AI components explained, LLMs, Vector embeddings, RAG, MCP
  • Database requirements for serving AI agents
  • HA and Scaling of a modern Distributed SQL database, TiDB

What Happens Now?

Jonas tries to connect the dots on what happens when AI takes a major part in software development. This closing talk will synthesize the day's insights and learnings and look toward the future.

What are the strategic implications of AI-assisted development. What does it mean for me as an engineer and what does it mean for Trustly as a company? Hopefully this session will leave you will some answers to all the questions you have.
