Cihan Dogan
I am a Senior Software Engineer with over 10 years of experience building scalable distributed systems across fintech, IoT, insurance, and gambling domains. Currently based in London, I specialise in payment systems, wallet platforms, and high-throughput backend architectures using Java, Spring Boot, and microservices.
My career spans 7 distributed projects across multiple industries, from processing over 10 million daily transactions at a payment gateway to managing 10+ microservices across 7 regions at a global gambling platform. I have hands-on experience with event-driven architectures, CQRS, event sourcing, and cloud-native development on AWS.
I hold an Oracle Certified Professional Java 11 Developer certification and a Professional Scrum Master qualification. I am passionate about building robust, well-tested systems and mentoring fellow engineers.
Local-first Software London
Local-first Software London is a community organising in-person events for those interested in “local-first” software, and other associated technologies, such as CRDTs and real-time multiplayer.
Anyone is welcome to join, our meet-ups are free and a great way to meet and share ideas with people interested in local-first.
To learn more about local-first software a good starting place is the Ink & Switch paper, the Lo-fi community and this Introduction to local-first guide.

Artificial Intelligence and Deep Learning for Enterprise
Artificial Intelligence and Deep Learning for Enterprise is a meetup dedicated to talks from people in the industry taking the most exciting developments in AI and using it in impactful, real world applications.
Our events are evenings of talks, food, and conversation with ML and AI industry pros so if that sounds like something you'd enjoy please do come along (and if you prefer, you can watch past events on our YouTube channel).
Our goal is to have the Meetup content be community-driven, so if you have a topic you'd like to discuss please get in touch! If you have a talk you're keen to present please submit it via our CFP form.
We're committed to creating a safe and inclusive community, please see our Code of Conduct for more information.
AI for Engineers London
Practical AI for Software Engineers - dev tools in SDLC, core patterns for LLM implementation
AI for Engineers London is a community for software engineers who want to harness AI to build better software, faster.
We focus on the engineering side of AI, not ML/data science, sharing battle-tested approaches, practical tools, and proven patterns that transform how you write, test, deploy, and maintain code today.
Join us for monthly meetups featuring live demos, case studies from London tech companies.
For collaborations, reach events@gitnation.org
Topics covered:
🛠️ AI-Enhanced Development & Delivery
Development Acceleration
- Code generation with Claude Code, GitHub Copilot, Cursor, and emerging tools
- Automated code reviews, refactoring, and documentation generation
- Test generation and intelligent debugging assistance
- Building with MCP servers, LangGraph, CrewAI, and agent orchestration frameworks
- Smart monitoring, alerting, and root cause analysis
- Self-healing systems and automated incident response
🔧 Practical LLM Integration Patterns
Learn proven patterns for adding AI capabilities to your applications without complexity:
Core Integration Patterns
- RAG (Retrieval-Augmented Generation): Connect LLMs to your databases and documentation to answer questions using your own data — no model training required
- LLM optimizations
- Prompt Templates & Chaining: Structure prompts for consistent outputs and chain multiple AI calls for complex tasks
- Input/Output Validation: Add guardrails to ensure AI responses meet your requirements — from JSON schemas to content filtering
And other topics within core theme of the group
