My name is Marco Antonios. I’m the founder of a small software company based in Lebanon, and most of the backend systems and infrastructure we build are written in Go.
We mainly use Go for APIs, microservices, and backend infrastructure.
Our typical stack looks something like this:
Go for backend services
MongoDB / Neo4j / Cassandra depending on the use case
Kafka and Flink for data pipelines
Docker and AWS for deployment
Flutter and Angular for frontend applications
One of the projects we’re currently building is Costguard, an OpenAI-compatible gateway written in Go that helps teams track AI usage and costs, and route requests between different AI providers.
We also previously built Dolfins, a platform that combines restaurant reservations with social features.
If anyone here is building or wants to build systems with Go and is looking for help with backend development, microservices, or infrastructure, feel free to reach out. We’re always open to interesting collaborations.
Hi Marco, Costguard caught my attention immediately. I’m a Backend Engineer specializing in Go and distributed infrastructure, and I’ve recently engineered a very similar system.
I built a high-throughput, asynchronous AI orchestration pipeline designed specifically for resilient LLM prompt processing. It uses Go, addresses external API rate-limiting/downtime via exponential backoff, and ensures at-least-once delivery using the Transactional Outbox pattern over high-frequency message streams.
My background in building low-latency Go microservices and optimizing data-layer interactions aligns precisely with what you are architectural scaling with Costguard. I’d love to connect and discuss how I can deliver immediate value to your backend and infrastructure tasks.
