I will design the system architecture for your saas, fintech or cloud platform
Chris A.
About this gig
Building on the wrong architecture is the most expensive mistake a software project can make. I design systems that avoid the rewrite.
For 15 years I have architected event driven microservices, multi tenant SaaS platforms and serverless backends on AWS for fintech, telecom and ERP products, as CTO and head of engineering.
What you get:
- Architecture document with component diagram, data flows and technology choices
- Data model and database design for MySQL, PostgreSQL, DynamoDB or MongoDB
- Messaging and integration design with RabbitMQ, SQS and SNS or REST APIs
- Infrastructure layout for AWS or Azure with Docker, Kubernetes or Lambda
- Scaling, security and GDPR considerations written down
- Risks, trade offs and a phased delivery plan your team can follow
Also available: a review of your existing architecture with recommendations, or a scalability audit before a launch or funding round.
Packages range from a review of your current design to a full architecture for a new platform with a proof of concept of the core flow.
Message me first with a short description of the product, expected load and current stack. I reply with questions and a fixed quote.

Former CTO offering senior backend and architecture work. For 15 years I have built fintech platforms for loans, cards and payments, multi tenant SaaS and ERP systems, and event driven microservices on AWS with Python, PHP and Node.js. I handle system design, production code, Terraform, Docker and CI pipelines, and I integrate Claude and OpenAI into existing products. Clients get a clear plan, realistic estimates and documentation they can hand to their own team. Fluent in English, German and Bulgarian.
FAQ
What do I need to provide before you start?
A short description of the product, who uses it, expected load and your current or preferred stack. For a review, read only access to the repository or your existing diagrams.
Which format is the architecture document delivered in?
A PDF or Markdown document with diagrams as images, plus the editable diagram sources, so your team can keep it updated.
Can you also build the system you design?
Yes. Backend development is a separate gig on my profile, and the Premium package here already includes a working proof of concept of the core flow.
