I will design your saas architecture and deliver a technical design document
Juampirichter
About this gig
Before you write a single line of code, get the decisions right.
I deliver the technical design document your SaaS needs: architecture, data model, security, and a build plan your team can actually execute.
WHAT YOU GET
- Architecture and data-flow diagrams, with editable source files
- Domain and state models: entities, transitions, edge cases
- Storage and database layout, with rationale for every choice
- Multi-tenant isolation and security model
- AWS service selection, argued rather than assumed
- Idempotency, retry and failure-handling rules
- A phased build plan: what to build now, what to defer
IDEAL FOR
Technical founders and small teams building a B2B SaaS who can code, but do not want to gamble on the structural decisions.
WHY NOT JUST A DIAGRAM
Anyone can draw boxes. What you buy here is the reasoning: why this database, why this queue, why this boundary, documented so your team and your future self can follow it. Every recommendation states its tradeoffs and assumptions openly.
Tell me what you are building and I will tell you which package fits.

I am a Backend Engineer with 2+ years of experience building cloud-native apps for US startups. I specialize in Node.js, TypeScript, and AWS Serverless architectures.
I write production-grade code, not no-code bots. I optimize backend latency, provision infrastructure using Terraform, and integrate advanced AI. I also built Tavia, an AI receptionist that handles restaurant reservations over WhatsApp using GPT-4o — with smart table assignment and automated reminders.
Stack: Node.js, AWS (Lambda, API Gateway, DynamoDB), Terraform, OpenAI API.

FAQ
I already have an architecture. Can you review it instead?
Yes - that is exactly what the Basic package is for.
Do I get editable diagrams?
Yes. You get rendered images plus editable Mermaid source files, so your team can modify them later.
Is this only for AWS?
AWS is my strongest area, but the design principles apply anywhere. Tell me your constraints and I will work within them.
Will you write the code too?
This gig delivers the design. I take implementation work separately - message me and we will scope it.
How is this different from a 20 dollar architecture diagram?
A diagram shows what. This document explains why, with the tradeoffs written down. It is the difference between a picture and a decision record.
