You will get Data Modeling & Backend Design for Your App
Project details
Are you ready to scale your MVP to more than just a vibe-coded front end?
I’m a software engineer with a Master’s in CS and a background in product development and backend architecture. I help teams go from vague ideas or messy MVP schemas to clean, well-documented data models that are ready for implementation.
Data modeling is a mandatory step of a project and is the process of creating a visual blueprint that defines the data an organization collects, how that data is stored + managed, and the relationships between different data elements.
This project is for you if:
-You have an MVP and your database is starting to feel hacked-together.
-You’re starting a new project and want a solid schema before writing backend code.
-You want clear documentation you can hand to any developer and say: “Build this.”
What you'll get is:
-A data model / ERD diagram
-A normalized database schema (tables/collections, fields, types, relationships)
Clear notes on:
-Primary keys, foreign keys, indexes
-How entities relate (1:1, 1:N, N:M)
-Any denormalization tradeoffs (for performance or reporting)
-A short README-style document summarizing the design and how to extend it

Full-Stack + Mobile Software Developer | AI-Savvy | Product-Focused
Los Gatos, United States - 7:07 pm local time
Over the past few years I’ve:
-Built and maintained web applications and backend services
-Worked across the stack (front end, APIs, databases, cloud)
-Collaborated with teams to turn loose product ideas into concrete specs, roadmaps, and shipped features
Because I come from a product mindset, I don’t just write code and disappear. I care about:
-Understanding your goals – what success actually looks like for you
-Clear communication – regular updates, quick responses, no disappearing acts
-Good documentation – READMEs, architecture notes, and handover docs so you’re not “stuck” with a black box when we’re done
I also have up-to-date experience with modern AI tools thanks to my recent academic work in computer science and AI. That means I can:
-Integrate AI/LLM features into your app (chatbots, assistants, content tools, etc.)
-Use AI tooling to speed up development while keeping quality high
-Help you think through what should and shouldn’t be powered by AI in your product
How I can help:
-Web & application development
-API & backend development
-Technical prototypes / MVPs
-Automation & scripts to save you time
-Code cleanup, refactors, and documentation
-Provide consistent and clear communication
If you’re looking for a developer who is technical, reliable, and easy to work with, send me a message with what you’re trying to build. I’m happy to ask a few clarifying questions and suggest a concrete plan to move forward.
Steps for completing your project
After purchasing the project, send requirements so Jack can start the project.
Delivery time starts when Jack receives requirements from you.
Jack works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery (Call or Async)
A short touch-base to understand the app, the users main flow and functionality.
Model Drafting
I create a entity + relationship model of your system with appropriate types, enums, relations before sharing first-pass for notes + feedback from you.
