You will get a PostgreSQL or MySQL database design with ERD and SQL scripts
Project details
Building a new product or inheriting a database that no one can safely change?
I will turn your requirements into a documented PostgreSQL, MySQL, or SQLite foundation your application can grow on. The scope is confirmed before implementation, so you know exactly what is included.
You receive:
• requirements review and explicit assumptions;
• ER diagram with entities, relationships, and business rules;
• normalized tables, primary and foreign keys, constraints, and indexes;
• executable SQL DDL and migration scripts within the purchased tier;
• practical query and API integration notes where relevant;
• concise handoff documentation for your developer or team.
Ideal for SaaS, CRM, ecommerce, booking systems, mobile apps, internal tools, and clean migrations from CSV or an inherited schema.
I do not promise a specific performance multiplier or production approval without access, measurement, and a defined scope. Sensitive data should be removed from samples before sharing.

Frequently asked questions
About Vladislav
Android & Flutter Release Specialist | Google Play, Gradle, AAB
Belgrade, Serbia - 11:41 pm local time
I’m a product-minded software developer working across Android, Flutter, backend APIs, databases, integrations, and web systems. Clients come to me with blocked releases, unreliable code, unclear requirements, or a product idea that needs to become a maintainable application. I turn that into a clear technical plan and a working result.
I can help you with:
• Android/Kotlin and Flutter application development
• Gradle, SDK, AAB/APK, Google Play, and 16 KB compliance fixes
• Backend services, REST APIs, authentication, and third-party integrations
• PostgreSQL, MySQL, and SQLite database design, optimization, and migrations
• Python/Django, JavaScript, automation, and internal business tools
• Debugging, performance improvement, technical audits, and release preparation
What you can expect:
• a clear diagnosis and scope before development starts
• sensible architecture without unnecessary complexity
• tested changes and transparent progress
• direct communication about risks, tradeoffs, and limitations
• clean handoff documentation and practical next steps
I care about data integrity, performance, security, maintainability, and the business goal behind the code. If an existing solution can be repaired safely, I will not push a rebuild. If the architecture needs to change, I will explain why before touching production.
Send me your current blocker, requirements, repository details, and desired outcome. I’ll review the context and propose the safest path to a reliable release.
Steps for completing your project
After purchasing the project, send requirements so Vladislav can start the project.
Delivery time starts when Vladislav receives requirements from you.
Vladislav works on your project following the steps below.
Revisions may occur after the delivery date.
Confirm scope and architecture
I review workflows, existing assets, engine, scale, assumptions, and the purchased tier, then confirm the ERD direction.
Design the database and SQL
I create the ERD, tables, relationships, constraints, indexes, and SQL scripts included in your tier.
