BETA version of the portal for employees, core SaaS platform

Budget: 12000 UAH Deadline: 7 days

Good day. I specialize in CRM, dashboards, databases, and web services for processing, accounting, and analytics. Convenient and modern design. Development is fully turnkey. Lavarel 12.

Integration with artificial intelligence and other automations can be implemented. CRM is my main focus, so I can offer many interesting options.

Feel free to reach out.

Hello.
I am interested in creating a beta version of a backend-oriented web application for processing cosmetic formulas, generating INCI, and checking compliance with EU Regulation 1223/2009.

The project is well-defined and appears to be the core of a SaaS platform rather than a one-time solution — this is important, and this is the approach I work with.

How I envision the beta implementation

Architecture

Backend as a separate logical core (API-first);

clear separation of domains: Formula / INCI / Regulatory;

Frontend — a minimal portal for working with formulas (without business logic);

prepared for scaling (multi-tenant, country packs, additional databases).

Beta functionality

INCI generation

input of formulas in tabular form;

normalization of INCI based on CosIng;

aggregation of percentages;

correct formation of INCI for EU labels;

detection of errors and incorrect names.

Regulation 1223/2009 check

check Annex II–VI;

statuses OK / WARN / FAIL;

display of restrictions and max %;

a separate verification module without hardcoding rules.

Data

PostgreSQL with a normalized data model;

DB structure ready for connecting Raw Materials / Fragrance DB in the future;

clean business logic without tying to one type of product.

Technologies

Backend: Node.js / NestJS or Python (FastAPI) — depending on your priorities

Database: PostgreSQL

API: REST (with the possibility of extending to GraphQL)

Frontend: minimal web UI (React or similar)

Timeline (beta)

6–8 weeks, realistically:

architecture and data model;

INCI databases (CosIng);

INCI generation logic;

Annex verification module;

basic web portal;

API testing and documentation.

No "quick hacks," but with a foundation for growth.

I work carefully with regulatory logic, data structure, and long-term product support.
I am ready to discuss architectural solutions, beta format, and the further roadmap of the platform. Expand

Vlad, greetings!
I am interested in your project; our team has extensive experience in developing complex applications, particularly SaaS-oriented ones.
We implement the backend, and if needed, we can also take care of all other work as a turnkey solution.
We have a formed team from business analyst, designer, to development and testing.
Let's discuss the details.

Hello, I can develop the backend in Golang and the frontend in Vue. I have 5 years of commercial development experience and another 10 years as a business analyst/architect. We can work with flexible business rules and integrate a simple scripting language like LUA into the system so that new rules can be changed/introduced without a developer, just through the admin panel. Please contact me, and we will analyze the project in detail, develop a quality technical specification, and start the development.
