PostgreSQL REST API Development

@chesslover

Hello there, I'm Valentino, a Senior Software Engineer and a specialist with FastAPI, Postgres, and RESTful API development including Hypermedia REST (HATEOAS) and Reactive REST. The database schema will be designed with the usual best practices such as normalization, indexes, and more. FastAPI SQLModel will take care of the ORM abstraction. FastAPI also includes Swagger documentation. I will also include the database migration with seed data. I'm also a solar energy enthusiast and a board-certified Electronics Engineer. I have hand-built my own 25-kWh (25,000 watt-hours) LiFePO4 solar UPS backup system for my home consisting of three solar inverter banks. LiFePO4 battery systems are my specialty. I'm a Will Prowse disciple and I have over 500 posts in his solar energy community. Thank you, Valentino

1189 characters, 199 words, within limits. No em-dashes, no greeting, no signoff, two closing questions. Solar TwinPro's core resource set is the kind of schema where getting the foreign keys and versioning right up front saves the frontend team weeks of guessing later. I'd build this OpenAPI-first: define the /v1 contract before writing a single CRUD handler, so the Swagger spec that ships with the API is the actual source of truth, not a doc generated after the fact and quietly out of sync. Schema design and seed data come first, migrations included so the dataset is reproducible on a clean container. Then full versioned CRUD across the core resources, proper status codes and pagination, nothing half wired. Docker packaging wraps it so your frontend team can clone, run one compose command, and hit sample requests against a live spec without needing anything from me. M1: schema design, migrations, seed data, 10519 INR, 1.5 days. M2: versioned CRUD across all core resources, 12750 INR, 2 days. M3: OpenAPI/Swagger spec plus Docker packaging and a smoke-tested compose file, 8606 INR, 1.5 days. Are the core resources locked already or still being scoped, and does the frontend team have a preferred auth scheme, JWT or session-based, so I match it in the spec from the start?

Hello Sir, I am from Banglore. Clean, versioned API work — the design decision that matters most is getting the schema right upfront, since every CRUD endpoint and the OpenAPI spec both depend on it. My approach: design the PostgreSQL schema first with proper relationships and constraints, then expose versioned REST endpoints (/api/v1/...) with consistent JSON response shapes and standard HTTP status codes throughout — 201 on create, 404 on missing resources, 422 with structured field errors on validation failures, so the front-end team never has to guess. FastAPI generates OpenAPI/Swagger docs automatically from the code, so documentation stays accurate as endpoints evolve rather than drifting from a hand-maintained spec. Delivered as a Dockerised project with a docker-compose setup (API + Postgres), seed data, and run instructions — spin up and test locally in one command. Question: do you have an entity list/data model already, or should that be part of this scope? I have worked here with more than 130+ clients. Available immediately. Best regards, Vishruth

@sarimshoaib1425

100% doable. PostgreSQL + REST API build, right in my range. Built backend systems with API/webhook integrations and database work for automation clients before, so designing a clean CRUD API with proper schema is straightforward. I'll design the PostgreSQL schema and seed data, build versioned REST endpoints covering full CRUD for each resource with consistent status codes and error handling, containerize it with Docker for easy deployment, and generate an OpenAPI/Swagger spec so your front-end team can plug in without back-and-forth. Feel free to DM me for case studies. Or check the projects on my profile. Let's do it.

Hi, I can build a clean PostgreSQL-backed REST API for your Solar TwinPro web application, including schema design, seed data, versioned CRUD endpoints, Docker setup, and OpenAPI/Swagger documentation. The best solution is to first review the core entities, relationships, frontend data requirements, authentication needs, and deployment target. Then I’ll design a normalized PostgreSQL schema, prepare DDL and seed data, and build consistent JSON REST endpoints with proper status codes, validation, error handling, and maintainable project structure. I’m comfortable with PostgreSQL, REST API development, database schema design, JSON APIs, Docker, OpenAPI/Swagger, CRUD endpoints, seed data, API documentation, environment configuration, and frontend-backend integration workflows. Deliverables will include: * PostgreSQL schema and DDL * Seed data * Versioned REST API endpoints * Full CRUD for defined resources * JSON response structure * Validation and error handling * Dockerfile/setup script * Environment/run instructions * OpenAPI/Swagger documentation * Local testing support I’ll focus on building a reliable, well-documented API that your frontend team can connect to easily and that runs locally without setup confusion.

@richard031596

You need a PostgreSQL-backed REST API for Solar TwinPro with a clean database structure, reliable CRUD endpoints, and documentation that allows the frontend team to integrate without confusion. I can design the schema, build the API layer, containerize the service, and provide clear setup instructions. I have experience building backend APIs with Python frameworks such as Django and FastAPI, working with PostgreSQL databases, Docker deployments, JSON-based integrations, and API documentation workflows. I focus on creating maintainable endpoint structures with proper validation, error handling, and versioning. Would you like the API built with a specific backend framework, or should I recommend the best approach based on your frontend requirements?
