Fixed-Price Python Development

REST & GraphQL APIs

Well-structured APIs with proper validation, authentication, and documentation. We build endpoints that are consistent, well-tested, and easy for your frontend team to consume. Every API comes with auto-generated OpenAPI docs, proper HTTP status codes, and clear error messages that help developers debug issues quickly.

Database Design

Schema design, migrations, and query optimization for PostgreSQL, MySQL, and more. We design normalized schemas with proper indexes, constraints, and relationships from the start — including foreign keys, check constraints, and sensible defaults that prevent bad data from entering your system. When your database grows, we optimize slow queries and restructure tables without downtime.

Task Automation

Automate repetitive processes with Python scripts, cron jobs, and workflows. From data imports and report generation to invoice processing and email campaigns, we build automation that runs reliably and handles errors gracefully without human intervention. Every automation includes logging, alerting for failures, and documentation so your team understands what runs and when.

Data Processing

ETL pipelines, data transformations, and integration with data stores. Whether you are pulling data from third-party APIs, cleaning CSV uploads, or building analytics pipelines, we create robust data processing systems that handle edge cases, validate inputs, and scale with your data volume. Pipelines include monitoring for data quality issues and alerts when source data changes unexpectedly.

Authentication & Security

JWT, OAuth, role-based access control, and security best practices. We implement authentication systems that are secure by default — proper password hashing with bcrypt, short-lived access tokens with refresh token rotation, granular permission hierarchies, and protection against common attacks like SQL injection, CSRF, and brute-force login attempts.

Testing & CI/CD

Pytest test suites, code coverage, and continuous integration setup. We write tests that verify business logic, not just code paths — covering happy paths, edge cases, and error conditions. Every feature comes with integration tests that run against a real database, and we set up CI pipelines so your team catches regressions before they reach production.
