Python, Django & FastAPI

Build fast, secure, and scalable web backends with TAS. Our Python developers specialize in Django and FastAPI to deliver modern APIs, admin systems, and ML-powered platforms. Trusted for fintech, healthtech, AI tools, and enterprise backend development.

Secure, scalable APIs and web applications powered by Python โ€” built for startups, enterprises, and AI-driven systems.


๐Ÿ” Python at the Core of Modern Backend Development

Python is no longer just for data science โ€” it powers some of the most secure and scalable backend systems in fintech, healthtech, AI platforms, and global SaaS products. At TAS, we bring over a decade of backend engineering experience using Python and its top web frameworks โ€” Django and FastAPI โ€” to build reliable, high-performance server-side architectures that are easy to maintain and evolve.

From secure admin portals and multi-user CMS platforms to blazing-fast APIs that power mobile apps or AI workflows, our Python backends are engineered for both performance and long-term scale. Whether you’re looking to build an internal tool, customer-facing application, or a data-heavy backend system, we help you get there with clean, modular, and well-tested code.


โš™๏ธ Why Django and FastAPI?

Django is a robust full-stack web framework trusted by developers and enterprises for its speed, security, and โ€œbatteries-includedโ€ philosophy. Itโ€™s perfect for projects where rapid development, admin interfaces, and scalability are a must. On the other hand, FastAPI is our go-to framework for building asynchronous, blazing-fast APIs with automatic documentation (OpenAPI/Swagger), perfect for modern microservices and AI-first platforms.

Depending on your productโ€™s goals, we leverage the best of both โ€” Django for structured web apps with ORM and built-in admin tools, and FastAPI for async endpoints that interact with ML models, real-time data, or mobile clients.

๐Ÿš€ Portfolio Highlights with Python, Django & FastAPI

๐Ÿฉบ Mariana AI โ€“ Multilingual Medical Transcription & EHR Automation

We developed the backend system for a multilingual AI-powered platform used by doctors to record and retrieve patient notes via voice. Using FastAPI, we orchestrated audio uploads, language detection, Whisper + GPT-powered transcription, and medical summary generation. The backend included role-based access, audit logs, and secure storage.


๐Ÿ“„ Gram Vaani โ€“ Voice Analysis System for Rural Call Centers

We built a backend pipeline that receives voice calls from rural users and processes them using speech-to-text, translation, and LLMs. Using Python microservices with FastAPI, the system transcribes local language queries, generates AI-based responses, and converts them back to voice. Django-based admin panel supports monitoring, escalation, and moderation workflows.


๐ŸŒย Internal Blockchain Config Dashboard for Mai Labs

Created a Django-based internal tool for Kalp Layer 1 blockchain team to manage token configurations, validator settings, exchange rules, and more. Included login management, user roles, and internal audit trails.


๐Ÿง  Built for AI, Automation & Scale

Our Python backends donโ€™t just serve static data โ€” they orchestrate AI workflows, trigger real-time automation, and handle large volumes of user interactions. From integrating OpenAI / LangChain pipelines to generating voice-to-text medical records, we combine backend engineering with smart automation to deliver intelligent platforms that work seamlessly at scale.
