You will get Backend Developer | Django, DRF & Flask Expert for Scalable APIs

Project details
As a freelance backend developer, I specialize in building robust, secure, and scalable server-side applications using Django and Flask—two of the most powerful Python web frameworks. I offer end-to-end backend development solutions tailored to client needs, including RESTful API development, database modeling, user authentication, third-party integrations, and deployment.
Whether it's a startup MVP or an enterprise-grade platform, I design systems that are modular, efficient, and easy to maintain. My services also include API documentation, automated testing, performance optimization, and post-deployment support.
Project Summary:
Frameworks Used: Django, Flask
Key Offerings:
RESTful API & backend logic development
Authentication (JWT, OAuth2, etc.)
PostgreSQL, MySQL, MongoDB integration
Admin panel and dashboard creation
Integration with frontend (React, Angular, etc.)
Deployment to AWS, Heroku, or Docker-based platforms
Tools & Technologies: Celery, Redis, Django Rest Framework (DRF), SQLAlchemy, Flask-RESTful, Git, Postman

About Ishant
AI & Machine Learning | Artificial Intelligence, Information Analysis
Bilaspur, India - 8:57 am local time
My experience includes advanced data processing, cleaning, and preparation workflows, enabling accurate, reliable, and structured outcomes from complex datasets. I specialize in transforming raw data into meaningful insights and actionable intelligence using modern analytical strategies, statistical modeling, and algorithmic design.
I work extensively in the GenAI ecosystem, including RAG-based systems, vector databases, LLM-powered reasoning pipelines, voice agents, TTS engines, and retrieval-based knowledge systems. I build agentic architectures using LLM tools, structured prompting, multi-step reasoning, and external tool calling. My work spans across voice-enabled applications, automation workflows, conversational systems, and intelligent assistants.
I have strong hands-on experience developing AI automation workflows using n8n, Make.com, and Zapier, integrating APIs, message parsers, CRM systems, databases, and document pipelines. I create systems that automate data ingestion, classification, extraction, mapping, OCR processing, and AI-driven decision-making.
With strong command of Python, backend engineering, ML lifecycle management, cloud deployment, and model optimization, I ensure every AI solution I deliver is production-ready, scalable, and aligned with real business requirements. I design cloud-based and on-premise architectures combining LLMs, embeddings, vector search, and enterprise data orchestration.
My goal is to build high-impact AI systems leveraging GenAI, automation, machine learning, computer vision, retrieval pipelines, TTS/ASR, and intelligent agents. I focus on creating solutions that can think, speak, act, and automate in real time.
