Dr. Ashutosh K.

I’m a Senior Python & AI Engineer with 13+ years of production software engineering experience, specializing in Python backend systems, AI/LLM applications, automation, and scalable cloud-native platforms. Over the years, I’ve worked with 80+ clients worldwide, helping companies turn complex requirements into reliable, maintainable production systems—not just prototypes. My focus today is at the intersection of **Python, backend engineering, and AI**. ### What I specialize in **Python & Backend Engineering** * Python, FastAPI, Django, Flask * REST APIs and asynchronous services * Microservices and event-driven architectures * SQLAlchemy, Pydantic and modern Python tooling * PostgreSQL, MySQL, MongoDB, Redis and Elasticsearch * Production-ready architecture, testing and performance optimization **AI / LLM Engineering** * LLM-powered applications and AI assistants * RAG systems and enterprise knowledge platforms * Hybrid retrieval, reranking and document processing * Multi-agent systems and agentic workflows * LangGraph / LangChain-based orchestration * AI evaluation and quality/accuracy testing * Tool calling and MCP-based integrations * Structured outputs and reliable AI workflows * Self-hosted and open-weight LLM deployments * vLLM and Ollama **AI + Production Systems** I specialize in taking AI systems beyond demos and making them reliable enough for real users and production environments. This includes: * Multi-agent orchestration * Human-in-the-loop workflows * RAG over large document collections * Multi-tenant AI systems * Model/provider abstraction * Evaluation pipelines * Observability and monitoring * Security and access control * Cost and latency optimization **Cloud & Infrastructure** * AWS: EC2, Lambda, Elastic Beanstalk and related services * Docker and containerized deployments * Terraform and infrastructure automation * Cloud-native and on-premise architectures * Self-hosted AI infrastructure **Data & Automation** * pandas and Python data processing * Business process automation * ETL/data pipelines * API integrations * Workflow automation * Database optimization * Large-scale document processing ### Recent Production Experience I’ve worked on production systems involving: **Multi-Agent AI Security Platform** Built a LangGraph-orchestrated multi-agent security platform for automated penetration-testing workflows, with human approval required for destructive actions. **Enterprise RAG Platform** Designed a multi-tenant knowledge platform capable of working across millions of documents with tenant isolation, hybrid retrieval, reranking, and an evaluation framework for validating changes before production. **Backend & Automation Systems** Designed Python/FastAPI services, automation workflows, APIs and data-processing systems that reduced manual work, improved processing efficiency and enabled teams to scale their operations. ### How I Work I don’t just write code based on tickets. I can work with you from **requirements → architecture → implementation → testing → deployment → production support**. I’m comfortable working directly with founders, engineering leaders, product teams and clients, translating business requirements into technical solutions and explaining complex engineering decisions in clear language. ### Why Work With Me? You get a combination of: **13+ years of software engineering + modern Python + production AI/LLM experience + cloud/backend architecture + client communication.** Whether you need a traditional Python backend, a FastAPI/Django service, an automation platform, an enterprise RAG system, or a production-ready AI/agentic application, I can help take it from an idea to a system that your team can actually operate and maintain. I’m particularly interested in **long-term engineering partnerships** where I can take ownership of systems and continuously improve them rather than simply completing one-off tasks. Let’s build something reliable, scalable and production-ready.
