Dhaneshwar Kumar Singh
I help startups, founders, and engineering teams build, scale, and ship production software. With 10+ years of comprehensive experience, I specialize in full-stack web platforms, containerized microservices on AWS, and autonomous AI systems.
I am also the creator of Learning Master — a platform dedicated to high-signal software engineering tutorials, architectural blueprints, and real-world developer tools.
Senior-Level Engineering Without the Agency Overhead
Direct collaboration with a 10+ year veteran who writes the code, designs the architecture, and handles deployments.
End-to-End Full-Stack Execution (0 to 1)
From database modeling in PostgreSQL/MySQL to Python (Django/FastAPI) backends and modern React.js/Node.js responsive user interfaces — delivered cleanly without technical debt.
Cloud-Native AWS & Docker Microservices
Battle-tested infrastructure blueprints: AWS ECS Fargate, Lambda serverless, S3, RDS Multi-AZ, and GitHub Actions CI/CD pipelines for automated zero-downtime releases.
Production AI & Agent Workflows
Building reliable AI workflows using LangChain, LangGraph state machines, ChromaDB/pgvector vector stores, and OpenAI/Claude tool-calling to automate real business operations.
High Performance & Scalability
Eliminate database locks and slow queries. Specialized in SQL query optimization, Redis in-memory caching, async FastAPI handlers, and high-concurrency architectures.
