I help founders, startups, and growing businesses build reliable AI-enabled SaaS products, automation workflows, CRMs, marketplaces, and custom business platforms. I’m Shivam, a Top Rated senior software engineer and technical lead with 16+ years of experience, $200K+ earned on Upwork, and 18,000+ hours delivered across production software projects. My strength is not just writing code. I understand product flow, backend logic, data movement, user roles, integrations, edge cases, and the business process behind the software. That matters because most AI and SaaS projects fail for practical reasons: unclear workflows, weak architecture, poor data handling, unreliable integrations, or features that work in demo but break in real use. I can help with: - AI workflow automation using OpenAI, Claude, GPT, n8n, Make, and custom APIs - Python and FastAPI backend development - React dashboards, portals, admin panels, and internal tools - SaaS MVP development from idea to production - CRM, marketplace, and business workflow platforms - API integrations, database design, and backend architecture - Existing product improvement, rescue, modernization, and performance fixes - RAG systems, AI assistants, document workflows, and AI-enabled reporting I have worked across Python, Node.js, React, PHP, Ruby on Rails, databases, APIs, and cloud-based systems. I’m comfortable joining early-stage product discussions, reviewing architecture, clarifying scope, and then building the right technical foundation. Clients usually work with me when they need someone who can think beyond tickets, communicate clearly, and take ownership of the technical direction. A few relevant areas I can support: - AI lead qualification and follow-up automation - AI assistants connected to business data - SaaS MVPs with secure backend and clean frontend - CRM and workflow automation - API-heavy dashboards and internal tools - Legacy system modernization - Complex backend logic and scalable architecture My approach is simple: understand the business problem first, design the right technical flow, then build something practical, maintainable, and useful in the real world.

I build backend systems and AI pipelines. My main work has been on production LLM systems, including a RAG pipeline that grounds AI responses in real data and eliminates hallucinations. I built a conversational AI platform's backend from the ground up. Python and FastAPI, async architecture, vector database integration, and prompt caching to manage API costs and latency. I migrated the infrastructure to containerized services with auto-scaling, rewrote the storage layer to cut costs significantly, and scaled the system from a small user base to thousands of active users. I have also designed RBAC modules for multi-tenant security dashboards, containerized legacy .NET services, and worked across both Azure and GCP environments. Right now, I am building a distributed key-value store in Go with Raft consensus, deployed across a multi-region Kubernetes cluster on three continents.
