Most engineers can write code. Fewer can take a vague product idea, architect it properly, and ship something that holds up in production six months later without it becoming someone else's problem to maintain. That's the work I do. I'm Vikram, a Senior AI and Full Stack Engineer with 6+ years of experience, $70K+ earned, and 25+ projects delivered on Upwork. I work with startups and product teams who are building things that actually need to work: AI-powered systems, scalable SaaS backends, and full stack platforms that grow with the business. If you have ever been handed code that "technically works" but nobody can explain, or an AI demo that never made it to production, you'll know exactly why architecture and delivery discipline matter. That's where I come in. AI Systems and Agent Development: - LLM integrations using OpenAI GPT-4o, Anthropic Claude, Gemini, Mistral, and Vertex AI - AI Agents and multi-agent systems using LangGraph, CrewAI, AutoGen, LlamaIndex, and Mastra - RAG pipelines with Pinecone, Weaviate, ChromaDB, and FAISS - Voice AI agents using ElevenLabs, Whisper, VAPI, and Deepgram - MCP (Model Context Protocol) integrations for tool-connected, context-aware agents - Long-term agent memory with Mem0 and Zep - AI workflow automation using n8n, Make, and Zapier - Document intelligence, semantic search, and knowledge base systems - AI-powered automation for legal, HR, sales, and enterprise workflows Backend Architecture and APIs: - Node.js and Python backends using FastAPI, Django, and Express.js - REST and GraphQL APIs built for scale and long-term maintainability - Multi-tenant SaaS architecture with authentication, RBAC, and audit logs - Payment integrations and subscription billing systems - High-performance database design using PostgreSQL, MongoDB, and MySQL Full Stack Development: - React and Next.js (TypeScript) for SaaS dashboards, admin panels, and client portals - Real-time features and API-driven frontends - Vercel AI SDK for AI-native web applications Cloud and DevOps: - AWS, GCP, and Azure deployments - Docker, CI/CD pipelines, and GitHub Actions - Scalable infrastructure with monitoring and error handling built in from day one, not bolted on after launch Industries: - AI/SaaS and Product Startups - FinTech and Payments - LegalTech and Contract Automation - HR Tech and Workforce Platforms - EdTech and Learning Platforms - Healthcare and Digital Health - Logistics and Supply Chain - Enterprise Automation and Internal Tools - E-commerce and Marketplace Platforms - Real Estate and PropTech - Marketing Tech and Growth Platforms - Cybersecurity and Compliance Tools - BI, Analytics and Data Platforms What Clients Say: "Vikramjeet was dedicated to providing timely and complete solutions. His communication was regular, he was able to meet deadlines, and he has a broad range of technical skills." "With minimum communication, he understood what we need and implemented it right away. What impressed me most was his commitment to delivering fast and his commitment to the deadline." If you are building an AI product, a scalable backend, or a full stack SaaS platform and need someone who can own the architecture end to end, tell me what you're working on.
