Still manually moving data between your CRM, Google Sheets, Airtable, Notion, HubSpot, Pipedrive, or some collection of tools that seemed like a good idea six months ago? At some point every growing business accidentally hires a full time employee called Copy and Paste. A lead comes in. | Someone updates the CRM. | Someone updates the spreadsheet. | Someone sends the email. | Someone books the meeting. | Then an automation breaks, and someone loses an afternoon fixing it. Most businesses do not have a people problem. They have a workflow problem. That is where I come in. I am a Top Rated AI Integration Expert and Full Stack AI Engineer with 50 completed Upwork projects, a 100% Job Success Score, Microsoft Certified AI Engineer (AI-102), and certified n8n Expert. Want proof before you spend anything? Send me a message or an invite with the tools in your stack and where it hurts. Within 24 hours I will send you a free personalized Loom audit with the two or three fastest automation wins I can see. No pitch, no obligation. If the ideas are useful, we talk. If not, you keep the ideas. I help startups, agencies, and SaaS companies build AI powered products, automate business operations, integrate CRMs, and ship production ready backend systems. Recent builds include a WhatsApp AI agent that answers travel inquiries and books trips 24/7, salon operations automation on n8n, an AI property damage assessment pipeline, and automated price monitoring with Zapier and Browse.ai. Your team gets back to thinking, deciding, and selling. Anything except updating the same CRM record for the fifth time.

I usually start there, because the hard part is not connecting tools. It is making sure they keep working next month, and after somebody changes a field name at 2 AM and forgets to tell anyone. I am a full stack engineer first, so your automations come with error handling, retries, logging, and documentation. • Backend Development and Full Stack Development • AI SaaS Development • API Integration, Webhook Integration, Third Party Integrations • NestJS, Express.js, Node.js, FastAPI • PostgreSQL, MongoDB, Supabase • MERN and PERN Stack • Golang, Docker, GitHub, AWS, Microservices Systems I have built have automated thousands of repetitive operations, streamlined lead processing, reduced operational workload, and cut customer response times from hours to minutes. A recent client put it better than I can: "I highly recommend Satyam. He cares about the quality of his work and delivered everything and more. I will hire again." I work with startups, agencies, and SaaS companies across the US, UK, Europe, Australia, and the Middle East. Available across EST, CST, PST, GMT, and other overlapping time zones, and I usually reply within a few hours. Flexible with project based work, ongoing engagements, part time support, and long term contracts. So if you are spending your weekdays, or worse, your weekends, manually updating CRMs, moving data between tools, fixing broken automations, chasing leads, or wondering why your fully automated system needs three people to keep it alive... Then it is time we had a little chit-chat. Message me, and your free Loom audit is on its way.

Still paying for tools that don't talk to each other? I build n8n automation workflows and API integrations that fix that — cleanly, on infrastructure you own and control. No vendor lock-in, no recurring SaaS fees you can't escape. Most automation freelancers hand you a Zapier flow and disappear. I deploy self-hosted n8n on your VPS or cloud (Docker, Linux), wire it to your existing stack via REST APIs and webhooks, and leave you with code and infrastructure you fully own. That means no subscription surprises and no single point of failure you can't debug yourself. What I build for SMBs and SaaS startups: 🔗 API & webhook integrations between any two platforms ⚙️ Automated workflows that replace manual ops work 🖥️ Self-hosted n8n setups on VPS or cloud (Docker, Linux) 🤖 AI agents and RAG chatbots connected to your live data 📊 CRM, lead gen, and data pipeline automations 🔍 Web scraping and data enrichment pipelines ✅ 100% Job Success Score across 28 completed projects on Upwork ✅ Top Rated freelancer — $57K+ earned, 11 active client engagements ✅ Clients include SaaS startups and SMBs across e-commerce, logistics, real estate, and recruitment ✅ Notion Service Specialist certified Send me a message describing what you're trying to automate. I'll reply within a few hours with a clear scope and whether I'm the right fit.

Overview: You have an AI product idea — or an existing product that needs AI built into its core. You need someone who won't just write code, but make the hard architectural decisions that determine whether your product scales or breaks at 10,000 users. That's what I do. I've shipped 5 AI-native products in the last 2 years, each running in production with real users today. Not prototypes. Not demos. Production systems handling real data, real money, and real compliance requirements. Recent results: → Built an AI conversation intelligence platform that analyzes calls across 19 dimensions in real-time — now processing hundreds of conversations daily for a US-based SaaS company → Delivered an AI medical education platform with 11 LLM-powered endpoints, integrating clinical evidence from randomized controlled trials — used by healthcare professionals for continuing education → Shipped an AI learning platform with 9 specialized AI pipelines — 500+ study hours saved for users within months of launch → Architected an AI-powered industrial support system with vector search and multi-tenant isolation — deployed across operator, technician, and admin roles for a European client What makes me different from other AI developers: Most developers bolt AI onto existing products as a feature. I architect systems where AI is a core capability — from database schema to user experience. Every project I deliver includes production infrastructure (CI/CD, monitoring, error tracking), not just application code. I also run a team at Growth Loops Technology, which means I can scale up when your project needs it — without you managing multiple freelancers. I'm the right fit if you need: → An AI-native product built end-to-end (backend, AI pipelines, deployment) → LLM integration done properly (structured output, RAG, multi-stage pipelines) → A senior architect who can own technical decisions and communicate clearly → Someone who ships on schedule and writes code that holds up in production Technical depth (for the engineers reading this): Backend: NestJS, Node.js, TypeScript, Python, FastAPI, Django AI/ML: GPT-4o, Claude, LangChain, LangSmith, Whisper, AssemblyAI Data: PostgreSQL, Redis, BullMQ, Pinecone, OpenSearch, Meilisearch Infra: Docker, GitHub Actions, AWS, Cloudflare R2, Sentry 15+ years of software engineering. Every project delivered with authentication, async job processing, multi-tier caching, and production monitoring baked in from day one.
