I have more than 12 years of experience in web and software development. Currently working as automation consultant and fullstack engineer and/or fractional CTO on-demand. For development my preferred tech stack is React, NextJS, TypeScript, NodeJS, GraphQL, Supabase, AWS all AI accelerated using Claude Code. Also love tinkering with new tools and solutions like Openclaw and agents for businesses. I am comfortable building AI applications using Claude, OpenAI APIs via AI SDK or directly via API integrations to build agentic workflow or AI agents in combination with n8n as orchestrator or standalone custom builds. For automations I mainly automate sales or marketing processes in Zapier and n8n integrated with various systems or custom APIs using JavaScript and hands-on experience integrating with Airtable, Notion, Pipedrive, Basecamp, Cal and other tools. In my previous role for 5 years, I have been working as CTO and technical founder for a e-commerce platform taking an engineering team from 0 to 70 engineers. I am comfortable as a consultant choosing the right tech stack or architecture as well as building applications hands-on myself. Creating digital solutions, websites and web applications is my passion. I can take a website from system design/architecture to prototype and into a working Headless CMS-based website or application deployed to Netlify, Vercel or AWS Amplify. Being a full-stack developer with main expertise in frontend development (HTML, CSS), NodeJS and application architecture especially using AWS and Serverless framework. Developing applications using Apollo Client, ReactJS, NextJS, GatsbyJS, NodeJS, GraphQL with Apollo Server or Hasura, AWS Lambda, DynamoDB. Since March 2016 I am Certified AWS Solution Architect and been using AWS since 2015 with heavy use of EC2, Cognito, S3, Cloudfront, RDS as well as serverless architecture (AWS API Gateway, Lambda and DynamoDB).

Hey, I am Madhu👋, I build AI automation systems that survive real users and real data, including the closed-system integrations and custom API work most freelancers won't touch. Top Rated Plus. 100% Job Success Score. 1,384 hours of AI automation delivered across 17 jobs. My biggest single contract: 633 hours building the AI sales automation and CRM backend for a B2B service business across an 11-month engagement. I work in n8n, Make (Integromat), GoHighLevel, Supabase, and Claude Code every day. If your tools won't communicate, your CRM has no public API, or your team is drowning in manual work, that is what I fix. ═══ Where I'm Different ═══ Most automation people can wire up a tutorial. Few can ship a system that runs for months without babysitting. When your CRM or vertical SaaS has no public API, I reverse-engineer the request flow with Chrome DevTools and payload analysis, then wrap it in a clean MCP server or n8n integration so your systems finally communicate. That closed-system work is what most freelancers turn down. I came to automation through running operations for B2B service businesses, so I understand the ops side as well as the code. ═══ What I Build ═══ ➤ n8n and Make Production Pipelines End-to-end workflow automation on self-hosted n8n and Make with error handling, retries, and monitoring. Not workflows that look good in a Loom. Workflows that run unattended for months. ➤ Closed-System Integrations (MCP Servers and Custom APIs) When two tools refuse to communicate, I build the bridge. I reverse-engineer closed systems with Chrome DevTools, then expose them through clean APIs or MCP servers so Claude and your stack can read, write, and orchestrate reliably. ➤ AI Agents, Claude Code, and Claude Skills Custom AI agents and reusable Claude Skills that turn AI into a domain expert for your business. SOP-driven, version-controlled, built so your team can extend them. ➤ CRM and GoHighLevel Automation GoHighLevel, HubSpot, Airtable, and Supabase pipelines built so nothing falls through the cracks. Lead scoring, routing, follow-up, and reporting wired end to end. ➤ B2B Lead Generation and Outreach Systems Apollo to Clay enrichment to Instantly and HeyReach sequences to CRM pipeline. Cold email and LinkedIn outreach that books qualified meetings on autopilot. Around 93% open rates, sometimes 98%. ➤ Data Operations and Web Scraping Large-scale scraping, enrichment, and deduplication pipelines that feed clean, segmented data into your CRM. ═══ Tech Stack ═══ Automation: n8n, Make (Integromat), Zapier. AI/LLM: Claude API, OpenAI API, Claude Code, MCP servers, HeyGen, Vapi. Lead Gen: Apollo, Clay, Instantly, HeyReach. CRM: GoHighLevel, HubSpot, Pipedrive. Data: Supabase, Airtable, Apify. Docs: PandaDoc, Jotform, DocuSign. ═══ Industries I Work With ═══ ➤ Automotive and trade: automation and CRM build-outs for ceramic coating and PPF detailing businesses. ➤ Metal fabrication: a 60+ node sync between GoHighLevel and a closed-system fabrication CRM with no public API, 14,000 leads migrated through a Supabase staging layer. ➤ Staffing and recruiting: candidate sourcing and outreach for 9 staffing firms. Cut hiring from 6 weeks to under 1 week, lifted qualified candidate rate from 40% to 78%. ➤ Insurance recruiting: automated placement funnels for remote sales roles. ➤ Ecommerce: AI-powered listing optimization and marketplace automation. ➤ HR and document automation: paperless onboarding across PandaDoc, Jotform, and DocuSign, including reverse-engineered, undocumented API endpoints. ═══ Proof ═══ ✔ 633 hours on a single B2B sales automation and CRM backend, 11-month engagement ✔ 60+ node closed-system CRM sync, 14,000 leads migrated ✔ Hiring cut from 6 weeks to under 1 week ✔ Qualified candidate rate raised from 40% to 78% ✔ Around 93% email open rates, sometimes 98% ✔ Backend supporting 9 staffing agencies and 1,000+ professionals ═══ What Clients Say ═══ ★★★★★ "Great approach for understanding the case deeply, great communicating skills, and real commitment. I truly recommend work with Madhu!" (AI eCommerce Automation, Mar 2026) ★★★★★ "This is one of the highest level freelancers and highly recommended." (HR Document Automation, Oct 2024) ═══ How I Work ═══ ✔ Free 30-minute discovery call to map the real bottleneck ✔ Written architecture proposal before any code ✔ Working build inside 2 weeks for most scopes ✔ Full documentation, SOP, and a Loom walkthrough on handover ✔ Daily Slack updates while building, no surprises ═══ Best Fit ═══ You are a good fit if you are a service, trade, staffing, or B2B business losing hours to manual work, or stuck because two systems won't communicate. Send me your messiest workflow, or the tool that refuses to connect to your CRM. I'll tell you exactly how I'd automate it and what results to expect.
