Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store. I build and fix the middleware/API layer behind those systems. My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned. What I usually handle: - Shopify / Shopify Plus integrations and custom commerce workflows - ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems - POS and inventory workflows: Clover, store operations, loyalty, order flows - Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs - Admin dashboards, reporting panels, and operational data models - Production debugging where the issue is hidden across multiple systems Relevant background: - Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations - Led technical delivery across teams of 20+ - Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and payment systems I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability. If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.

⚡ Built a $20K+ ticket AI lead-management system for a wildlife adventure business — captures, qualifies, books, and follows up with every inbound lead automatically across CRM, automation, and email. ⚡ Built an autonomous AI developer for an ERP integrator — 11 Claude agents that read a user story out of Odoo, audit whether it's ready, write the code, open the GitHub pull request, and post the status back into the ERP. Custom Python MCP server, so no agent ever holds client credentials. Live in production. ⚡ M.Sc. Signal Processing + 8 yrs engineering — real systems rigor (error handling, monitoring, integrations that don't break at 2 AM), not a no-code generalist. I build AI agents and CRM automation that run in production, not in a demo video. GoHighLevel, Pipedrive, n8n, Make, Python, Claude & OpenAI — whatever the job needs. What I build: • AI agents that capture, qualify, and follow up with leads across email, chat, and SMS • Agentic systems wired into your real tools — ERP, CRM, ticketing, GitHub — with credentials isolated behind an MCP server • GoHighLevel (GHL) — sub-accounts, pipelines, calendars, automations, snapshots, A2P/SMS, white-label • CRM automation & integrations — sync leads, contacts, deals across GHL, Pipedrive, HubSpot, and your stack • RAG / AI search over your document catalog — ingestion, embeddings, citation-backed answers • Lead-gen & nurture pipelines — intake → scoring → routing → automated follow-up • Document processing — extract, classify, push data into your CRM • Reporting dashboards pulling every source into one view How I keep agents safe in production: readiness gates before an agent acts, human-approved drafts for anything customer-facing, confidence thresholds that route to a person instead of guessing, and monitoring you can actually read. My approach: start with your sales/ops process, find the highest-ROI automation, ship a working prototype fast, then iterate. No bloated proposals — just results. Tech: Claude API, OpenAI API, MCP, GoHighLevel, Pipedrive, n8n, Make, Python, FastAPI, Supabase, PostgreSQL, vector databases, REST APIs, webhooks, Telegram/SMS, email automation. Background: M.Sc. Signal Processing, 8 years engineering (embedded systems, FPGA, industrial controls). Engineering rigor in automation — proper error handling, monitoring, systems that don't break at 2 AM.

HI! I’ve built 40+ AI agents and automation systems handling thousands of tasks daily from lead processing to full operational workflows. Most clients come with something that “almost works”. Flows break. Data is messy. No one understands what happens inside. I fix that. I design automation with clear logic, clean data flow, and control at every step. If something fails it retries. If data is wrong — it is blocked. If system grows — it still works. What I usually build: – AI agents for operations and sales – n8n / Make workflows with real error handling – CRM and API integrations – data pipelines and internal toolsWhat I build: – Supabase and PostgreSQL backends with clear schema – Internal tools with lovable and supabase – Data pipelines from scraping to AI to CRM I use AI to move faster. But I always check logic and edge cases manually. Experience: 40+ AI agents and automation systems RAG systems with vector search and clean outputs CRM and sales automation pipelines internal tools with supabase and APIs systems built for real load If your automation is messy I can rebuild it. If you start from zero I can design it right. 🔧 Stack: n8n | make | supabase | postgresql | lovable | openai | rag | apis | webhooks | crm systems | data pipelines | ai agents

I'm Rajat, a 6× Salesforce-certified developer and consultant with 6+ years of hands-on experience across most major Salesforce clouds and capabilities. Whether you need a quick Flow fix, a complex Apex build, a full implementation from scratch, or to pick up a stalled project, I've likely worked on a version of it before. I work across the platform rather than specializing in one area. From Sales Cloud to Service Cloud, Marketing Cloud to Field Service, Revenue to Mulesoft integrations, it's all one platform to me, and I try to treat it that way.

I automate operations for founders. Custom dashboards, AI voice agents, and automations built into your business and existing tools, designed around how your team actually works and shipped fast. 𝗥𝗲𝗰𝗲𝗻𝘁 𝘄𝗼𝗿𝗸: → Built inbound and outbound AI voice agents that handle calls, qualify leads, and book appointments without a human touching the phone. Live and running for real operations. → Built custom AI assistants and chatbots connected directly to databases, pulling live data to answer questions and return dynamic, real-time results instead of canned responses. → Built full GoHighLevel automation from lead intake to closure, powered by an AI SMS SDR that replies instantly, follows up on its own, and flags leads for human review when they need a real person. The system sorts hot and cold leads automatically and delivers daily insights across the whole pipeline. Running across healthcare, real estate, HVAC, and law firm operations. → Analytics system tracking $2.4M in revenue in a single month for a high-ticket sales operation; $4.6M all-time. Leadership watched $1.4M close in one week from a single screen; rep performance, pipeline stages, conversion rates, all live. → Upgraded a real-estate operation from manual Excel sheets to a custom dashboard powering automations across their pipeline without manual work. Claude plugged into the same data, answering business questions, flagging bottlenecks, and surfacing daily reporting improvements. → Worked with SaaS product owners building their MVPs from prototype to production, then scaling them. Multi-client Stripe billing for clean onboarding, RAG systems making AI features actually deliver, and the production engineering to ship something real. → A founder running a live AI product had watched his in-house dev team struggle for three months to get the AI behaving the way he wanted. Came in, worked the problem from first principles, got it shipping the experience he envisioned. Live with real users. I also help founders figure out what to build and where things break, and consult on their more novel problems: new AI use cases, LLM behaviour, agent architecture, voice agent design, making your vision come to life. Claude Code is my daily infrastructure. Multiple businesses run their day-to-day on what I've built; ops, SaaS, LLM products, voice agents, all in production. If you've got something to build or fix, let's talk.

Every missed call is a lost customer. I build production-ready AI Voice Agents that answer, qualify, and book calls 24/7 — so your business never loses another lead to a busy line or an after-hours voicemail. I'm a Top Rated Upwork specialist (100% Job Success, 61 completed projects, 1,800+ hours) focused exclusively on one thing: AI phone agents that sound human, integrate with your existing systems, and actually convert. What I build: ● AI Receptionists that answer every call, in seconds, 24/7 ● AI Appointment Booking Agents synced to Google Calendar and your CRM ● AI SDRs and Outbound Calling Agents for lead qualification and follow-up ● Customer Support Voice Agents for FAQs, order status, and call routing ● HIPAA-aware Medical and Dental AI Receptionists ● Real Estate AI Voice Agents for lead capture and showing scheduling ● Restaurant Ordering and Reservation Agents Tech stack: Vapi, Retell AI, Twilio, ElevenLabs, Deepgram, OpenAI, Claude, n8n, Make, GoHighLevel, HubSpot, Google Calendar, Airtable, REST APIs & Webhooks Why clients hire me: Most voice AI freelancers specialize in a single platform. I build on both Vapi (for fully custom logic and integrations) and Retell AI (for the lowest-latency, most natural-sounding inbound experience) — so I recommend the right stack for your call volume and use case instead of forcing every client onto the same tool. Every agent I ship is tested against real-world conditions — interruptions, background noise, accents, and edge-case questions — not just a clean demo script. If missed calls, slow lead response, or an overwhelmed front desk are costing you business, message me. I'll walk through your current call flow and show you exactly what an AI Voice Agent would handle for you.
