Hire the Best RazorSync Specialists

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.

Most businesses are leaking revenue because their infrastructure is held together by "digital duct tape." If your CRM is a mess, your workflows are breaking, or you’re still doing manual data entry between apps, you need a Systems Engineer. ​I build the technical engine that allows your business to run without constant human intervention. Whether it's architecting a complex GoHighLevel ecosystem from scratch or building custom full-stack applications to extend your capabilities, I ensure your technology works for you, not the other way around. ​How I can help your business: ​Engineering your GHL Ecosystem: I handle the technical "headaches" that others avoid. From A2P 10DLC compliance and custom domain mapping to complex email SMTP/API setups and Social Planner architecture. Your CRM will be a clean, high-performance environment, not a graveyard of unfinished workflows. ​Custom App & Web Development: I build high-converting funnels, corporate websites, and specialized web applications using Bolt, Replit, and Lovable. If you have a web platform that needs to live on your clients' phones, I can convert your project into a native-like mobile application. ​Advanced Automation & API Bridges: I connect the dots between your tools using Base44, Make, and custom Webhooks. I specialize in creating "Speed to Lead" systems where data flows instantly and accurately across your entire stack. Zero manual work required. ​AI Logic & Chatbots: I deploy intelligent AI agents that don’t just "chat," but actually qualify users and trigger complex backend logic, ensuring your CRM stays updated and your sales team only talks to qualified prospects. ​Scalable Tech Infrastructure: I set up the tracking, pixels, and conversion APIs needed for your paid media to scale. You get a technical foundation that is built for growth, not just for today. ​Why work with me? ​I don’t follow a "to-do" list; I analyze your business logic and identify where the friction is. I speak fluent English and understand that every line of code or automation I write must have a clear purpose: increasing your efficiency and ROI. ​I’m not here to "try" things. I’m here to build systems that work, using a professional tech stack (Supabase, Bolt, Replit, Base44) that puts you ahead of 99% of your competitors who are still stuck using basic templates. ​Technical Capabilities & Tools: ​CRM Engineering: GoHighLevel (A-Z technical setup, Snapshots, Pipelines). ​Development: Bolt.new, Replit (hosting & custom scripts), Lovable (Web-to-Mobile conversion). ​Data & APIs: Base44, Make, Zapier, Webhooks, API Integrations. ​Infrastructure: A2P 10DLC, Domain Management, SMTP/API Email logic. ​What we can achieve together: ​Transform your manual sales process into an autonomous revenue engine. ​Eliminate data silos by building custom API bridges between your platforms. ​Launch high-performance web apps and mobile-accessible tools for your clients. ​Ensure 100% data integrity and real-time tracking across your entire funnel. ​If you are ready to move away from "manual hustle" and want your systems built to professional engineering standards, let's talk.
