Most businesses are leaving money on the table, not because they lack a great service, but because their systems, marketing, and follow-up aren't working together. That's exactly what I fix. I'm a GoHighLevel expert specializing in building the full growth infrastructure behind a business, from the first touchpoint with a lead all the way to repeat purchases, referrals, and long-term client retention. I've worked with startups and growing businesses, helping them to increase ROI by putting the right systems in place and letting automation do the heavy lifting. My strength lies in understanding your actual business goals and translating them into practical, measurable marketing solutions. I focus on long-term partnerships, clear communication, and outcomes that show up in your revenue, not just your reports. I audit where your business is bleeding leads and revenue, close those gaps, and build out a fully automated ecosystem so your business runs, nurtures, converts, and retains clients even when you're not in the room. ✅ Full GoHighLevel setup and optimization ✅ Sales funnels and high-converting websites from scratch ✅ Lead generation and lead nurturing systems ✅ Automated follow-up sequences that turn cold leads into paying clients ✅ Email and SMS marketing campaigns ✅ Client lifecycle management and re-engagement automation ✅ Loyalty, rewards, and retention systems ✅ Reviews and reputation management automation ✅ Marketing strategy built around your actual numbers and goals The result? Your business generates more leads, converts them faster, keeps clients longer, and grows revenue through repeat business, on autopilot. If you're looking for a reliable marketing partner who values performance, transparency, and growth and is tired of piecing together tools that don't talk to each other, let's talk.

I am a full-stack healthcare and technology engineer with 14+ years of experience delivering compliant, scalable, and intelligent systems across Healthcare, FinTech, Web3, AI Automation, Mobile, and Gaming. My primary focus is healthcare, building platforms that meet the most rigorous compliance standards while integrating seamlessly into real-world clinical ecosystems. Healthcare Engineering & Compliance I specialize in HIPAA, FHIR R4, HL7, GDPR, PIPEDA, and SOC2-compliant product development, with hands-on integration experience across Epic, Oracle Cerner, Meditech, and Athenahealth. I design and build telemedicine platforms, EHR/EMR systems, patient portals, remote patient monitoring (RPM) tools, AI clinical assistants, medical imaging platforms, ePrescription and pharmacy integrations, IoT wearable connectivity, lab & diagnostic APIs, and enterprise healthcare SaaS. Every system I deliver includes secure PHI handling, audit logging, encryption standards, and role-based access controls. Key deployments: 1. Huma (global digital health, 70+ countries, 100M+ patients). 2. GoToDoctor (full telehealth ecosystem) 3. Biocalculus (AI cardiac monitoring with Bluetooth ECG streaming, cloud backend, and deep learning arrhythmia detection). AI Bots & Intelligent Workflow Automation I build NLP-driven, role-aware AI workflow agents that sit as an intelligent overlay on top of your existing application, reducing per-role workload without requiring a full platform rebuild. This approach is cost-efficient, non-disruptive, and has been deployed across both Web2 healthcare systems and Web3 decentralized environments. I integrate LLMs, build custom AI Workflow agents, and architect automation pipelines that scale with your team. FinTech, Web3 & Blockchain My FinTech experience covers crypto and stock trading platforms, investment dashboards, and DeFi tooling on Ethereum & Solana. I've built Web3 automation bots, smart contracts, and hybrid Web2/Web3 architectures, applying the same compliance and engineering rigor from healthcare into high-stakes financial systems. Mobile Development I am currently developing Kotlin/React Native/Flutter-based Android applications with a focus on healthcare, including real-time device streaming(wearable data), secure cloud data pipelines, and clinical-grade UI/UX. My mobile work spans patient-facing apps, clinician tools, and IoT device companions. Gaming & Creative Tools I've delivered high-concurrency systems for Asia's top-listed gaming companies and also built Canvas-based image editor/creator tools in the Web2 space, demonstrating range across demanding, performance-critical environments. White-Label Enterprise CRM, POS, ERP & Inventory I offer a pre-built, enterprise-grade white-label platform covering CRM, Point of Sale, Inventory Management, and ERP ready to launch under your brand. This saves months of development time and significantly reduces go-to-market cost for businesses needing a complete operational platform.

I build AI agents, voice pipelines, and n8n/GHL automations that replace manual workflows in production - not prototypes, not demos. What I have delivered recently: 1. Claude-powered intake agent replacing a manual lead qualification process for a SaaS team 2.

Multi-step LLM workflow extracting structured data from unstructured documents with 25+ field accuracy 5. Full-stack Laravel + AI SaaS built from spec to deployed in under 8 weeks I also bring 12 years of full-stack development experience (Laravel, React, Node.js, PHP, Python) - so if your project needs AI features built into an existing app, or a new SaaS product from scratch, I can handle both the AI layer and the underlying system. Tools & stack: Claude , OpenAI, ElevenLabs, Vapi, Retell, n8n, Makecom, GoHighLevel, Laravel, React, Vue, Node.js, Python, REST APIs, Stripe, Razorpay, AWS, Docker. I scope accurately, communicate clearly, and build fast. If your project involves replacing a manual process with AI that runs in production, or needs full-stack development with AI integration, I have probably already built something close to what you need.
