Is your AI agent a production system or a fragile demo? Most AI agent projects collapse the moment they hit real traffic. 🏆 20+ years architecting production systems at principal engineer level 📊 $100K+ earned on Upwork across 32 architecture projects 🎯 100% Job Success Score, Top Rated Plus on Upwork ⚡ Built an MCP server connecting AI agents to live financial operations on Solana 💼 CEO at Osambit, a 20-person AI agent engineering team ✅ Enterprise Blockchain Architect certified, former Sr Principal Engineer at Nordstrom ⭐⭐⭐⭐⭐ "We've had the opportunity to collaborate with the Osambit team, and it's been a great experience. They're highly professional, responsive, and truly understand the final goal. Their technical expertise and ability to deliver on time have been key to the success." (Alwyn V., IXO World) As an AI Agent Architect with 20+ years of production engineering experience, I build AI agent systems using LangGraph, LangChain, and MCP that run in production, not prototypes that die in demos. Every AI agent project I take on starts with a decision graph - what the AI agent handles autonomously, what escalates to a human, and where it fails safely. That architecture-first approach is why my AI agent systems survive real traffic while cheaper builds collapse on edge cases. 🔶 IXO World (AI agent architecture): full-time Q4 2024 engagement | delivered on time | team collaboration verified by client testimonial above 🔶 Meteora + proprietary DLMM protocol (AI agent + DeFi automation): $81K engagement | MCP server linking AI agents to live trading operations | real-time autonomous execution with human-in-the-loop safeguards 🔶 Roover.AI (AI agent system architecture): intelligent B2B2C roof estimation platform | multi-modal RAG pipeline design | production deployment 🔶 Nordstrom (Sr Principal Engineer, 5 years): architected 9+ enterprise systems | supported 10 offshore engineering teams | supply chain, payment, logistics domains WHAT I DO ✅ AI Agent Architecture: decision graph design, multi-step workflow orchestration, human-in-the-loop control for every AI agent system ✅ LangGraph & LangChain Systems: production AI agent pipelines with state management and tool connectivity ✅ MCP Server Development: Model Context Protocol servers connecting AI agents to real business systems ✅ RAG Pipelines: retrieval-augmented generation grounding LLM answers in your knowledge base ✅ Multi-Agent Orchestration: CrewAI, LlamaIndex, and custom AI agent orchestration for complex agentic AI workflows ✅ AI Agent Security Hardening: prompt injection defense, data leakage prevention, auditability ✅ LLMOps & Production Deployment: tracing, observability, evaluation frameworks, regression testing for AI agent systems ✅ OpenAI & Claude API Integration: enterprise-grade AI agent integration with cost, latency, and failure-mode management WHO I WORK WITH 🎯 B2B and B2C companies building AI agent products, not one-off assistant setups 🎯 Founders and CTOs who need AI agent systems running in production with real users 🎯 Teams with multi-week engagements (4+ weeks minimum), not 5-minute tasks 🎯 Companies that understand AI agent architecture is a design problem, not a prompt problem 🎯 Clients who value senior engineering judgment over the cheapest hourly rate MY PROCESS 1️⃣ Architecture Review: 24-hour turnaround on a decision graph, failure-mode map, and scope estimate for your AI agent project 2️⃣ Design: AI agent flow specification, tool boundaries, escalation rules, evaluation plan 3️⃣ Build: production AI agent system with observability, security, and regression tests from day one 4️⃣ Deploy & Iterate: staged rollout, LLMOps monitoring, iterative refinement of the AI agent based on real usage Send me a message or invite me to your AI agent project.

🚀 Expert-Vetted (top 1% of talent on Upwork) | 200+ ecommerce clients in 9 years 🚀 150M+ USD generated for clients across Email/SMS, Google Ads, and CRO 🚀 Featured in WSJ best-seller "Never Lose an Employee Again" alongside Adobe, Intuit, and LEGO 🚀 320+ episodes of The Ecom Show podcast (guests: Ezra Firestone, Patagonia, Shopify, Beardbrand, Nick Shackelford) ======== Most ecommerce brands don't have an email problem, an ad problem, or a CRO problem. They have a systems problem. The email person doesn't know what the ads are saying. The Google account runs blind without CRO support. The site was redesigned once and never touched again. Revenue leaks at every handoff. I fix the system - not just the channel. ======== 📞 Invite me to your project and we can review your ecommerce marketing strategy together at no cost. 📞 ======== WHAT I DO 1. Email & SMS Marketing (Klaviyo-heavy) Flows, campaigns, segmentation, deliverability, and lifecycle systems built to drive 30–40% of total revenue. → $9.4M generated from email alone for a high-ticket ammo brand (58.77% of total revenue) → $2.84M in 30 days from email + SMS for a US electronics brand → $1.3M from Klaviyo for a pet brand over 24 months 2. Google Ads (Search, Shopping, PMax, YouTube, Display) Full-funnel paid search built around profitable scale - not vanity ROAS. Tracking integrity, Merchant Center hygiene, GA4, feed optimization. → Peptides brand: $4.5K → $286K monthly revenue in 4 months ($426K total at 2.2x ROAS in a restricted category) → Automotive ecom brand: +94% ROAS on PMax, +810% ROAS on Shopping campaigns in 3 months → Healthcare clinic: CPA cut from $33 to $12 (–64%), clicks +300% on a $240K/month budget 3. CRO & Landing Pages. Prioritized roadmaps, A/B testing, PDP and checkout optimization. Hotjar, GA4, Shopify/WooCommerce. → AirBack: +44.21% CVR, +28.44% revenue (PDP redesign with sticky ATC, USPs, social proof) → Henry's Coffee: +37.82% CVR, +39.48% revenue (product selectors + mobile ATC) These three channels feed each other. Your Google search terms shape your email angles. Your flow data informs your next campaign offer. Your landing page performance dictates where ad spend gets allocated. One strategy. One operator. Zero gaps. ======== WHO I WORK WITH We can talk if you: 👉 Are doing $50K+/month and ready to invest in growth 👉 Are coachable (what you think will work often doesn't) 👉 Have a 3+ year plan (exit or cash flow business?) 👉 Sell multiple products 👉 Don't have time to learn and run email, Google Ads, and CRO yourself Probably not a fit if you're pre-launch, under $30K/month, looking for the lowest hourly rate, or want a one-off task instead of a strategic partner. HOW I'M DIFFERENT I've spent most of my 20s exclusively on marketing and business - psychology of how people actually buy, tens of thousands of dollars at conferences and masterminds, and 320+ podcast episodes with operators like Ezra Firestone, Molly Pittman, Beardbrand, Crossnet, multiple Shark Tank companies, and one of Alex Hormozi's CEOs. Behind me, I have a senior-led team covering: ✔️ Ecommerce growth strategy ✔️ Email & SMS marketing (Klaviyo, Mailchimp, Postscript) ✔️ Google Ads (Search, Shopping, PMax, YouTube) ✔️ CRO, product page, and landing page optimization ✔️ Marketing analytics (GA4, Northbeam, Triple Whale, Hyros) ✔️ Loyalty and referral programs What I personally handle: strategy, account direction, senior reviews, client calls. What my team handles: execution - copy, design, technical setup, QA, reporting. You work with me directly on strategy. My team handles execution at senior quality - never juniors. Featured on NBC, CNN, Forbes, BBC. Audited two Fortune 500 companies. Featured in the WSJ best-selling book "Never Lose an Employee Again" as a case study in high employee retention alongside Adobe, Intuit, and LEGO. ======== NEXT STEPS If you want senior-led ecommerce growth across email, Google Ads, and CRO - run by an operator who'll treat your budget like it's my own money: 𝗙𝗲𝗲𝗹 𝘄𝗲 𝗺𝗶𝗴𝗵𝘁 𝗯𝗲 𝗮 𝗴𝗼𝗼𝗱 𝗺𝗮𝘁𝗰𝗵? 🫶 Share what you need help with and your current monthly revenue Want to learn more first?

I am a Shopify, WooCommerce, and WordPress developer specializing in stores and sites that need to work reliably as they grow - larger catalogues, higher traffic, and more systems running in parallel. My work spans three platforms equally - Shopify, WooCommerce, and WordPress - and the strength is in knowing all three well enough to recommend the right one for the situation, not just defaulting to a single tool. On the Shopify side, this means custom theme development, Liquid customization, app integrations, and API work. On the WordPress and WooCommerce side, this includes custom theme and plugin development, Elementor and Divi builds, Advanced Custom Fields (ACF), Gutenberg blocks, and full WooCommerce store builds. I also handle migrations between platforms - Magento, WordPress, or WooCommerce to Shopify and vice versa - when a business outgrows its current setup and needs to move without losing data or downtime. Most clients come to me at one of three points: they are building a new store or WordPress site and want it done properly from the start, they are migrating from an older platform like Magento or a legacy WordPress setup and need it done without data loss or downtime, or they have an existing store with performance issues, broken integrations, or a checkout flow that is costing them orders. What I work on: ▸ Custom Shopify and WooCommerce store development - theme builds, Liquid customization, custom plugin development ▸ WordPress development - custom themes, Elementor and Divi builds, ACF, Gutenberg blocks, and custom plugin development beyond what standard builders can handle ▸ Ecommerce platform migration - Magento, WordPress, or WooCommerce to Shopify, and vice versa ▸ Shopify and WordPress speed optimisation, Core Web Vitals, and checkout conversion improvements ▸ Payment gateway setup and customisation - Stripe, PayPal, Klarna, and region-specific providers ▸ API integrations - CRM, ERP, inventory management, shipping, and fulfilment systems ▸ Debugging and fixing broken themes, apps, and plugins across Shopify and WordPress ▸ AI tool integrations - product recommendation engines, chatbots, and automated workflows ▸ Store and site restructuring for scalability, maintainability, and long-term performance Tech: Shopify (Liquid, APIs, themes, apps), WooCommerce, WordPress, Elementor, Divi, ACF, Gutenberg, PHP, JavaScript, REST APIs, webhooks, Stripe, PayPal, Klarna. Most projects involve product catalogues with multiple variants and SKUs, multi-currency or multi-region setups, and integrations with payment gateways, CRMs, or backend systems - where a broken flow has a direct impact on revenue. If you are building a store or site, planning a migration, or troubleshooting something that is not working the way it should, send a short outline of the situation and I will get back to you with a clear direction on next steps. Warm Regards, Harit Soni.

Over the past 21+ years I have worked across early web systems, enterprise software, blockchain platforms, and AI. These days I spend most of my time helping founders and product teams figure out what they actually need to build, and then building it with them. I enjoy making complex technology feel straightforward. That is something clients come back for. I have spent 10+ years deep in blockchain and the last few fully focused on AI. I can connect those two worlds in ways most developers cannot. Clients tell me they appreciate that I do not just execute tasks. I ask questions, flag things that have not been considered yet, and keep the bigger picture in view throughout the project.
