Still managing your Amazon business manually through Seller Central? I build custom integrations using Amazon SP API, Ads API, and Shopify API — and layer AI on top to make them intelligent. 100+ integrations delivered. I help sellers, agencies, and SaaS companies automate what the Amazon console can't: Amazon SP API Automation Orders, inventory, pricing, listings, feeds, reports, notifications, and FBA/MFN workflows — fully automated end-to-end. I handle LWA authentication, rate-limit management, token refresh, and error handling so you don't have to. Amazon Ads API Optimization Programmatic campaign management for Sponsored Products, Brands, Display, and SB Video. Bid automation with custom rules (ACoS/ROAS targets, time-of-day logic), search term report pipelines, negative keyword harvesting, budget monitoring, and automated dayparting. Agency-grade multi-account support included. Shopify API Integration Real-time bi-directional inventory sync between Shopify and Amazon. Unified order management, product data mapping across platforms, webhook-driven fulfillment routing, and custom Shopify app development. I connect both platforms so they work as one. AI Agents and MCP Server Development This is where I go beyond what other API developers offer. I build Model Context Protocol (MCP) servers that let AI models like Claude and GPT query, analyze, and act on your live Amazon and Shopify data. Imagine asking "What were my top 5 ASINs last week?" and getting an instant answer from real data — or having an AI agent that monitors your ad campaigns and auto-pauses underperformers when ACoS spikes. I also build custom AI workflows: automated chains that pull data, analyze trends, make decisions, and take actions without human intervention. Deploy your AI agent on Slack, Discord, Web, or Claude Desktop. Data Pipelines and Reporting Connect Amazon and Shopify data to ERPs, custom dashboards, Google Analytics, and BI tools. Scheduled reports, real-time syncs, and unified analytics across all your channels. Tech Stack PHP, Laravel, Node.js, Python, MCP Protocol, Claude API, OpenAI API — I work with whatever your existing system uses. All integrations include production-ready documentation, error handling, and deployment support. Why clients choose me: - 100+ successful integrations across North America, Europe, and Asia - 5-star reviews on every platform I work on - I don't just connect systems — I make them think - Fast communication and delivery with no surprises Ready to automate? Message me with your requirements. I'll review your setup, scope the project properly, and recommend the most efficient architecture. No generic solutions — every integration is tailored to your business.

I have managed over $100M in ad spend, recovered $50M+ in hidden profit leakage, and scaled more than 300 e-commerce brands. Whether you have a strict ACoS target to hit, a new product launch to nail, or a significant budget that needs to be deployed intelligently, my team and I have the experience to execute it. We are a highly focused, boutique agency. We do not outsource, and we are not a large BPO where your account gets handed off to a junior account manager. When you work with us, you work directly with me and my core team. That team includes former Amazon employees, professionals with 15+ years of digital marketing experience, MBAs, and founders who have built and successfully exited their own e-commerce businesses. I am a PhD-trained researcher (University of Washington) specializing in consumer decision-making. We combine a deep understanding of buyer psychology with disciplined, data-driven architecture to hit your KPIs. Our Core Capabilities: 1. Amazon Advertising Management (PPC & DSP) We build and execute full-funnel strategies across Sponsored Products, Brands, Display, and DSP. We structure campaigns to acquire new customers at a profitable CAC while protecting your organic rank. Context: We recently deployed a targeted strategy for a supplement brand, scaling them from 38% to 22% ACoS while tripling their daily unit volume to generate $7.1M in 4 months. 2. Profit Recovery & Audits Amazon's fee structure is complex, and errors happen constantly. We run deep forensic audits across 12+ claim types to identify lost inventory, overcharged fees, and unclaimed reimbursements, managing the entire recovery process. Context: We recently recovered nearly $165,000 in a single audit for a client. 3. Brand Health & Listing Optimization As Amazon's search algorithm evolves with AI systems like Rufus and Cosmos, traditional SEO tactics are obsolete. We resolve suppressed listings and structure your copy to index perfectly for Amazon's algorithms while converting human buyers. Context: We revived a suppressed ASIN within a week that was losing $33,000 a day in sales (and leaked over $1.6M before we got hired) How We Work We operate as a strategic extension of your business. If you are an established brand generating at least $500K+ annually and you need a dedicated, senior-level team to hit your targets, send me a message. We can set up a brief call to look at your account, discuss your objectives, and determine if we are the right team to help you reach them.

My team and I have delivered production systems for Tinuiti, Pixis, BTR Media, and Amazify over the past 10 years. My work covers two areas most developers treat separately. On the data engineering side I build real-time pipelines, ETL systems, and automated reporting for platforms processing millions of events and 100K+ SKUs daily. On the full-stack side I architect multi-tenant SaaS products, API-first backends, and the dashboards that sit on top of all that data.

PPC optimization and automated bid management systems. Sales, profit, attribution, and inventory dashboards. ETL pipelines and large-scale data processing. Multi-tenant SaaS architecture with RBAC and SSO. OpenAI and AI integrations for document intelligence and workflow automation. At Tinuiti I worked on a platform managing hundreds of millions in ad spend with automated bidding, real-time attribution, and cross-channel reporting across Amazon, Google, Walmart, and Meta. At Pixis the work involved AI-driven campaign management at massive scale across multiple enterprise clients simultaneously. At RAGAdvise I built the full multi-tenant SaaS architecture from the ground up. Tech stack: Python, Node.js, Laravel, ASP.NET, React, PostgreSQL, AWS (EC2, S3, RDS), Looker Studio, Data Studio, OpenAI, CI/CD, DevOps. If you are an ecommerce brand, performance marketing agency, or SaaS company that needs serious infrastructure built right, let's talk.

  • Industry fit. You want an Amazon MWS developer who understands your industry so they can help you figure out how best to reach your target market.
