Most AI projects fail after launch. They work in demos, but break when real users, real data, and scale hit.
I’m an AI Engineer who builds production ready AI systems that actually work and generate revenue. I design system with AI Automation, API Integration, and scalable Cloud Architecture on AWS so your product runs reliably, not just in theory.
You don’t need a full team to build and scale your product. I handle AI development, API integration, and cloud architecture end-to-end so you move faster with fewer moving parts.
Over the last 8 years, I’ve worked across AI, backend, and cloud, building systems used by real
businesses:
→ AI recommendation engine serving 50,000+ Shopify stores with millions of daily requests
→ PCI-compliant financial platform with real-time processing and multi-tenant architecture

→ Scalable AI App Development using Serverless Architecture (AWS Lambda, Amazon Bedrock)
→ End-to-end API Integration across third-party services and platforms
→ Production-ready systems with proper CI/CD Pipeline, performance, and cost optimization
Why clients work with me:
→ Focus on production ready AI products, not prototypes or experiments
→ Strong in AI + backend + AWS (not just one piece)
→ Experience with systems handling millions of requests and real users
→ Clean architecture, scalability, and long-term maintainability
Core stack:

Amazon sellers lose thousands every week to data they can't see. Slow reporting, manual pulls across accounts, ad spend they can't track in real time. I fix that.
You're probably in one of these situations:
→ You manage multiple Amazon seller accounts and pull reports manually every week, spending hours on data that should be automatic
→ Your ad spend is growing but you can't see which campaigns are actually profitable across all your accounts in one place
→ You've outgrown spreadsheets and need a real analytics platform but off-the-shelf tools don't fit your exact data model
→ You're building a seller intelligence tool or ecommerce SaaS and need someone who has actually done this at scale
If any of these sound familiar, you're exactly who I work with.
𝗪𝗛𝗔𝗧 𝗜'𝗩𝗘 𝗔𝗖𝗧𝗨𝗔𝗟𝗟𝗬 𝗕𝗨𝗜𝗟𝗧
→ An automated Amazon analytics platform pulling 103 unique SP-API and Advertising API report types across 5 seller accounts. Sponsored Products, Sponsored Brands, Sponsored Display, FBA, Business Reports, Financial Events, Settlement. What used to take days now runs overnight automatically.
→ A seller intelligence platform comparable to Helium 10. SP-API integration, real-time competitive data via Keepa, historical pricing, inventory tracking, and analytics dashboards for serious Amazon sellers.
→ An automated ad analytics dashboard for a digital agency. Pulling live campaign performance across platforms, eliminating hours of weekly manual reporting, giving account managers real-time visibility instead of last week's data.
→ A multi-channel ecommerce connector framework. Shopify App Store integration, Etsy, Walmart, and Wix all connected through one unified system, processing orders automatically across every channel.
𝗧𝗛𝗘 𝗣𝗥𝗢𝗕𝗟𝗘𝗠𝗦 𝗜 𝗦𝗢𝗟𝗩𝗘
→ Manual report pulling across Amazon accounts. I automate the entire pipeline so data is ready every morning without anyone touching it
→ Disconnected ad and sales data. I build unified dashboards that show exactly where money is being made and lost
→ SP-API rate limits and token management that break at scale. I've solved this across 5 accounts and 103 report types
→ Ecommerce tools that don't quite fit. I build exactly what your business needs instead of forcing a workaround
→ Growing seller operations that outpace spreadsheets. I build the infrastructure that scales with your business
𝗪𝗛𝗔𝗧 𝗬𝗢𝗨 𝗚𝗘𝗧
→ Automated data pipelines that run while you sleep. No manual pulls, no missed reports, no data gaps
→ Real-time visibility across all your accounts and channels in one place
→ Production-ready systems built for scale. Not prototypes that break at 1,000 orders
→ A developer who understands ecommerce operations, not just the technical side
→ Clear communication and proactive updates. You always know where things stand
𝗧𝗘𝗖𝗛𝗡𝗜𝗖𝗔𝗟 𝗦𝗧𝗔𝗖𝗞
→ Amazon SP-API, Amazon Advertising API, Selling Partner API
→ Python, Django, FastAPI, Flask
→ PostgreSQL, Redis, MongoDB
→ React, Next.js, TypeScript
→ AWS, Docker, GitHub Actions CI/CD
→ Shopify API, Etsy API, Walmart API, WooCommerce
→ Stripe, QuickBooks, Xero, NetSuite
→ Claude API, OpenAI, LangChain
𝗕𝗬 𝗧𝗛𝗘 𝗡𝗨𝗠𝗕𝗘𝗥𝗦
→ 9+ years building production Python backends
→ $100K+ earned on Upwork
→ 54 completed projects
→ 103 unique SP-API report types implemented across 5 seller accounts
→ Clients across US, UK, EU, and Middle East
If you're an Amazon seller, ecommerce operator, or SaaS founder who needs a developer that actually understands your data, send me a message describing your situation and I'll tell you exactly how I'd solve it.

As a React Developer and Full Stack Developer I build custom Web Application products for B2B clients, from interface to backend. Most of my work is Full Stack Developer React Node delivery, where a React frontend and a Node.js backend support one business workflow end to end. As a Node.js Developer I own the REST API logic, authentication, roles and permissions, and the data layer behind each product. My focus is practical Web Application Development that ships, scales, and stays maintainable, with clean API Integration at the core.
Across 14+ years and 130+ completed projects I have built 60+ SaaS, CRM and dashboard products, 40+ admin panels and client portals, and 200+ REST API integrations. As a React Developer and Full Stack Developer with experience leading development teams of up to 6, I have shipped for 50+ EU and US B2B clients across SaaS platforms, CRM systems, marketplaces, booking websites and API Integration projects.
As a React Developer I build Web Application interfaces with React.js, Next.js, TypeScript and Responsive UI , wired to live data through API Integration . As a React Frontend Developer and Frontend Developer I deliver usable, fast interfaces — data tables, filters, admin panels and client portals.
On the backend side, as a Node.js Developer and Backend Developer I build the REST API layer, ExpressJS services, authentication, roles and permissions, payment flows and CRM integrations. Many clients come to me as a Node.js Developer when a frontend already exists but the API, the data model and the business logic need to be done right. As a Backend Developer I keep the Node.js layer predictable and documented, and as a Node.js Developer I handle the API Integration between third-party services, the database and the frontend.
A typical Full Stack Developer React Node project for me looks like this: a SaaS platform or internal business tool with a React frontend, a Node.js backend, a structured database and an admin workflow for the team behind it. On every Full Stack Developer React Node build I design the database structure, the REST API , the dashboards and the permissions model so the product holds up as it grows. This Full Stack Developer React Node approach keeps frontend and backend in one system. Hiring one Full Stack Developer React Node engineer also keeps the React Developer and Node.js Developer decisions consistent across the whole build.
I also work as a Directus Developer and Headless CMS Developer . On 20+ content-driven and data-heavy products I use Directus CMS or Strapi as a headless backend, which gives clients a clean admin panel and an API-ready foundation. As a Directus Developer I model the data, set roles and permissions, and connect a React frontend through REST API ; as a Strapi Developer I do the same on Strapi. Headless CMS work with Directus CMS pairs naturally with my React Developer and Node.js Developer delivery.
Stack I use daily: React, React.js, Next.js, Node.js, TypeScript and JavaScript on the application side; ExpressJS, REST API and API Integration on the service side; SQL, MySQL, MongoDB, Firebase and Supabase for data; Directus CMS and Strapi for headless content. Authentication, roles and permissions, payment flows, dashboards, data tables, filters and admin workflows are standard parts of how I deliver Web Application Development .
How I work on a Full Stack Developer React Node project: discovery and scope first, then architecture and backlog, design where needed, development in sprints, QA on staging, production release, and support after launch. As a Web Developer with 14+ years behind me, my main promise is delivery predictability — clear scope and no surprises. As a JavaScript Developer I write code the next developer can actually read and extend.
Typical projects clients hire me for: SaaS platform development, CRM systems, admin panels, marketplaces, booking websites, lead generation websites, dashboards, client portals, internal business tools, e-commerce platforms and API-based Web Application work with workflow automation and business automation.
Clients also find me under related searches that match my real stack. On the React side: React Native Developer , React Native App Developer , React Next.js Developer , React Developer Firebase , and Full Stack Developer Supabase React . On the full stack side: Python Full Stack Developer , Full Stack Developer AI , Full Stack Developer Shopify , Full Stack React , Full Stack Node.js React and Node.js React . On the backend: Node.js Backend Developer and Back End Developer Node.js . I also fit Front-End Developer Full-Stack , Python Developer , WordPress Developer , Mobile App Developer and Senior Full Stack Developer .
If you need a React Developer , a Full Stack Developer React Node engineer, or a Node.js Developer for a serious product, I can take it from architecture through release and support. Let's talk about your product and what it needs to do.
