Over the past 5 years I've solved AWS infrastructure issues that had stumped engineering teams, built and managed complete AWS environments from the ground up, designed cross-account architectures, audited enterprise cloud environments, reduced cloud costs and built serverless systems from scratch. 𝗨𝗽𝘄𝗼𝗿𝗸 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 • 𝗔𝗪𝗦 𝗣𝗿𝗼𝗳𝗲𝘀𝘀𝗶𝗼𝗻𝗮𝗹 𝗖𝗲𝗿𝘁𝗶𝗳𝗶𝗲𝗱 I've worked on cloud infrastructure powering SaaS platforms used by organizations including Novartis, Roche, UBS, Bayer and Juventus. I mostly work with startups and growing SaaS companies, but I'm equally comfortable working with established teams on architecture, DevOps and production infrastructure.

I usually get involved when a business has one or more complex problems to solve. It might be a B2B or B2C platform that needs APIs, integrations, payments, or storefront work. I have spent around 350 hours developing and maintaining APIs for Fastkey and 200 hours managing a Replit project, its integrations, and ongoing development. However, this only reflects my work completed through Upwork. Outside Upwork, I have spent over half a decade working with Amazon, Shopify, Temu, WooCommerce, BigCommerce, custom storefronts, and eCommerce systems. I am comfortable building from scratch, fixing bugs, and continuing to scale live systems. Other builds include: ✅ Magento development and troubleshooting ✅ eCommerce systems covering catalogs, orders, payments, inventory, and fulfillment ✅ Connecting third-party platforms and APIs to retrieve and synchronize data ✅ Android kiosk solutions with remote management and device controls ✅ Paywall and payment integrations using RevenueCat, Stripe, and PayPal ✅ Setting up WordPress across multiple domains I keep the work straightforward. First, I understand how the business and current system operate. Then I make the technical changes without adding unnecessary complexity. If your project needs someone who can work across the complete system rather than only one framework, feel free to get in touch.

Struggling to find a developer who can actually ship AI features into a real product? I've spent 20+ years building production software, and the last 2 years going deep on AI agents, RAG, and LLM systems that hold up under real traffic, not just in a sandbox. Full-Stack Development (Python and PHP): - 20+ years building and scaling production systems across both stacks - E-commerce & payment platforms, built to PCI-DSS compliance standards - High-traffic distribution/content platforms serving thousands of active users - Backend APIs, internal business tools, and automation scripts - Wrote code and led the engineers who wrote it, I know what "production-ready" really means DevOps, DevSecOps & SRE: - Cloud infrastructure across AWS, GCP, and Azure - CI/CD pipelines and Terraform for repeatable, safe deployments - Security built into the pipeline, not bolted on after (DevSecOps) - Uptime, monitoring, and fast incident response (SRE) - Disaster recovery planning for clean, fast system recovery - Bare metal server management and true 24/7 operations - Grew a NOC team from 2 engineers to 20+ - Python scripting to automate and tighten up ops work AI Agents, RAG & LLM Orchestration: - Voice AI agents handling high call volumes with 98%+ task accuracy - MCP (Model Context Protocol) servers connecting agents to real business tools - RAG pipelines with vector databases like Pinecone, pgvector to keep LLMs grounded in real data - Multi-step agent orchestration with LangGraph and n8n - Careful prompt engineering and tool-calling design - Full voice pipelines, speech-to-text, intent or slot-filling, natural text-to-speech Why clients hire me: Most freelancers offering AI work today are new to production systems. I'm not, I spent over a decade leading engineering teams of up to 500+ people, and I bring that same discipline to every build: security, observability, and a real plan for when things break, not just when they work. If you need code shipped properly, infrastructure that doesn't fall over, or AI that actually holds up under real usage, let's talk.
