I build with AI as a force multiplier — architecting in Cursor with Claude, GPT and Composer, then reviewing and testing every line before it ships. Production-grade code at unprecedented speed, without sacrificing quality.

About Me

Engineering Business Software That Works

Former agency CEO. Lead architect. Automation expert. AI-accelerated delivery.

Having scaled a digital agency to 300+ deliveries and bootstrapped 9 commercial SaaS products across three international markets, I bridge the gap between business strategy and bulletproof engineering. Clients come to me when integrations break, automation doesn't scale, or the deadline simply cannot move.

I served as Lead Architect for an international agency where I managed a team of 10 professionals. Today I operate as a freelance architect via Upwork and my US LLC — while in parallel building and scaling the Devikit plugin ecosystem across the UK, France, and Poland. That means every client project benefits from production-tested code, real API integrations, and the same rigor I apply to my own commercial software.

Async-first by default — written updates, documented decisions, and fast execution without calendar overhead. Calls when they add value: kickoffs, complex scoping, and final reviews.

Enterprise AI Support Chatbot Agent

A production-grade chatbot pipeline that remembers every conversation in Redis, looks up the customer in HubSpot, classifies intent with OpenAI, and routes to specialized agents — billing pulls Stripe invoices, technical queries search a Pinecone knowledge base with tool-calling, sales creates HubSpot deals. When confidence drops or the user asks for a human, it hands off to Slack and Intercom. Errors trigger a fallback reply and PagerDuty alert, with every turn logged to Google Sheets.

Airtable + Claude AI Operations Hub

Incoming requests land in Airtable — AI reads each one, decides how urgent it is, and routes it automatically. Hot cases go to Slack and on-call alerts, warm leads get a drafted email and CRM note, cold ones enter a nurture sequence, and research items get enriched and logged. No more manual triage.

Automated Offer Generation — Pipedrive → Google Slides

When a deal moves forward in Pipedrive, the system pulls products and client data, fills a Google Slides template, and generates a ready-to-send offer. It updates the deal status and can attach a WooCommerce discount code — quotes that used to take an hour now take seconds.

Contract Generation Pipeline — Pipedrive → Google Docs

When a deal is ready to close, the system reads line items from Pipedrive, merges client and company data into a Google Docs contract template, and saves the finished document back to the deal. One click in CRM instead of copy-pasting into Word for every agreement.
