Built a full AI consulting business system — from website to outreach machine.
For a boutique AI consulting firm targeting mid-market companies in the US and Europe, I designed and shipped the full technical
stack:
Production website (React + TypeScript + Express)
Not just a landing page. A conversion machine: lazy-loaded routes, per-page SEO metadata, structured data for Google, a sitemap, an
OG image for social sharing, and Lighthouse-ready performance fixes (including a Framer Motion LCP bug that was silently tanking
search rankings).
AI Diagnostic Tool
A multi-step lead qualification form that calls Claude under the hood, generates a personalized automation ROI report for each
prospect, and delivers it at a unique URL — with prompt injection protection baked in (XML-delimited user inputs, system prompt
hardening).
Security layer
CSP headers, correct trust-proxy config for a Cloudflare + Railway dual-hop topology, hardened email notification logic, and temp
file cleanup that survives errors. Production-grade, not tutorial-grade.
LinkedIn prospecting engine
A Python + Playwright scraper that:
Rotates across 10 industry niches
Qualifies leads by title, location, and post recency
Auto-generates personalized connect requests (≤300 chars) and follow-ups via Anthropic API
Exports to Excel, deduplicates across runs
Currently targeting Property Management decision-makers in Florida & Texas
This is what "full-stack AI consulting infrastructure" actually looks like in practice.
What was built
A production-ready AI consulting business stack, covering six layers end to end.
On the frontend, a React SPA with TypeScript, lazy-loaded routes, per-page SEO metadata via react-helmet-async, and full
internationalization in English, Spanish, and Danish.
The SEO layer included a sitemap, robots.txt, JSON-LD structured data schemas for Google, a custom OG image at 1200×630px for
social sharing, and a performance fix for a Framer Motion bug that was silently blocking the page's Largest Contentful Paint —
meaning Google couldn't properly index the main headline.
The backend is an Express + TypeScript API deployed on Railway, hardened with Content Security Policy headers, correct trust proxy
configuration for a Cloudflare + Railway dual-hop topology, and proper temp file cleanup that survives errors.
The AI feature is a multi-step diagnostic form that sends the prospect's business data to Claude, generates a personalized
automation ROI report, and delivers it at a unique shareable URL — with prompt injection protection built in so user-submitted text
can never hijack the LLM's instructions.
On the security side, all user-controlled fields are wrapped in XML delimiters in the prompt, environment variable handling was
hardened to eliminate silent fallbacks, and no sensitive data leaks through error paths.
Finally, the outreach system is a Python + Playwright scraper that rotates across industry niches, qualifies leads by title,
location, and post recency, then uses the Anthropic API to generate personalized LinkedIn connect requests and follow-up messages
for each lead — exporting everything to Excel with deduplication across runs.
Key technical problems solved
LCP blocked by Framer Motion: opacity:0 on H1 prevented Google from indexing the headline. Fixed by rendering plain HTML on first paint.
Prompt injection risk: All user-submitted fields wrapped in XML delimiters + system prompt instruction to treat them as data, not commands.
Dual-hop proxy misconfiguration: trust proxy: 1 was wrong for a Cloudflare → Railway topology. Corrected to 2 to get real client IPs in logs and rate limiting.
Location-aware lead qualification: Scraper's filter system refactored to support per-niche target_locations, enabling pivot from Danish to US markets without touching core logic.

Our goal was to make pricing, inventory and ordering data feel simple and human for an AI-powered B2B commerce platform. We'd love to hear your thoughts!
Engaging background and nice gradient to not make the section look seprate 🔥
Just finished building a Salon Booking Management System!
The goal was simple: make appointment management easier for salon owners and reduce the manual work involved in handling bookings and reminders.
The system connects the complete workflow in one place:
1 Customer makes a booking
2 Booking gets confirmed
3 Owner sees it on the dashboard
4 Upcoming appointments are organized clearly
5 Reminders help the owner stay on top of appointments
One of the key things I focused on was making the experience simple, clean, and easy to understand, while keeping the workflow practical for a real business.
This project helped me think beyond just building screens — and focus more on the actual business problem, user flow, and overall product experience.
Excited to keep improving it and turn it into an even more polished product.

Good work
Marlowe Mobile Detailing
Solo-owner mobile car detailer, Austin, TX (serving Round Rock, Cedar Park, and Lakeway)
Marlowe Mobile Detailing was losing about 1 in 5 bookings to no-shows and running behind on nearly every job. This build replaces a vague "can you detail my car?" text with a fully scoped, weather-aware booking flow that sets an accurate time and price upfront, captures access instructions before he arrives, and automates rain-day rescheduling so he never has to chase a customer again.
He works alone and travels to the customer. Rain cancels outdoor jobs. Customers under-describe how dirty their cars are, so jobs run long. About 20% of bookings were no-shows because people forgot he was coming to them.
