Multi-document AI knowledge base with cross-source citations
Problem: Internal knowledge — policies, contracts, onboarding docs — is scattered across files nobody can search, so answering a simple internal question takes minutes of manual digging or a person to ask.
Approach: Built a RAG system that ingests multiple documents into one searchable knowledge base and answers plain-English questions with the exact source cited — including questions that require pulling and synthesizing facts from two different documents at once.
Outcome: Stress-tested against a dense, realistic document set, answers that used to take minutes of manual search now return in seconds, correctly cited, including answers that span multiple source documents.
Tools: Next.js, Voyage AI embeddings, Supabase + pgvector, Groq Llama 3.3 70B

Modern businesses don't just need developers.
They need people who can understand the business problem, design the product, build the technology, connect the systems, and automate the repetitive work.

Perch - Link-in-Bio Tool Landing Page
A marketing site for a link-in-bio product built for creators, with pricing, platform integrations, and a Pro upsell all pulling their weight.
Live Preview
100/100 PageSpeed Insight Score: Mobile | Desktop
Perch is a concept marketing site for a link-in-bio tool, the kind of product creators use to turn one link into a hub for everything they make. The hero sells the core promise fast... "one link for every story you share"... backed by real customer-logo social proof.
From there the page builds out the actual reasons a creator would pick this over the dozen other link-in-bio tools out there: a "start from a theme, then make it entirely yours" customization pitch, direct integrations with the platforms creators already live on (Spotify, YouTube, TikTok, Twitch), and a dedicated Pro section covering unlimited pages, custom domains, and real subscriber growth tools. A trusted-by section with named creators closes the credibility loop before the pricing pitch even lands.
This build also went through a deliberate image weight fix worth calling out specifically... the testimonial and mockup imagery dropped from 9.6 MB to 264 KB, alongside fixes for seven contrast failures and a full set of security headers (CSP, HSTS, COOP, XFO). SEO and image-weight fixes are complete and shipped; a fresh PageSpeed scan against the redeployed site is the one remaining step before final numbers are locked in.
It runs as a single Cloudflare Worker with static assets, with a working signup form backed by D1, spam protection, and rate limiting, so a client could connect the repo and deploy without wiring anything by hand.
The performance work here is just as impressive as the visual execution. Taking the imagery from 9.6 MB down to 264 KB while also addressing accessibility and security headers shows real attention to the details that matter beyond the UI. Great build.
