Cover image for BriefHaven is a full-stack SaaS
BriefHaven is a full-stack SaaS platform I built to solve a real problem for freelancers and agencies: chasing clients for project details, files, and approvals across scattered emails. It gives clients a single secure portal link — no account or password required — where they can fill in structured project briefs, upload files, exchange comments, and approve deliverables, all in one place. What I built: Secure, per-client portal links with email-verification (OTP) login — no passwords Structured brief-collection forms with client review/approval workflows File upload pipeline with virus/malware scanning Threaded comments between freelancer and client Automated email notifications for key events (new brief, new comment, approval requests) Billing integration (Lemon Squeezy) Stack: Next.js, TypeScript, Supabase (Postgres, Auth), Cloudflare R2 (file storage), Vercel (hosting), Transloadit (upload processing) Why it matters: This project shows what I can build end-to-end — from database schema and auth flows to file handling, transactional email, and billing — as a solo, AI-assisted full-stack developer. If you need a SaaS product, internal tool, or client-facing portal built from scratch, this is representative of the kind of work I deliver. Live: getbriefhaven.com (http://getbriefhaven.com)

Cover image for 🚀 A multi-tenant booking SaaS
🚀 A multi-tenant booking SaaS shown end-to-end From the product site that sells it, to the white-label site each business gets, straight to the dashboard that runs it all. 🤖 How it works: Customers book by chatting with an AI assistant in a messaging app. Every booking carries the channel it arrived through, turning chat conversations into a highly visible, organized agenda for the business owner. 📊 The Admin Panel: Live Analytics: Complete with an occupancy heatmap. Full Agenda Management: Create, reschedule, confirm, complete, or mark as no-show. Smart Operations: An auto-built customer CRM (generated directly from bookings), catalogue & staff management, and bot-collected reviews. Real-World Flexibility: The owner can force an appointment on top of another. Barbershops squeeze people in every day, and software that forbids it simply gets abandoned. 🛠 The Tech Stack: Frontend: Vite + React 19 + HeroUI v3 Backend: FastAPI (Python 3.14) on PostgreSQL Static Sites: Astro hosted on Cloudflare Monetization: Stripe subscriptions with a 30-day trial Data Integrity: No double-booking is guaranteed by a robust database exclusion constraint, rather than just relying on the interface. 🌍 Status: Live in production and successfully taking real appointments for a barbershop in Zaragoza.

Cover image for Recruiters sit on hundreds of
Recruiters sit on hundreds of CVs they can't search. Keyword search misses the obvious — the candidate wrote "React", you searched "frontend", they never surface — and every AI tool that fixes that ships candidate data to a third-party API. I built RecruitSecure AI to do the semantic search without the API call. The embedding model runs server-side through Transformers.js (quantized multilingual-e5-small, 384 dimensions, 100+ languages), so you can ask in Spanish and it finds CVs written in English — and nothing ever leaves the deployment. Drop in PDFs or DOCX and it extracts name, email, skills and experience, indexes each CV as a vector, and answers plain-language queries like "frontend lead who has built a design system": ranked by relevance, each result showing the exact CV fragments behind the match, so the recruiter sees the reason and not just a score. Retrieval is hybrid — pgvector HNSW cosine fused with BM25 full-text through Reciprocal Rank Fusion, then re-ranked from the recruiter's own thumbs up/down. Next.js 16, React 19, strict TypeScript, PostgreSQL + pgvector through Drizzle ORM, Auth.js, Stripe subscriptions, multi-tenant with AES-256-GCM encryption at rest and GDPR export and deletion. Built solo, end to end. The video is the real application: ten synthetic CVs uploaded through the actual pipeline, extracted, embedded and searched. Nothing staged.

Cover image for A health-tracking Android app for
A health-tracking Android app for logging blood pressure, oxygen, pulse, glucose and weight — designed for elderly users first. Oversized one-digit-at-a-time keypad, high-contrast readings, and a one-tap printable report their doctor can actually read. Medication list that keeps withdrawn drugs visible in red instead of hiding them, so nobody takes one by mistake. Offline-first: the database lives on the device and never leaves it unless the user syncs it to their own LAN server. Built with Expo/React Native in strict TypeScript across 15 languages, with speech input, a marketing site in Astro on Cloudflare Pages behind a hash-pinned CSP, and a Hono + SQLite sync server with last-write-wins reconciliation.

Cover image for DevFlowAI is a free, open-source
DevFlowAI is a free, open-source suite of 20 developer tools — several powered by AI — that speed up everyday coding work in one fast, polished web app. From regex building and JSON formatting to JWT decoding and AI-assisted commit messages, it puts the utilities developers reach for daily behind a single, clean interface. I built it end to end in Next.js 16 and React 19 with strict TypeScript, shipped as an installable PWA in 8 languages. I held it to a hard quality bar: a perfect 100 / 100 / 100 / 100 Lighthouse score (performance, accessibility, best practices, SEO), WCAG AAA accessibility, and full CI/CD with automated security scanning (CodeQL, Semgrep, SBOM). It's live at devflowai.dev (http://devflowai.dev) and fully open source — a working demonstration of the standard I ship at: fast, accessible, tested, and production-grade.

Cover image for Company Brain. Facts you can
Company Brain. Facts you can trust from several sources Problem Small teams live in chat and notes. Prices, owners, and status drift across threads — and nobody has one place that stays true. What I built Company Brain: email, meetings, and Slack feed into structured facts. When something conflicts, it lands in a simple review inbox for a quick human check — not another wiki. Result Decisions stop drifting. The team gets searchable facts with a human still in the loop; pilots start white-glove and scoped.
