DocFlow: Proposal Workflow with Word/PDF Generation and Approvals (FastAPI + React)
Portfolio demo: a proposal workflow for a fictional consultancy. An author writes the scope and fees, a background worker generates Word and PDF documents from a versioned template, and an independent reviewer approves one exact revision. Changing an approved proposal creates a new draft, so earlier approvals and files stay in the revision history. Durable database-backed job queue with leases, retries and fencing; content and file hashes pinned to each approval. Python, FastAPI, SQLAlchemy, PostgreSQL, React/TypeScript and LibreOffice. 35 backend tests against real PostgreSQL and LibreOffice, with the full Docker workflow checked in CI. Open source.

Local developer tool that executes atomic commit plans through a dual-agent AI pipeline (Generator & Reviewer) with real-time SSE streaming, quality gates, and automated rollbacks.
The dual agent pipeline creating atomic commit plans and the live SSE stream makes the review loop feel almost instant.
A fast, easy-to-manage portfolio website, built the way I build business websites for clients.
The site runs on Next.js with Server Components, so pages arrive with their content already in place for visitors and search engines. All content, including projects, services, experience and contact details, is managed in Sanity CMS. Updates happen in a dashboard, not in code, so no developer is needed for each change.
What went into it:
Next.js, React 19 and TypeScript for the foundation.
Tailwind CSS v4 and shadcn/ui for a consistent, responsive design system.
Framer Motion and GSAP for scroll animations that guide attention.
AVIF and WebP images at multiple sizes for lighter pages.
A server-side contact form with validation and email delivery through Resend.
Finally it was deployment on Vercel.😍
Test results: performance grade 83, 923.6 KB total page size, 2.16 s load time, 25 requests.
If you need a business website, e-commerce store or landing page with a CMS you can manage yourself, this is the kind of build you can expect.
Showing the stack next to the live site makes this read like a real case study.
A Webflow template for a new-build residential development: one sales page that takes a buyer from first impression to enquiry.
Includes residence types, a floor-plan browser filtered by apartment type, an availability table that switches to cards on mobile, a gallery, specification, location, FAQ and an enquiry form with residence preference. Plots and floor plans run on the CMS, so a sales team can update prices and status without touching the layout.
Built on reusable components and a variables-based style system, with a style guide page, SEO meta and Open Graph setup, and responsive behaviour across all breakpoints.
Concept project — brand and content are fictional.
