    On-Chain Invoice Financing

    Invoice financing is slow, opaque, and intermediary-heavy - SMEs wait 30-90 days for cash while factoring stays paperwork-bound and hard to audit.

    Content Pipeline SSG Platform

    Portfolio, blog, news digest, and quiz each needed the same material - content lived in multiple places, drifted apart, and publish was a manual ritual.

    Multi-Env CI/CD & Terraform Delivery

    Console-proven AWS hosting for four production domains still needed repeatable provisioning, environment isolation, and a release path that could promote the same four surfaces without long-lived AWS keys or rebuild-per-host chaos.

    Spaced-Repetition Quiz Engine

    Studying from personal notes meant a backend, an account, or a paid SaaS - with no algorithm swap and no reuse of the blog's content.

    AWS Multi-Subdomain Static Hosting

    Four independently deployable frontends needed production HTTPS subdomains with CDN delivery, private origins, and deep-link behaviour that matched how the apps actually emit HTML - without waiting on IaC or CI.

    Local Traefik Dev Stack

    Four monorepo frontends each wanted their own dev port; cross-site navigation broke, and nothing matched the real production domain topology.

    Personal Portfolio (V2)

    A hand-rolled static site could not keep up with typed collections, cross-cutting tags, SEO compliance, or a clean preview-vs-production release path.
