Developer Tools Hub
Architect & Engineer — Solo Project
A production developer utilities platform on its own subdomain (tools.augustomoreira.com) — 74+ free browser-side tools spanning formatting, encoding, generation, conversion, calculation, image processing, PDF manipulation, and video/audio editing, all running client-side with zero server computation. Built with full SEO instrumentation, security hardening, and automated CI/CD at zero additional infrastructure cost.
Completed April 2026
Key Impact
- ✓ 74+ free browser-side tools — zero server computation, instant results
- ✓ Full SEO instrumentation: schema.org, OG, XML sitemap on every tool page
- ✓ Launched at zero additional infrastructure cost on existing cloud resources
Built Solo.
Deployed to Production.
Used Daily.
Every tool processes data entirely in the visitor's browser — no inputs ever leave their machine. That's not just a privacy win; it means the platform scales to any traffic with zero additional infrastructure cost per user.
- Designed, engineered & deployed by one person
- SEO-optimised — sitemaps auto-generated from config
- Zero data sent to any server, ever
- Always free — no account, no paywall
A fully-featured developer utilities platform live at tools.augustomoreira.com — designed to attract organic search traffic, convert visitors into recurring users, and serve as a public demonstration of product engineering capability.
The Product:
• 74+ free, instant-use tools covering every common developer and everyday task: JSON & SQL formatting, Base64 & URL encoding, JWT decoding & building, regex testing, password generation, QR code creation, colour conversion, unit conversion, image compression, PDF manipulation, video & audio editing, financial calculators, and much more.
• Every tool runs entirely in the browser — no sign-up, no data sent to any server, no loading spinners. Results are instant.
• Tools are grouped into nine categories (Formatters, Encoders, Generators, Converters, Testers, Image Tools, Calculators, PDF Tools, Video & Audio) for intuitive navigation.
• Video and audio tools powered by FFmpeg WebAssembly — full media processing (trim, compress, convert, crop, extract audio) running locally with no cloud upload.
• PDF cluster built on PDF.js and pdf-lib — merge, split, reorder pages, convert images to PDF, and run OCR entirely in-browser.
• Designed to be expanded: adding a new tool requires a single configuration entry and a view file — no database changes, no redeployments of additional services.
SEO & Discoverability:
• SEO-first architecture — each tool page targets high-volume search queries (“json formatter online”, “regex tester”, “uuid generator”) for compounding organic traffic.
• Schema.org structured data, Open Graph, Twitter Card, and auto-generated XML sitemap on every page to maximise search visibility and social shareability.
• Cross-promotion — tools visitors are one click away from the main portfolio, creating a natural lead funnel.
Security & Trust:
• All processing happens in the user’s browser — no user input ever reaches the server, eliminating entire classes of data-handling risk.
• Enterprise-grade security headers on every response: strict Content Security Policy (including WASM and media-source directives), anti-clickjacking, MIME-type protection, and DDoS mitigation via Cloudflare.
• GDPR-compliant privacy policy confirming client-side-only data processing with no user inputs sent to any server.
• Automated security audit on every code push; third-party dependencies kept to an absolute minimum.
Engineering Efficiency:
• Launched on a dedicated subdomain with its own TLS certificate and CDN layer — at zero additional infrastructure cost by reusing existing cloud resources.
• Single CI/CD pipeline covers both the portfolio and the tools hub; the entire platform deploys in one operation.
• Fully automated test suite validates every tool page, every SEO tag, and the integrity of the tool registry on every commit.
