About Ignacio (IGNAX)

I'm Ignacio (IGNAX) — a solo full-stack developer and SEO/AEO specialist, Spain-born and Paraguay-based. This page is the long-form version of who I am, what I build, and how I work with founders and agencies.

Who am I?

Spain-born. Trained as a developer in Spain, then moved to London where I worked as a Freelance Web Developer & SEO from 2019 to 2022. After three London years I joined a Web3 platform (Origin / EOS Titan) as Full-Stack Dev & AI from 2022 to 2024, shipping blockchain games, P2P crypto exchanges, and AI-powered tooling. Since 2024 I have been independent again, working with founders globally from Asunción, Paraguay.

Five-plus years of production work, bilingual EN/ES at native level. I care about clean code, straight communication, and shipping what I promise. Code that works and shipping fast — that is the standing brief.

What do I build?

The work falls into four overlapping areas:

• SaaS MVPs. End-to-end product builds for founders who have validated the problem and need the real thing. SvelteKit or React on the front, Node.js or Python on the back, Postgres for data, Stripe for billing, and one defensible feature (usually AI or automation). See my SaaS MVP service.
• AI automation. Python workers that replace manual back-office tasks — sales triage, doc parsing, support tagging, content generation. OpenAI and Anthropic by default; RAG pipelines on pgvector. See AI automation.
• SEO + AEO setup. Technical foundation work — schema, llms.txt, IndexNow, FAQ blocks, hreflang clean sitemaps, Quick Answer blocks. Get ranked in Google and quoted by ChatGPT, Perplexity, Gemini, Claude. See SEO + AEO setup.
• Blockchain. Solidity on EVM chains, Solana with Anchor when the brief requires it. P2P exchanges, multiplayer blockchain games, NFT pipelines.

I also subcontract white-label for studios and agencies needing a senior full-stack dev under NDA, day-rate.

What's my background?

The compressed timeline:

• 2019 — 2022, Freelance London. Web Developer & SEO. Built marketing sites and small SaaS for UK and EU clients. Picked up the SEO trade hands-on — technical audits, schema, multilingual setups. Three years that taught me both shipping code and getting it found.
• 2022 — 2024, Origin / EOS Titan. Full-Stack Dev & AI. Shipped production blockchain products — P2P crypto exchange on Polygon, multiplayer Solana game, AI support chatbots, automated video pipelines. First serious production-scale AI work, mixed with on-chain integrations.
• 2024 — Present, Freelance Global. Independent again, now based in Paraguay. Building SaaS MVPs, AI automation, SEO/AEO setups, and white-label subcontracting for agencies. Clients in the US, UK, Spain, and across LATAM.

Seven-plus shipped projects across SaaS, AI, blockchain, and content platforms. One currently live SaaS that I still operate.

What's my stack?

The default stack — the one I reach for when a client doesn't specify:

• Frontend: SvelteKit + TypeScript, or React + Vite + TypeScript. Tailwind for styling. Fully typed, accessible by default, SSR for SEO.
• Backend: Node.js (Fastify, Hono) for tightly typed full-stack work; Python (FastAPI) when there is meaningful AI/ML code in the loop.
• Database: PostgreSQL on Supabase or Neon. Migrations versioned in git. pgvector for embeddings.
• AI / LLMs: OpenAI and Anthropic via managed APIs by default. RAG pipelines on Postgres + pgvector. Prompts versioned in code.
• Blockchain: Solidity for EVM chains (Ethereum, Polygon, Arbitrum). Solana with Anchor.
• Hosting: Cloudflare Pages + Workers for global edge; Fly.io or DigitalOcean when stateful workloads need it; AWS when the client requires it.
• Payments: Stripe (Checkout, customer portal, webhooks, Stripe Tax).
• APIs: REST by default, GraphQL or tRPC when scope warrants.

If a client is committed to a different stack — Next.js, Django, Rails, .NET — I match it. The architecture pattern travels.

Where am I based and what are my working hours?

Asunción, Paraguay. GMT-3 year-round — Paraguay does not observe daylight saving time, which matters for clients who need a stable recurring overlap.

Working hours: Mon–Fri, 8:00–17:00 PYT (GMT-3). Weekends off. Overlap with US East 7:00–16:00 EST, with Madrid 13:00–22:00 CET.

That gives a US East client a full workday overlap and a European client four hours of afternoon overlap. Async-first by default — Slack, Linear, GitHub, Loom — with sync calls when they earn their place.

How do I work with clients?

The flow is short on ceremony, heavy on shipping.

1. Intake. Email hello@ignax.dev with a one-paragraph description of the project and the rough budget band.
2. Discovery call. Free, 30 minutes. We agree on the one feature that matters and the three that can wait.
3. One-page spec + fixed quote. Within 48 hours of the discovery call. If the spec is not workable I tell you in the call.
4. Build. Daily commits to your repo from day one. Friday Loom video showing what runs. No scheduled standups.
5. Ship. Production deploys go to your own cloud accounts. You own the GitHub repo, the database, the domain.
6. Post-launch. Two-week fix window on the original scope. Optional 20-hour/month maintenance bucket at 15% off hourly, 30-day rolling cancel. No retainer lock-in.

The default contract is plain-English MSA + SOW. Your jurisdiction or mine, your call. Payment in USD via Wise, Stripe, or international wire; PYG for Paraguay-based clients. NET-14 by default, milestones for projects over $5K.

How do I work with agencies?

White-label senior full-stack developer or SEO/AEO consultant under your brand and NDA. Day-rate option: $240–$560 USD/day (derived from the hourly band). I sign your NDA, use your email if needed, and stay invisible to your client. I bill weekly, deliver weekly, and never reach out to your client unless you ask me to.

Common use case: your team is at capacity, you have a backlog, your seniors are burning out. I plug in as senior subcontractor for the MVP track or the SEO/AEO setup track. EN/ES bilingual coverage included — useful when you have LATAM or Spain clients but an English-only team.

How can you reach me?

• Email: hello@ignax.dev — one paragraph, one business day reply.
• GitHub: github.com/ignaxdev — code samples and active repos.
• Live methodology proof: The site you're reading is the ongoing meta-case-study. The ignax.dev growth engine tracks Day-0 baseline through monthly public updates.

For broader context on the work, the Y Combinator startup library and Stripe Atlas guides are the founder-facing references I send most often. For SEO methodology I work against Google Search Central and Schema.org documentation as canonical sources.
