# Aguilera Engineering · Engineering Partner for founders shipping with AI > Staff-level engineer who ships AI features for small SaaS companies. Fintech-adjacent. Pragmatic, no hype. Engagements 1 week to a quarter. Site: https://aguilera.ee ## Engineering Partner for founders shipping with AI - Your AI demo works in the pitch but not in production? - Your engineers can't scale at your growth rate? - I drop in for 4–12 weeks and ship the feature **Eight years** shipping payments, data and crypto infrastructure that moved **millions of euros** across jurisdictions. Now applying that **discipline** to **AI** **Book a 30-min call:** https://cal.eu/aguilera/30min _No pitch deck. 30 minutes, scope-shaped._ I don’t sell AI transformation. I find where it fits in your product and your workflows, and then ship it. No 6-week discovery phase. Just working software. ## Who I work with. _A direct address. If this isn’t you, the rest of the page won’t matter much._ Founders of small SaaS companies. **5 to 25 people**, **seed to Series A**. Building products in fintech, accounting, compliance, payments, or financial operations. You’re non-technical, or lightly technical. You have one or two engineers and an AI feature your buyers are asking about. You want it shipped without a 6-week discovery phase, an account manager, or a junior dev doing the work. I drop in for a few weeks, ship the feature, write the docs, and leave your team better than I found them. ## What I work on. Three concrete shapes the work usually takes. Most engagements are a mix. ### Ship AI features to production Stuck demos, flaky retrieval, evals you don’t trust. I take prototypes the rest of the way. ### Fix the data and infra underneath Most AI projects break on data, not models. Pipelines, observability, reliability. The boring problems that decide whether your AI ships. ### Senior judgment when you need it Build vs buy. Engineer interviews. Architecture reviews. The ‘ask a senior’ call you’ve been making to friends, but contracted properly. ## Three ways in. Fixed scope, fixed timeline. Pricing handled on the call. No prices on the page; no statements of work that quietly grow. ### Tier 01 — Engineering Audit - **Shape:** 1 week, fixed fee - **For:** Stuck AI feature, pipeline mess, build-vs-buy - **You get:** A written diagnosis. Concrete recommendations. A roadmap. > Start here if you’re not sure what you need. ### Tier 02 — Engineering Sprint ★ - **Shape:** 6–10 weeks, project-priced - **For:** One scoped feature, shipped to production - **You get:** One feature. One price. One ship date. Docs and evals included. > For when you know what to build. ### Tier 03 — Growth Partnership - **Shape:** Quarterly, throughput-priced - **For:** Continuity after a successful sprint - **You get:** Scoped throughput. Senior judgment on tap. Direct contact. > For founders who want continuity. **Book a call:** https://cal.eu/aguilera/30min · 30 minutes · no obligation ## Testimonial > Eduardo is the engineer you hire when you need the thing actually shipped. He takes a problem from messy idea to production, makes the calls along the way, and leaves the team better than he found it. Direct, fast, no theater. — Dab Tech Solutions, CEO ## What I’ve built. Two paths to the same answer: shipped software you can try right now, and eight years of high-reliability production work before going independent. ### Shipped - **[Omnivu](https://www.daverlabs.com/omnivu)** — _Production · Live_ — Unified AI Platform that gives your organization secure, centralized access to OpenAI, Claude, Gemini, and Mistral - **[ShieldAI](https://www.daverlabs.com/shieldai)** — _Production · Live_ — AI Firewall for Conversational Applications ### Selected past work · Eight years before going independent - **Glia** — _Sr. Software Engineer_ — Led the analytics migration from **PostgreSQL to Snowflake**, coordinating across 10 teams. Built in-house Kafka tooling in Elixir. Conducted **100+ technical interviews**. - **Yolo Group** — _Payments_ — Built **crypto wallets from scratch**. Bitcoin, Ripple, Tron, Cardano. Integrated **10+ fiat payment providers**. Worked closely with Fraud and Compliance across multiple jurisdictions. - **miSalle** — _Founder_ — First production project. Reached **4% of its target user base organically in under 24 hours**. I’ve been shipping to real users since college. ## Latest writing. I publish on applied AI roughly every two weeks. Read on LinkedIn. ### [Instead of building a RAG pipeline I wrote a text file.](https://www.linkedin.com/posts/aguileraee_instead-of-building-a-rag-pipeline-i-wrote-activity-7452959456935555072-QwVb) _Apr 2026 · Essay · 6 min_ A small case study on resisting the default AI architecture. The cheapest, fastest, most reliable retrieval system for a 200-document corpus is not a vector database. It’s a prompt and a flat file. Here’s what we shipped, what we measured, and when this stops working. ## Questions I get. The five that come up on every first call. If yours isn’t here, just ask. ### Why hire you over an agency? You don’t need an agency. You need one senior engineer who ships. Agencies give you 6-week discoveries, account managers, and junior engineers doing the work. I’m one person. I write the code myself, you have my direct contact, and I start in 2–4 weeks. ### Do you have specific industry experience? If you’re fintech-adjacent, yes. I’ve shipped payments and crypto infrastructure for companies processing millions of euros across jurisdictions. If you’re in another vertical, my advantage is going deep fast. Underlying patterns translate. ### How fast can you start? Two to four weeks from a signed scope. I keep a small roster, usually 2 or 3 clients at a time, so the next slot is usually visible on the call. ### Do you work in English or Spanish? Both. If your team is bilingual, useful. If not, I adjust. ### What if my problem isn’t AI-specific? Most of what makes an AI feature ship isn’t AI-specific. Data pipelines, evals, observability, integration. If you have a hard production problem and a small team, I’m probably the right call. ## 30 minutes. Scope-shaped. Tell me what’s stuck. I’ll tell you whether it’s a one-week audit, an eight-week sprint, or a hire. If it’s the third, I’ll say so. - **Book a 30-min call:** https://cal.eu/aguilera/30min - **Email:** eduardo@aguilera.ee _Schedule a call or write first if that’s easier._ ## Links - [LinkedIn](https://www.linkedin.com/in/aguileraee/) - [GitHub](https://github.com/eaguilera23) - Email: eduardo@aguilera.ee --- © 2026 Aguilera Engineering · aguilera.ee · Based in Europe · EN / ES
