ConstructAI (Austin, TX) turns 2D construction drawings into native Revit BIM models with quantity takeoffs included: modeling work that used to take about 3 weeks now ships in roughly 3 days. As VP of Software Engineering I lead the product’s architecture and development — backend, infrastructure, deployments, and billing — with a compact team of 3 engineers, proof that you don’t need a large team to sustain a complex product.

Responsibilities: designing the microservices architecture, building the platform’s core features, managing cloud infrastructure and deployments, integrating payments and subscriptions with Stripe, and training the team in AI-assisted development and solid engineering practices.

Key Achievements: built Workspaces, the drawing extraction and validation platform with vector annotation tools (grids, columns, and structural elements layered over the PDF); created AI services with FastAPI + LangChain on top of Gemini and Claude models to process construction drawings; implemented a multimodal RAG system with PostgreSQL + pgvector, hybrid search (semantic + full-text), and a retrieval graph orchestrated with LangGraph; and shipped a conversational Copilot built on the Claude Agent SDK and wired into Revit through MCP.

Shoppy.chat delivers AI-powered smart avatars that work 24/7 to drive sales: assistants that understand the business from day one and answer customers instantly, accurately, and with a human touch. As CTO and Co-Founder I lead the platform’s product and technology.

Responsibilities: integrating OpenAI models with an advanced system for creating and managing per-business custom prompts, designing the microservices architecture (web scraping to expand each agent’s knowledge, plus Tool management), and configuring and deploying cloud infrastructure on VPS across Azure and GCP.

Key Achievements: built interactive 3D avatars with synchronized voice and motion; implemented a RAG system with vector databases to process documents and enrich agent context and accuracy; delivered a centralized admin panel with conversation analytics and efficiency reporting; and enabled multichannel communication across Web Chat and WhatsApp.

I led the design and development of an advanced Virtual Assistant powered by Generative AI to improve communication and support for TEDI’s customers and students. The goal was to raise service quality while taking operational load off the internal teams.

Responsibilities: building a microservices solution with FastAPI and LangGraph (Agent Supervisor) to orchestrate complex AI agents on top of PostgreSQL, implementing a RAG system to vectorize the internal database and tailor answers to each student’s profile and resources, engineering multi-agent prompts to deliver high performance at a low operating cost, and designing a conversation Admin Panel with alerts for human handoff to the sales team.

Key Achievements: the assistant has been in production for over a year and has handled more than 40,000 conversations and nearly 300,000 messages, resolving over 90% without human intervention and steadily lightening the load on the sales and customer support teams. Later, as a freelance consultant, I built EDI, the internal Intelligent Academic Assistant for students: an agent with RAG over the transcripts of every course video — more than 360 courses and 4,000 videos vectorized with pgvector — that answers questions citing the exact timestamp of the source, recommends courses, and connects content across the student’s entire learning path.

GoJom was Latin America’s first intelligent real estate portal, a proptech “one-stop-shop” that grew to operate in Peru, Ecuador, Colombia, and Mexico with more than 200 employees. As CTO and Co-Founder I built the product and led a team of 8 developers — the largest I have ever led — keeping it deliberately compact and focused. The company was selected by Y Combinator (W22) and closed a US$1M pre-Series A round in December 2021, at twice its target.

Responsibilities: recruiting, hiring, and leading the tech team, defining the cloud architecture, prioritizing and shipping features to production, ongoing mentorship, and hands-on development of the platform’s critical components.

Key Achievements: a real estate analytics engine that processed more than 386,000 properties in Colombia and 369,000 in Peru, publishing the listings that sustained average growth of nearly 100% month over month in sales for four straight months, with properties selling in under 7 days. Entering Mexico was the team’s toughest scalability challenge: nearly 3.5 million properties, a market almost ten times larger than the previous ones, which forced us to rethink the indexing and processing architecture to support it. I also launched the region’s first intelligent search engine for the sector, built on ElasticSearch/OpenSearch for real-time market comparables, the first AI agent for Latin American real estate, and a dedicated SaaS for real estate agents. The AWS architecture let us open a new country in a matter of weeks.

Maintained the platform, helped recruit the new tech team, and advised on and scoped new features.

As CTO I led technology and a team of 5 through Turismoi’s expansion into Spain, Colombia, Ecuador, and Chile, with more than 50 tour operators per country. The company won the Premio Creatividad Empresarial 2019 (UPC’s national business creativity award) in the Tourism and Recreation category along with recognition from Startup Perú, and went on to raise US$3M backed by Axon Partners Group.

Signature achievement: re-engineering each country’s portal — until then independent — to consolidate the entire tour catalog into a single regional marketplace, with a unified tour repository exposed via API to global channels like Viator, Musement, and Civitatis. That shift turned a collection of local sites into one distributable platform.

Responsibilities: a Global API for the entire country network (Ruby on Rails + JSON API), integrated into Peru.com, Adonde.com, and Deambula.com; ElasticSearch-powered search; a tour booking system with online payments (Culqi, PagoEfectivo, PayU, MercadoPago, PayPal, and Stripe); and SaaS and widgets for the reseller network, with custom wildcard subdomains.

I built Turismoi’s MVP from scratch and laid the foundations the company would grow on for the next decade: a tours and activities marketplace that boosts domestic tourism, gives local operators digital distribution, and builds a community of travelers across Latin America and Spain.

We launched first in the Peruvian market (2013) and, because the architecture was designed to be multi-country from day one, expanding across the region required no product rewrite. That foundational work is exactly what later allowed me, as CTO, to unify the entire network into a single regional marketplace.

Responsibilities: designing the data model and product architecture, building the core of the web and mobile platform, and a Google Maps geolocation system that links nearby places to recommend tours close to the traveler.

E-Holding was the company behind the most complex projects of that era — AdondeVivir and PeruAutos among them — and where I took on my first leadership role: heading the development area and coordinating the teams that built every portal in the group.

Responsibilities: directing the web development teams, organizing and prioritizing the group’s projects, introducing version control and agile methodologies as standard practice, driving SEO strategy across all portals, and administering the company’s servers. Beyond the management role, I kept coding on the projects — a constant throughout my career.

We shipped the PeruAutos MVP — a marketplace for buying and selling cars — to production in under two months with a team of just two developers: me on the backend and a frontend developer who, more than a decade later, would become my co-founder at Shoppy. It was my first proof that a small, focused team beats a large, scattered one — a conviction that has stayed with me ever since.

Responsibilities: project planning, database design, development of every module in the portal, SEO strategy for organic ranking, and management of online service orders.

I was part of the founding technical team — 4 developers — that built AdondeVivir from scratch into Peru’s leading real estate portal by inventory, overtaking Urbania. According to the owner’s media kit, the platform reached 1.75M visits and 195,000 leads per month. It was acquired by Navent (Tiger Global’s classifieds group) and years later became part of the portfolio bought by QuintoAndar, the Brazilian unicorn.

Responsibilities: initial project planning, database design, building the modules in Ruby on Rails, SEO strategy to rank the portal, integrating Safetypay as the payment gateway, and management of online service orders.

Adonde.com was Peru’s first web search engine and directory, online since 1997. This is where it all started: I joined as a developer, and the quality of my work opened the doors to AdondeVivir and Turismoi, both founded by the same entrepreneur.

Responsibilities: building the search engine and its relevance algorithms, normalizing the existing databases, SEO strategy — including web server configuration for friendly URLs — that lifted the ranking of both the search engine and the schools directory, a local news and newspapers system built on Ruby on Rails with its own API, the Diarios Perú mobile app, and a new custom CMS.
