I build and stabilize the software your business runs on — then hand you the keys.
A single senior engineer embedded with your team for 4–6 months: architecture, AI and automation features, payments, and the reliability practices to keep it running after I leave. No agency layer, no junior bench.
From first conversation to final handover
A defined process, so you always know what phase we're in, what it costs, and what happens if you need changes after delivery.
Discovery
Meetings & interviewsI meet with you and whoever else is involved in the solution — the people who'll actually use or run it — to understand how the business operates today and what it really needs.
Proposal
Written scope & pricingYou get a written project proposal with a few budget options to choose from. You approve it as-is or ask for changes before anything is scheduled.
Agreement & payment terms
Before work startsOnce you decide to move forward, we agree on how the project is paid: an upfront deposit plus installments, or fixed monthly payments for the length of the engagement.
Build, launch & review
The bulk of the engagementThe solution is built, delivered, and put into production. I do the work myself; on projects with tight deadlines I can bring in trusted contractors for specific pieces, always under my direct oversight. Once it's running, we gather feedback, test it under real use, and collect the changes that come out of that round.
Final delivery
Close of engagementThose adjustments are made and delivered as the final version of the project. Anything requested after that point is treated as ongoing maintenance or a new, separate project.
Four things businesses usually need from this kind of engagement
Platform architecture & build
Backend, APIs, and admin/customer-facing dashboards designed to be extended by whoever owns the codebase next — not a personal framework only I understand.
AI & automation integration
LLM-backed chat and search features, document processing, and workflow automation (N8N) wired into tools your team already uses, scoped to what actually reduces manual work.
Payments & auth
Stripe billing and payment links, passwordless and social login, subscription access — the plumbing most platforms need but nobody wants to own.
Cloud reliability & DevOps
Infrastructure as code (Terraform), CI/CD pipelines, monitoring and alerting — the practice of keeping a system healthy, drawn from working as a Site Reliability Engineer, not just deploying and hoping.
Platforms I've designed, built, and operated
A sample of engagements across nonprofit, marketplace, and enterprise settings.
Cloud-native AI platform for human rights research
IT Solutions Architect / Technical Lead — International Institute for Social Responsibility and Human Rights (IIRESODH)Directed and built an electronic research platform used by human rights defenders to search and validate case law across UN, Inter-American, and other international systems — replacing manual document review with AI-assisted search.
- Backend, REST API, and an internal admin dashboard for managing documents, links, and case data
- Client-facing UI: document search, a chatbot backed by ChatGPT/Gemini, case profiles, and flowcharts
- Stripe subscription billing with webhook-driven access control; passwordless and social login
- Deployed and operated on a VPS via Coolify and Portainer, with DNS and subdomain routing for multiple apps
- N8N workflows connecting the platform to Google Workspace and internal databases
Multi-cloud marketplace integrations
Technical Lead, Systems Integration — IBM / KyndrylLed the effort to bring IBM and Kyndryl's internal automation tools onto the self-service multi-cloud marketplace, turning architecture requirements into shipped modules used well beyond the original team.
- Designed APIs and a service roadmap, starting with UMA and POWER VM integrations
- Built an event-driven backend with RabbitMQ message queuing and Kubernetes for scale
- Coordinated architectural review across squads; tools reached adoption among multiple Fortune 500 customers
AI-assisted vehicle marketplace
Full-stack developer — Trekko (trekko.cr)Built a car-listing platform that identifies a vehicle's make, model, and features from photos, and surfaces fuel-efficiency and cost estimates to buyers.
- Admin dashboard for platform owners: listings, user and dealer management, traffic data
- Seller dashboard for creating and managing listings and pricing
Open-source e-invoicing library
Independent — used in production POS systemsBuilt and open-sourced a C# .NET library that handles the XML digital-signature and API requirements for Costa Rica's electronic invoicing system, later integrated into point-of-sale software for a retail store and a restaurant.
Stack & day job
Alongside consulting, I work as a Site Reliability Engineer on IBM's Security Verify SRE team — the reliability half of this offering isn't theoretical, it's what I do daily.
Who you'd be working with
I'm a software engineer and IT consultant based in San José, Costa Rica — dual Costa Rican and Italian national, which in practice means I work comfortably across both Americas and European business hours.
I graduated with honors in Computer Science & Multimedia Technology from the University of Costa Rica, and have spent the years since moving between building things (platforms, APIs, developer tools) and keeping them running (as a Technical Lead at IBM/Kyndryl, and now as an SRE). A side project of mine, a VS Code extension called Line Highlight Bookmark, has been downloaded more than 9,000 times — a small proof that I care about shipping things other people actually use.
Consulting engagements sit alongside my full-time SRE role, which is exactly why they're structured the way they are: scoped, time-boxed, and built to leave your team self-sufficient rather than dependent on me.
