Full Vercel + GCP → Azure migration in one week.

US-based Y Combinator startup · Microsoft for Startups member · 2026

Problem

A YC-backed startup needed to move their entire production stack off Vercel and Google Cloud and onto Azure to unlock Microsoft for Startups credits — without disrupting customers.

Approach

Authored the migration architecture end-to-end, then orchestrated execution with Claude Code, MCP servers, and Azure Agent Dev Kit. Agents handled repo-wide refactors, infra provisioning, and contract verification while I drove design decisions and acceptance gates.

Outcome

Migration completed in 7 days from a path the founders could understand and own. Zero customer-visible downtime. Team gained an agentic operating model they continued using post-engagement.

A painting that comes alive — Junior Rodríguez × Presencia.

Junior Rodríguez (artist) · Custom brand experience via Presencia Studio · 2026

Problem

An emerging painter wanted to sell more than canvas — to give collectors a story attached to the work, and to capture the moment a viewer first meets the piece without breaking the gallery experience.

Approach

Designed an NFC-enabled painting series: the physical work, the tap interaction, and the connected digital journey behind each piece. Built the artist's catalog page, the on-tap landing, and the content flow that turns each sale into a shareable moment.

Outcome

Each painting now sells with its experience attached, not just the canvas. Collectors photograph, tap, and post the moment — turning the artwork itself into a marketing asset the artist keeps charging for.

Common questions

How does this work alongside your Microsoft role?

I take outside engagements with non-conflicting clients via Presencia Studio. Anything that overlaps with the Microsoft for Startups portfolio I either decline or route through the program itself.

Are you only for Microsoft for Startups members?

MS for Startups is the core ICP — that's where I spend most of my time and have the deepest context. I also take a small number of non-conflicting external engagements per quarter via Presencia Studio.

Confidentiality?

Standard mutual NDA on request. Nothing client-specific ever crosses into Microsoft work or vice versa.

What if my problem doesn't fit one of the packages?

Book the Architecture Review. If it's a fit, we scope a custom engagement from there. If it isn't, you still leave with a 1-page plan.
