Alexis Sanchis

Software engineer, healthcare & security

Six of my nine years in software went into healthcare and home care. I worked in the team behind a booking platform with 80,000+ users, and on offline-first apps for nurses working in areas with poor coverage. These days I build with agents, and I keep ownership of review and security.

Selected work

Opaline Santé

CBA Informatique Libérale · 2023–2025 · Team project

Problem: Let patients book home care with independent healthcare professionals (nurses, physiotherapists, etc.).
What I did: Fullstack developer in the Opaline Santé team. I also contributed to the shared UI component library with the design team. Stack: Next.js, Symfony, Laravel.
Result: The platform has 80,000+ users.

Offline-first apps for home care

Arche MC2 · 2018–2023 · Team project

Problem: Home-care services (SSIAD, SAD), nursing homes (EHPAD) and meal-delivery teams often work where the mobile network is weak or missing.
What I did: Offline-first Android apps, built as a team: an embedded SQLite database on the device, synced with the server in the background. Stack: Java and Kotlin, later Flutter.
Result: Care teams keep working without a connection, and their data syncs once the network is back.

Subscription platform for a speech therapist

Solo project

Problem: A speech therapist wanted to put her exercises online and offer them as a monthly subscription, to her patients and to anyone who wants to improve.
What I did: The whole platform, in under 24 hours of total work with agents. Stack: Next.js, Supabase, Stripe (subscriptions), Vercel.
Result: Launching soon.

Joinery application

Elipce Solutions · Team project

Problem: A complete joinery application that computes the overall performance of each product, such as Uw (thermal transmittance) and TL (light transmittance).
What I did: Built as a team: a joinery engine on the front end (React) and, on the back end (Django), an engine that computes the overall performance of each product (Uw, TL, etc.).

How I work with agents

I use agents to move faster, but I'm still responsible for what ships: architecture, tests, security and maintenance.

I build on pstack, Lauren Tan's open-source collection of skills for agents. I use an adapted version in Claude Code, with my own rules loaded in every session.

The workflow

Understand. Before touching the code, the agent explains how that part works and why it was built that way, based on the code and its history.
/how · /why
Design. Types, signatures and module boundaries are set before implementation, so the structure can still be changed cheaply.
/architect
Implement. Only what was asked, with unit tests for the happy path, edge cases and errors. No extra features, no dead code.
Verify. “It compiles” is not enough: I want to see the feature running. A bug gets reproduced first, then fixed at the root. A performance gain is measured before and after.
/bug-fix · /perf-issue · /benchmark-checklist
Review. Before merging, the agent checks what the change could break outside the diff, by running the code. I make the final call.
/blast-radius

Rules loaded in every session

Every command, flag, package and version is checked against the official docs, with a source.
What is verified, what is assumed and what is uncertain are kept separate.
Infra commands get a dry run first, and the rollback is planned before the change.
Nothing destructive or touching production happens without my confirmation.
