I'm Luis Fernandez, an electronic engineer (PUCP) specialized in software. I design and build web applications, SaaS platforms and high-performance systems, from idea to launch.
Lima, Peru · Working remotely with clients worldwide
Work
Two platforms I designed and built end to end: multi-tenant architecture, security, admin panel and public site. This is how I work with clients.
School management platform for private schools in Peru: grades aligned to the national curriculum, QR attendance, digital syllabus, official MINEDU reports and communication with families.
Online stores for small Peruvian businesses: catalog with sizes and colors, orders via WhatsApp, Yape and Plin payments, and no web design skills needed.
Services
I work with you end to end: I understand the problem, design the solution and ship it to production. No middlemen, and I choose the technology that best fits your project.
Complete platforms with accounts, roles, payments and an admin panel, ready to scale to many customers.
Software that automates your business processes: forms, reports, certificates, workflows.
C++ and parallel computing programs when speed matters, built on a solid engineering foundation.
Data modeling, secure APIs and integrations with the services you already use.
How I work
A simple, transparent process, so you always know where we are and what comes next.
You tell me what you need and what problem you want to solve. It's free and no strings attached.
I define the scope, timeline and price in writing, before starting.
I build in stages and show you progress, so we can adjust course in time.
I publish the project, show you how to use it and stay available for improvements.
I work in Spanish or English, adapted to your time zone.
About
I'm an electronic engineer from PUCP. I started with industrial automation in C++ and today I build complete web applications that run in production.
I like to understand the problem before writing code, and to deliver systems that are clear, secure and easy to maintain. I speak Spanish and advanced English.

Sienova joins “sienna”, the burnt pigment I paint with in oils, and “nova”: something new. It's how I see software: craft and novelty.
