Pentesting and offensive security
Web audits, exposure review, controlled exploitation, retesting and actionable reports for technical teams.
SaaS builder · Security Engineer · Pentester
I am Esteban Nicolás Cano. I build modern, automated and secure applications; I also find critical flaws before they reach customers, data or reputation.
Capabilities
This site is focused on concrete work: reducing risk, building maintainable products and accelerating delivery with AI without lowering the technical bar.
Web audits, exposure review, controlled exploitation, retesting and actionable reports for technical teams.
Functional prototypes, full-stack delivery, AI model workflows, automation, security, deploy and real operation.
Platform design, integrations, pipelines, cloud infrastructure, performance and maintainability from the first release.
Control validation, public surface, permissions, headers, rate limits, error handling and accidental exposure.
Products
Not slideware: real multi-tenant platforms live in production, with billing, authentication, tenant isolation and the same security discipline I apply on the offensive side.
Event venue management
Multi-tenant SaaS for event venues and planners: real-time agenda, leads, quotes, payments, contracts, staff and a client portal in one place, replacing spreadsheets and scattered chats.
Clinical photo tracking
API-first SaaS for clinical and aesthetic professionals to document visual cases: before/after comparison, clinical views, a secure patient portal, agenda, PDF export and shareable links with strong tenant isolation.
Selected work
Custom platforms delivered end to end: product decisions, architecture, security and deploy. Some client work stays unnamed by agreement.
E-commerce · professional hair care
Online store for professional hair colouring: catalogue with hundreds of shade variants, MercadoPago checkout, an automatic colour advisor that builds the full routine from real catalogue products, and an admin panel with audited stock and sales reports.
Property management platform
Platform for building and consortium administrators: expenses and settlements, payments and collections, suppliers, amenity bookings, reporting and a self-service portal for owners and tenants.
Energy · fuel logistics
Internal dispatch coordination system: it ingests operational spreadsheets, groups the work by destination and automates the messaging with each delivery point, keeping status traceability across the whole run.
