SERVICES

What I do

Serious software systems, from architecture to operational security.

I work where a simple website is not enough: software products, business platforms, hybrid infrastructure, application penetration testing, and AI automation connected to real workflows.

Software Engineering

Most software projects ship screens. I build reliable, maintainable systems built to last without depending on the developer.

Expected outcome

A reliable, maintainable software product aligned with your business processes — not a raw prototype handed over without support.

Scoping & domain modeling: precise definition of domain and business flows before writing a single line of code.

Architecture & Backend: designing APIs, database schemas, access roles, business rules, and background jobs.

Interfaces & Dashboards: building modern, responsive frontend components when the product demands them.

Cloud & Hybrid Architecture

Most cloud architectures assume guaranteed fiber and uninterrupted power. I design resilient infrastructures (AWS/Azure/Hybrid) built for real field constraints.

Expected outcome

Outage-resilient infrastructure: automated network link failover, redundant backups, and fully tested BCP/DRP.

Infrastructure & network audit: mapping hardware, remote links, workloads, data sovereignty constraints, and operational costs.

Target architecture design: integrating automatic failover, hybrid storage strategy, and pragmatic sizing.

Infrastructure as Code deployment (Terraform): infrastructure automation, backup procedures, and Disaster Recovery Plans (DRP/BCP).

Security Audit & Pentest

I assess your systems as a real attacker would. The goal is not a list of vulnerabilities — it's a clear picture of your actual risk, how it can be exploited, and where to start reducing it.

Expected outcome

A clear picture of your actual exposure: exploitable vulnerabilities, their severity and operational scope — not a raw scanner dump.

External exposure: services, interfaces and configurations visible from the Internet — IP/domain scanning, service mapping, manual exploitation of sensitive targets.

Internal systems: simulating an attacker with network access (compromised VPN, Wi-Fi, physical access) — Active Directory mapping, privilege escalation, access to sensitive data.

Web apps, REST/GraphQL APIs and mobile apps (Android/iOS): authentication flows, high-impact routes (billing, admin, export) and business logic following OWASP.

AI Automation

Your teams lose time on predictable, repetitive tasks. I integrate supervisable AI agents into your business tools to turn what slows you down into reliable workflows — without disrupting your existing organization.

Expected outcome

Manual repetitive tasks (data entry, triage, qualification, reporting) handled automatically, without losing control.

Process analysis: identifying high-ROI tasks, automation risks, and the right level of autonomy to delegate to the AI.

Agent design: tools, permissions, memory, business logic, human approval steps, and error handling.

Integration into your environment: APIs, databases, CRM, ERP, documents, or existing internal application.
