Engineering Track Record
15+ years of engineering across regulated environments, from mission-critical enterprise systems to the platforms and intelligence initiatives I build today.
MARKET PAIN INTELLIGENCE
AI-powered market intelligence platform that surfaces recurring business problems and emerging opportunities from real-world professional demand. MPI transforms fragmented market signals into structured intelligence, helping founders, product teams, and business leaders identify recurring problems, underserved markets, and opportunities worth pursuing.

CYBERSECURITY PAIN INTELLIGENCE
Cybersecurity intelligence and research initiative focused on the practical realities of modern security. CPI combines technical research, hands-on security work, and structured analysis to examine how vulnerabilities, misconfigurations, exposed infrastructure, human behavior, and other weaknesses connect to create meaningful security risk.

BRIEF SYNTHESIS
AI-powered project intelligence platform that transforms project briefs into structured intelligence, risk assessment, execution strategy, and engagement proposals. It helps teams understand project context, expose hidden constraints and risks, define validation paths, and communicate recommendations before committing engineering resources.
Technical execution logs across regulated sectors
TELECOM OPERATIONS — 2 YEARS
High-volume subscription and provisioning systems where billing accuracy and revenue continuity are non-negotiable.
• Manual subscription workflows and payment fragmentation → Integrated recurring billing with standardized C# business logic and third-party gateway automation → Eliminated reconciliation gaps and ensured consistent revenue cycles.
• Inconsistent legacy UI across modules → Standardized interface using a reusable component framework with strict multi-tier separation → Accelerated delivery, reduced technical debt, and unified enterprise user experience.
• High-volume billing operations prone to data drift → Enforced controlled SQL stored procedures with multi-step validation and automated invoice generation → Maintained transactional integrity across peak loads and delivered audit-ready financial outputs.
Tech: ASP.NET Web Forms, SQL Server, DevExpress, Payment Gateway APIs, Visual Studio
Standards: Revenue-critical uptime, multi-tier architecture, component-driven UI, strict data validation
INSURANCE & CLAIMS SYSTEMS — 1 YEAR
Regulated enterprise platforms handling policy lifecycles, carrier integrations, and compliance-driven workflows. Focus on system modeling, process traceability, and technical-business alignment.
• Fragmented business processes and unclear system boundaries → Mapped end-to-end workflows using UML (activity, sequence, class diagrams) and reverse-engineered legacy behavior → Delivered clear architectural blueprints, aligned stakeholders, and established compliance-ready traceability.
• Unstructured operational handoffs and audit gaps → Documented as-is processes, mapped cross-module data flows, and defined state-transition rules → Reduced integration friction, enabled predictable carrier reconciliation, and created a documentation baseline for future system evolution.
• Stakeholder misalignment on system capabilities → Facilitated collaborative modeling sessions, standardized documentation artifacts, and enforced version-controlled workflows → Ensured shared technical understanding, accelerated requirement validation, and established practices that scaled into later architectural leadership.
Tech: J2EE, JSP, Relational Databases, Enterprise Architect (UML), Visual SourceSafe
Standards: Regulated process traceability, audit-ready documentation, multi-tier separation of concerns, version-controlled environments
Current Initiatives
HEALTHCARE PLATFORMS — 11+ YEARS
Mission-critical systems handling beneficiary records, exams, and hospitalizations. Zero tolerance for downtime or data exposure.
• Monolithic legacy stack (ASP Classic, WebForms, Delphi) causing maintenance debt → Refactored with SOLID/design patterns, then rebuilt core platform using DDD and Clean Architecture with decoupled WebAPI → Extended legacy lifespan during transition, enabled independent dev cycles, and eliminated structural bottlenecks without business interruption.
• Initial pentest exposed critical vulnerabilities (plaintext credentials, SQLi, weak session validation) → Implemented comprehensive remediation: parameterized queries, strict CORS, PGP 4096-bit encryption, RBAC + policy-based access, and immutable audit trails → Zero successful breaches in subsequent annual pentests; passed ISO 27001, LGPD, and GDPR audits without emergency patches.
• Fragmented operator layouts and manual data imports causing billing errors → Standardized ingestion via unified JSON schema, automated TISS-XML billing generation, and enforced data anonymization for non-production environments → Eliminated manual import failures, ensured cross-system data consistency, and maintained compliance-ready pipelines.
Tech: C#, .NET Core, ASP.NET WebAPI, SQL Server, Azure DevOps, React, Bootstrap, PGP, Azure WAF
Audited against: ISO 27001, LGPD, GDPR, TISS-XML, ANS, Enterprise security standards
