About

I build automation systems that eliminate manual effort and connect fragmented workflows. My focus is on applied AI, document intelligence, and scalable integrations — turning repetitive processes into reliable, zero-touch pipelines.

Currently studying Computer Science while applying hands-on experience across Power Platform, Python, REST API architectures, and game scripting. I care about solutions that actually ship: practical, maintainable, and measurable.

When I'm not automating enterprise workflows, I'm investigating system behavior at a low level — tracing root causes, writing reproducible fixes, and scripting game logic in Lua.

Highlight Projects

🔍 Intelligent Invoice Processing

Automated extraction pipeline for PDF invoices and NFS-e fiscal documents

Replaced a fully manual data-entry workflow with an end-to-end automation that reads, validates, and routes fiscal documents — reducing processing time and human error significantly.

Stack: Power Automate AI Builder OCR SharePoint Regex


🗄️ Centralized Storage Infrastructure

10TB network-attached storage serving heterogeneous environments

Designed and deployed a centralized storage solution supporting both Windows and Linux machines via dual-protocol sharing — consolidating scattered local storage into a single, reliable source.

Stack: Linux Windows Server SMB NFS


🤖 Productivity Bots for Microsoft Teams

Workflow automations and conversational bots for internal operations

Built a suite of bots and automated flows that handle routine team operations: notifications, approvals, status updates, and process triggers — reducing context-switching and manual coordination.

Stack: Microsoft Teams Power Platform Copilot Studio


🎮 Game Scripting & UX Systems

Lua-based gameplay logic and player experience engineering

Designed and implemented game mechanics, UI feedback loops, and player-facing systems using Lua — with a focus on responsiveness, feedback clarity, and intuitive interaction patterns. Approached game UX the same way as product UX: iterative, data-aware, and player-first.

Stack: Lua Game Engines UX Design Event-driven Architecture


🔗 REST API Integration Framework

Reusable integration layer for connecting internal systems to external APIs

Built a structured approach to API consumption: authentication flows (OAuth 2.0, API keys), error handling, retry logic, and response normalization — used as a foundation across multiple automation projects.

Stack: Python REST APIs OAuth 2.0 Webhooks Microsoft Graph


🛠️ Root Cause Investigation & System Diagnostics

Systematic debugging across OS, network, and application layers

Developed a personal methodology for diagnosing complex, non-reproducible failures — combining log analysis, behavioral tracing, and controlled testing. Focus on permanent fixes over workarounds: understanding why something breaks before touching the configuration.

Stack: Windows Internals PowerShell Linux CLI Event Viewer Wireshark


Engineering Principles

Investigate before fixing   →  Understand root cause; don't patch symptoms
Automate the second time    →  If you do it twice, it should run itself
Fail loudly, recover cleanly →  Explicit errors beat silent failures
Measure before optimizing   →  Data over intuition when performance matters
Document as you build       →  Future-you is a different person

Currently Learning

  • Lua depth — coroutines, metatables, embedding in C environments
  • Game UX — feedback design, affordance theory, playtesting methodology
  • API security — token rotation, rate limiting, secure webhook validation
  • Applied AI — document intelligence, LLM integration in automation pipelines
  • Linux administration — shell scripting, service management, networking
  • Architecture — scalable, fault-tolerant automation design

More projects and documentation coming soon.
