AI Product Engineering
LLM workflows, AI-assisted tools, MCP integrations, local model experiments, custom memory concepts, and reasoning systems.
Available for full-time and contract roles
AI-focused full-stack engineer building systems that think, ship, and scale.
I am Pedro "Axefield" de Castro Davila, a TypeScript-first systems builder connecting LLM tooling, Node.js platforms, automation workflows, dashboards, UX-centered interfaces, and creative technology into usable products.

What I build
Practical systems across AI, product engineering, UX, and creative technology.
The through-line is turning ambiguous technical possibilities into working interfaces, workflows, and platforms.
Full-Stack Development
TypeScript, Node.js, Express services, REST APIs, dashboards, frontend interfaces, auth flows, and SaaS-style tools.
UX Engineering
User flows, interface clarity, design implementation, conversion paths, performance, accessibility, and product polish.
Automation And Data Systems
Workflow automation, trading dashboard concepts, data pipelines, signal surfaces, internal tools, and operational systems.
Creative Technology
Unreal Engine experiments, interactive worlds, narrative IP systems, AI media generation, and game-adjacent production tools.
Platform Operations
WordPress, Shopify, CMS/CRM/SaaS management, technical SEO, page speed, backups, integrations, and client-ready delivery.
Proof map
Work organized as systems, not buzzwords.
Each case study is framed so a hiring team can see the problem, architecture, tradeoffs, quality bar, deployment path, and product value behind the code.
Platform
Truligon
Self-directed AI/product engineering lab covering subdomain apps, auth, dashboards, email systems, learning modules, and UX architecture.
C++ AI systemsMythogon
CMake-based C++ decision/inference system with mythic headers, server components, protobuf/gRPC examples, shaders, and AI orchestration design.
AI systemsLLM Tooling And MCP
Model Context Protocol integrations, local LLM workflows, reasoning tools, Cursor/Claude/ChatGPT workflows, and fine-tuning exploration.
AutomationFintech Dashboards
Personal trading dashboard concepts, signal workflows, market analysis surfaces, and automation systems for decision support.
Creative techInteractive Worlds
Game-adjacent systems, Unreal Engine exploration, narrative IP, AI-assisted media workflows, and worldbuilding tools.
Engineering evidence
Hands-on coding tied to systems, reliability, and product outcomes.
I want interviewers to find the concrete work quickly: languages mapped to systems, systems mapped to technical problems, and technical problems mapped to delivery outcomes.
TypeScript / Node.js
Built the Truligon platform surface: Express routing, subdomain handling, admin/auth flows, dashboard concepts, Vite build outputs, and production-facing static delivery.
Python Automation
Used Python for Mythogon configuration, research, PDF/protection utilities, and AI workflow support where repeatable scripts reduce manual setup and validation work.
SQL And Data Systems
Worked with Prisma, SQLite, schema-backed services, dashboard data concepts, and reasoning or memory stores that need clear data boundaries and maintainable access paths.
C++ Systems
Developed Mythogon as a CMake-based C++ system with decision-engine headers, server modules, protobuf/gRPC examples, shader experiments, and performance-oriented architecture notes.
Quality And Testing
Use TypeScript checks, frontend builds, generated-page parse fixes, accessibility scans, code review habits, and explicit route verification to keep changes maintainable.
Reliability And Deployment
Maintain Cloudflare tunnel routing, subdomain configs, static asset paths, canonical pages, and production recovery steps so shipped surfaces stay reachable and debuggable.
Company fit
Where I create leverage.
AI product teams
I can connect LLM capabilities to usable product surfaces, tool workflows, and internal automation.
SaaS and startups
I can prototype across frontend, backend, APIs, dashboards, onboarding flows, and product UX without waiting on perfect specs.
Agencies and ecommerce
I bring practical delivery experience across WordPress, Shopify, technical SEO, page speed, CMS operations, and client-facing UX.
Game and creative tech studios
I bridge systems design, AI tools, Unreal workflows, storytelling, interactive media, and production tooling.
Hiring packet
Resume, proof, and contact are all one click away.
I am currently focused on roles in AI engineering, full-stack TypeScript development, LLM tooling, UX engineering, automation, and creative technology.
