Software Engineering
Backend applications, APIs, internal tools, client-facing systems, validation, testing, and maintainable application structure.
Software Engineering · Systems Architecture
I build the systems behind the operation.
Software, APIs, automation, infrastructure, data systems, and AI-assisted applications — designed as maintainable systems rather than disconnected technical tasks.
Python
FastAPI
PostgreSQL
TypeScript
Docker
Linux
APIs
AI / LLM
Technical capability
Working across the full system.
My work spans application development, architecture, infrastructure, automation, data, security controls, and AI integration. The goal is to understand how the pieces interact and build them as one reliable operating system.
Systems Architecture
Application boundaries, database design, service integration, deployment architecture, reliability, and technical decision-making.
Automation & Integration
Workflow automation, API integrations, document pipelines, notifications, task routing, and systems that move information automatically.
Infrastructure
Linux environments, Docker, deployment, networking, Cloudflare, environment management, operational controls, and reproducible systems.
AI Engineering
LLM integration, agents, structured inputs and outputs, model-assisted workflows, validation layers, and controlled AI use inside larger systems.
Security & Data
RBAC, tenant isolation, scoped access, audit trails, secrets hygiene, structured data capture, search, reporting, and evidence-backed workflows.
Selected systems
Current engineering work.
Most active application code is private. These summaries show the engineering problems, architecture, and capabilities without exposing production or client implementations.
Private system
Secure multi-tenant application platform
Business workflow and document infrastructure
FastAPI and PostgreSQL application architecture with authentication, RBAC, tenant boundaries, auditability, document workflows, structured intake, and role-specific operations.
Private system
Financial technology
FXate / BOSBOX
Local market-monitoring and decision-support infrastructure using live market data, structural event detection, lifecycle alerts, deterministic rules, and AI-assisted reasoning.
Workflow system
Business automation
Intake-to-document workflows
Systems that turn incoming forms into structured records, generated documents, notifications, assignments, and tracked workflow steps.
Architecture
AI systems & automation
Agent and integration architecture
Reusable application patterns for AI-assisted systems, APIs, automation, tool integration, structured outputs, and controlled model use.
Technical stack
Tools selected around the problem.
The stack changes when the problem requires it. These are the technologies and disciplines I work with most often.
Application core
Python · FastAPI · REST APIs · typed services · validation · testing
Persistent systems
PostgreSQL · relational modeling · migrations · tenant-scoped access · structured data
Interfaces
JavaScript · TypeScript · Vite · HTML · CSS · API-integrated clients
Runtime
Linux · Docker · Cloudflare · networking · deployment · configuration discipline
Assisted systems
LLM APIs · agents · structured prompting · workflow automation · external integrations
Reliability
RBAC · tenant isolation · audit · pytest · Ruff · mypy · Git · observability fundamentals
Engineering approach
Build for operation.
Not just demonstration.
I prefer explicit architecture, controlled boundaries, small verifiable changes, and systems that another developer can understand and operate.
Correctness first
Typing, validation, tests, clear contracts, safe defaults, and explicit failure behavior.
Security by design
Least privilege, scoped access, secrets hygiene, auditability, and isolation designed into the architecture.
Maintainable systems
Modular code, documented decisions, disciplined Git workflows, reproducible environments, and clean handoffs.
