Journey deeper

↓

Foundations in Faith

I build with care. Faith, marriage, and fatherhood ground a practice of stewardship—patient, respectful, and honest. I design systems that endure: clear interfaces, sound architecture, and tools that serve people well over time.

Technology should help. I combine curiosity with clarity to make simple, useful products.

Digital Mastery

I ship full‑stack products: fast frontends, reliable services, and clean, scalable cloud foundations.

I build AI‑enabled web systems with local and cloud inference. Ollama for local models, Vercel AI SDK and OpenAI API for hosted inference, and LangChain for orchestration when needed—always with clear architecture and responsible usage.

Human judgment with AI acceleration helps me move quickly without sacrificing quality.

Engineering Journey

Startups demand focus: ship, learn, adjust.

I decide with incomplete information, prioritize essentials, and iterate toward what users need.

The goal is steady progress and sustainable momentum.

Intentional Architecture

Every line has a purpose. Components tell a clear story. Systems reflect values.

Sustainable Engineering

Building for longevity, maintainability, and growth. Creating systems that evolve gracefully with changing needs.

Human-Centered Design

Technology in service of humanity. Interfaces that feel natural. Experiences that bring joy and efficiency.

Research

Exploring security, identity, and human‑centered AI. Work spans formal analysis, applied systems, and public health forecasting.

Publications

Novel Extended Federated Authentication & Authorization Framework

A session-less extension to OAuth 2.0 that addresses token confidentiality during transit and simplifies the login flow without third‑party intermediaries. The model secures initial credential exchange over HTTP through client‑side encryption and server‑side decryption, and eliminates redirection by deploying dedicated authorization servers. Validated in a Writing Center application, with recommendations for formal standardization and cross‑environment testing.

View on Semantic Scholar

OAuth tokens risk exposure during transit. While request integrity can be verified, confidentiality of token exchanges is not guaranteed across implementations.

Eco‑Epidemiological Forecasting

Upcoming

Ongoing independent research with Victoria Festus (Public Health) on a spatiotemporal deep learning system to anticipate climate‑driven vector‑borne disease outbreaks in rapidly urbanizing Global South regions.

Fuses satellite imagery, climate signals, and epidemiological records to produce neighborhood‑level risk forecasts with short lead times.

Expected Impact

Enable precision public health through early, targeted interventions.
Reduce intervention costs by focusing resources on high‑risk zones.
Strengthen climate resilience in fast‑growing urban environments.

Autopoietic Resilience

Upcoming Featured Independent

Independent research exploring a multi‑agent reinforcement learning approach to discover novel, non‑analogous adaptation metrics in a climate digital twin—letting agents surface signals humans might miss.

Expected Impact

Earlier tipping‑point detection through emergent metrics.
Reduced expert bias via unsupervised agent discovery.
Safety insights for public health in extreme urban climates.

Form as Conversation

Design is a conversation with the user. Simple feels kind.

Interfaces should feel obvious, calm, and friendly.

Form supports function, and function serves people.

Beauty supports function. Animations and transitions are purposeful, and color helps the user—never distracts.

Cosmic Minimalism

Only what matters, nothing extra.

Atmospheric Depth

Layers that reveal themselves gently.

Sacred Proportions

Shapes and rhythms that feel right.

Constellation of Impact

I’ve built systems for education, finance, and healthcare—dependable tools that help people every day.

They’re not case studies—they’re products that keep serving as needs grow.
