What I do

Services

Full ownership across the stack. Not segmented work — complete delivery.

01

Software Architecture

System design that scales. Data modeling, API contracts, microservice boundaries, and event-driven patterns — built for production from day one.

Cipher

An AI coding assistant that doesn't forget. Blockchain-backed persistent memory means context is cryptographically verifiable across sessions — not just cached. A knowledge graph structures what it learns, and QLoRA fine-tuning lets the model actually improve from experience. Built for engineers who are tired of re-explaining their codebase every session.

Cascade Inversion Cosmology

A computational research project modeling cosmic structure as self-organized criticality in a structured substrate. 1D Oslo and 2D/3D Manna sandpile simulations reproduce published critical exponents (τ≈1.55, D≈2.2) through finite-size scaling across lattice sizes — validation against the physics literature, not just plausible output. The scaling sweeps run on a self-healing AWS spot fleet: one EC2 instance per job, with spot-interruption auto-recovery, checkpoint-resume, and rsync fleet sync. Python, NumPy/SciPy, and a rigorous, documented methodology.

About

One engineer.
Complete ownership.

Staff Solutions LLC is a software engineering consultancy built around one principle: full-stack accountability. No segmented work. No handoffs. One owner, start to finish.

Deep experience across Go, Python, React, AWS, and distributed systems — including patent-pending IAM architecture and production AI integrations. I take projects from whiteboard to working, tested system in production.

Whether it's implementing UI from Figma designs, wiring up a serverless AWS backend, designing a DynamoDB schema, or standing up CI/CD from scratch — I own the whole thing.

Current availability

Accepting new consulting engagements. Available for full-lifecycle ownership of greenfield builds and complex migrations.
