Building products
from first principles.

Rising entrepreneur and problem solver. I work across AI systems, product strategy, and backend engineering—usually at the stage where things need to be figured out from scratch.

Selected Work

Products, platforms, and systems built across marketplaces, AI infrastructure, and enterprise strategy.

Built and led a student-only marketplace shaped around trust: payments, handoffs, messaging, and the operational logic required for peer-to-peer commerce to hold together in the real world.

  • Built Stripe Connect infrastructure with 99% capture success and <0.1% dispute rate
  • Implemented real-time WebSockets for sub-second transaction and messaging updates
  • Shipped v1 from zero, launched across 2 campuses, and grew to 120 MAUs in 6 months
  • Tech: SwiftUI, Django/DRF, PostgreSQL, Redis, AWS EC2

Built an AI research and decision platform for crypto trading, unifying charting, indicator management, strategy execution, backtesting, walk-forward validation, and promotion-gate governance into a single operator workflow.

  • Best gated directional model reached 0.7472 AUC and 0.8072 sign hit rate on CLAM-gated out-of-sample evaluation
  • Improved event-detection quality to 0.7550 big-move F1 and 0.7186 recall, with OOS event AUC above 0.62 on earlier strong runs
  • Regime-aware threshold policies increased recall to 0.7757 and F1 to 0.7905 while exposing sensitivity vs. activity-control tradeoffs
  • Reduced walk-forward status payloads from ~10.8MB to ~1.6MB and scaled the platform to 20 paid users across EC2 and SageMaker

Built a production-grade AI application engine combining deterministic ranking, async job ingestion, resume tailoring, browser automation, and human-in-the-loop review into a single operating workflow.

  • Deterministic fit scoring across 6 weighted components with hard gates and reason-code explainability
  • Integrated 12 source types across modern hiring systems including Greenhouse, Lever, Ashby, Workday, and LinkedIn
  • Built cost-aware tailoring with similarity-based reuse and exact-output guardrails
  • Implemented CDP browser automation with stealth controls, challenge detection, and HITL checkpoints

Led a Walmart-sponsored product strategy initiative focused on a difficult internal question: how associate feedback becomes something trusted, legible, and actionable inside large systems.

  • Mapped breakdowns across feedback intake, context capture, prioritization, and resolution visibility
  • Identified workflow context, usability, and trust as deeper blockers than automation alone could solve
  • Produced a formal design brief and recommendation framework for internal stakeholders

Led customer discovery and product-definition work for nonprofit financial services, translating fragmented operational pain points into a clearer product and go-to-market direction.

  • Synthesized interviews into journey maps, user segments, and a dual-track MVP approach
  • Built a rules-based matching model for nonprofit finance talent
  • Shaped a Kansas City pilot GTM around education-first programming and trust-building

About

Technical product builder based in Fayetteville, AR, working at the edge of AI systems, product strategy, and software engineering—where ambiguity is high, constraints are real, and the right solution is rarely obvious at first.

A Computer Science degree at the University of Arkansas is being finished alongside the work of building real products. At Swaply, a marketplace moved from concept into a living system—trust, payments, real-time communication, and the operational logic required for people to actually depend on it.

The deeper interest is not only in building features, but in shaping the value beneath them: the invisible architecture that determines whether a product earns trust, survives contact with reality, and becomes useful in a lasting way. That thread runs through human-centered product strategy work with Walmart, nonprofit fintech design with Arvest, and AI platforms built for decision-making and automation.

The most meaningful work tends to live where the path is unclear—where technical depth and judgment matter at the same time. Problems worth pursuing are usually the ones that resist easy answers, demand patience, and reveal their structure only after sustained attention.

How I work
01

Systems over features

The deepest work begins beneath the surface—in incentives, fragility, and hidden dependencies. Products rarely fail because of one missing feature; they fail when the purpose underneath them is not fully understood.

02

Ship, then listen

Clarity is earned through contact with reality. Software becomes honest when it meets users, constraints, and consequences in the real world.

03

Depth across the stack

Work moves across User experience, backend, mobile, payments, and infrastructure to keep the whole intact. Better decisions emerge when strategy and implementation stay close to each other.

Notes

How product work is approached

Most product problems do not begin at the feature layer. They begin deeper, in the structure of the system itself. What looks like a simple interface decision is often downstream of incentives, incomplete information, trust asymmetries, operational constraints, and technical tradeoffs that quietly shape the behavior of everyone involved.

Good product work starts by making those forces visible. The goal is not to over-intellectualize the problem or delay execution, but to avoid building something polished that fails the moment it touches reality. The strongest systems usually emerge from a clear mental model first, then become sharper through direct contact with users, edge cases, and the pressure of real use.

That becomes even more important in AI systems, where the surface can appear convincing long before the underlying behavior is dependable. Demos create confidence too early. In practice, the real product is rarely just the model. It is the surrounding architecture: evaluation, orchestration, fallback paths, visibility, control, and the deliberate decision of where automation should end and human judgment should remain.

The work that feels most worthwhile tends to live in that tension. Not just making systems more capable, but making them more legible, more trustworthy, and more resilient under imperfect conditions. That is usually where the real product begins.

Currently thinking about
01

How trust systems can hold when real incentives, asymmetry, and risk begin to distort behavior in peer-to-peer markets

02

What the right abstractions are for multi-step AI workflows once orchestration, evaluation, fallback, and control all have to coexist

03

Why so many models deteriorate in production, and which evaluation patterns remain honest after the data stops being clean and static

04

How human-in-the-loop systems should feel when judgment is treated as a design constraint rather than an afterthought
