PUBLIC PORTFOLIO / 2026

Systems
that hold.

I build systems that hold under pressure — from major incidents and service workflows to full-stack platforms and open-source tooling. Ambiguous constraints in; software that ships, and stays operable, out.

01

The work, entered in full.

THREE SYSTEMS · ONE OPERATING INSTINCT

Product & technical ownership · 2023—present

Taking a platform from roadmap to real scale

As founding CTO, I own the path from technical direction through architecture, web and mobile delivery, cross-functional decisions, vendors, and team development.

Evidence boundary · Operator-approved production aggregates · July 2026

CONSTRAINT
A growing commercial product needed one technical system across product, delivery, and operation.
DECISION
Keep architecture close to product reality and own the critical path end to end.
OUTCOME
Current aggregates record 12,000+ monthly active customers, 17,000+ unique paying customers, and more than $15M in completed customer deposits.

Protocol & application engineering · 2022—2024

Shipping audited systems across protocol boundaries

At Humans.ai, I designed and shipped smart contracts and applications across Ethereum, Hedera, and Evmos, joining front end, back end, and protocol concerns.

Evidence boundary · Career evidence · current CV

CONSTRAINT
Protocol work couples product behavior to irreversible, adversarial infrastructure.
DECISION
Treat integration, auditability, and operational correctness as one delivery problem.
OUTCOME
Production work included internal and external audit flows; the current CV records $1M+ TVL.

Operations & service systems · 2015—2022

Turning operational pressure into repeatable control

Seven years across support, major incidents, enterprise service platforms, vulnerability remediation, reporting, and workflow automation shaped how I build today.

Evidence boundary · Career evidence · current CV

CONSTRAINT
High-impact systems fail across people, process, communication, and software—not inside one neat layer.
DECISION
Make ownership, state, evidence, and recovery paths explicit before optimizing throughput.
OUTCOME
Led incident coordination and built service workflows, dashboards, automations, and remediation processes for enterprise environments.

PUBLIC MERGE RECORD — NOT A STREAK QUOTA

Operating method

Judgment first.
Leverage second.

  1. 01Clarify

    Find the real constraint and define an observable finish line.

  2. 02Model

    Map ownership, failure paths, trade-offs, and the smallest useful system.

  3. 03Build

    Ship an end-to-end slice that can be tested in reality.

  4. 04Operate

    Instrument the seams, reconcile effects, and make recovery routine.

  5. 05Compound

    Turn repeated judgment into tooling, automation, and reusable systems.

AI is part of the toolchain. Judgment, accountability, and the final call stay human.

03

The through-line is operational.

2015—2021

Operate

Support, major incidents, and infrastructure risk

Learned production reality through support engineering, incident leadership, vulnerability remediation, and enterprise operations.

2021—2024

Build

Platforms, workflows, applications, and protocols

Moved deeper into ServiceNow systems, full-stack product delivery, and production blockchain engineering.

2023—now

Compound

Founder ownership and leverage systems

Owns technical direction and delivery while turning repeated work into reusable workflows, tooling, and AI-assisted operating systems.
