01 / ABOUT
Built for the space between software and operations.
My work centers on systems where reliability matters: payment flows, transaction investigation, settlement processes, database-heavy applications, and the tools teams use to operate them every day.
I combine backend logic, SQL, automation, and interface design to make technical workflows easier to understand and faster to use. The goal is practical software: clear states, fewer repetitive steps, and better visibility when something needs attention.
02 / SELECTED WORK
Systems that make operations easier to run.
A portfolio view of the kinds of engineering problems I work on across payments, automation, and data.
02
AUTOMATION
Settlement & Reconciliation Automation
Automation workflows designed around settlement checks, reconciliation, exception handling, and clear operational alerts.

DATA & MONITORING
Transaction Intelligence
Database-driven monitoring patterns for investigating transaction flows, validating states, and turning operational data into actionable views.

03 / DISTRIBUTED HONEYPOT LAB
One observation is a signal. Independent agreement is evidence.
A portfolio-safe simulation of a distributed deception network. Sensors sign what they observe; the correlation layer rewards independent network agreement instead of trusting a single source.
Sensor federation
10 independent demo nodes · signed telemetry · no live attack traffic

correlated source
Hover nodes to inspect independent network labels.
Signed at the edge
Each sensor signs its own normalized observation before it enters the federation.
Independent agreement
Correlation rewards observations from distinct networks so one compromised source cannot dominate confidence.
Auditable evidence
The website demo models an append-only event trail that can later be backed by a ledger or transparency log.
04 / CAPABILITIES
A practical full-stack toolkit.
Backend logic, data, automation, and interface work brought together around real operational needs.
Application Engineering
Modern internal tools and web applications with clear flows, maintainable code, and performance-conscious interfaces.
Next.js & ReactPython & FlaskREST integrations
Data & Database Work
Practical SQL for transaction-heavy systems—from investigation queries to reporting and performance-minded data access.
