Frontend engineer building SaaS, AI-native tools and experimental systems.

I work at the intersection of interface engineering, product thinking and weird technical experiments, from fintech flows and design systems to open-source mods, AI agents and bootstrapped SaaS.

Operating Domains

The portfolio is organized like a system map: professional interface work, open lab experiments, SaaS operations and AI tooling.

FIN-UX

Fintech flows

Authorization, simulation, documents and contract journeys with real business rules.

AI-IO

AI-native tools

Interfaces for agent presence, workflow coordination and local-first automation.

OPS-SYS

SaaS operations

Products shaped by payments, field constraints, support paths and repeatable systems.

OPEN-LAB

Experimental systems

Mods, shells, media workflows and technical prototypes built as learning engines.

Manifesto

This site is a living archive of things I build, study and prototype. Some projects are professional case studies. Some are open-source experiments. Some are early SaaS ideas. The common thread is systems thinking: interfaces, workflows, technical constraints and products that need to survive real users.

Builds

Proof of work across product, systems and interface complexity.

Selected professional cases, SaaS concepts and experiments. Confidential work is represented with abstract technical diagrams instead of real client screenshots.

Looking for a frontend engineer who can think beyond the ticket?

I build interfaces with product context, technical discipline and a strong sense of how systems behave in the real world.
