What I'm building

A current personal venture, followed by the next product direction being explored.

Private BetaPersonal Venture

Social AI

Founder / Lead Architect

AI-powered social intelligence for research, creation, and multi-channel publishing.

Social AI connects social channels to help users research trending topics, brainstorm ideas, generate content in custom brand voices, schedule, and automate publishing across platforms. Under the product workflow, PostgreSQL and Prisma support the relational data model, search, indexing, and query-heavy application flows, alongside secure authentication and compatible AI model integrations.

Selected product stories

03 / 06

Each story connects a product problem to the engineering responsibility behind its commercial release.

Shopify App / Shopify Ecosystem

Bundlefic

Dynamic product bundling and smart cart merchandising for Shopify merchants.

Commercial Release

Engineered at Themefic

Product context

Merchants need to increase average order value without complex discounting setups or invasive theme modifications that slow down storefront loading speeds.

My engineering contribution

Engineered the core product bundle mechanics, deterministic discount business rules, merchant configuration controls, and maintainable storefront cart integration.

Role

Product Engineering

Commercial product shipped at Themefic for Shopify merchants.

The complete Themefic product portfolio includes six verified commercial releases.

The operating method behind the work

How I Build

Product decisions and engineering decisions move together, from platform constraints to production feedback.

Eight stages reduce risk early, define clear boundaries, and connect launch to feedback.

Decision-to-delivery sequence

08 stages

Stage 01 of 08

Research & Constraints

Uncovering platform limits, API boundaries, and user workflows before writing code.

The question this stage answers

What are the hard platform limits, rate ceilings, and real user friction points?

Working deliverable

Constraint Analysis & Requirements Map

Applied reality

Platform app constraints shape the architecture before implementation.

Guiding mindset

Understand the environment before building the foundation.

Risk reduced before it compounds

Unsupported APIs, marketplace conflicts, and immovable rate limits.

Method, then depth

The operating sequence is supported by the architecture, systems, and platform engineering below.

Continue to Engineering Depth

Systems, platforms, and infrastructure

Engineering Depth

The technical decisions beneath reliable product software.

Engineering capability organized by system context, with tools shown as supporting evidence rather than the story itself.

Domain 01 / 07

Product Architecture & Systems Design

Designing maintainable system boundaries, domain contracts, and deterministic state flows.

Transforming complex product requirements into resilient service boundaries, clean state transitions, and auditable event flows.

Engineering focus

02 decision areas
01
Domain Decomposition & Service Boundaries

Decoupling business logic from host runtime environments, third-party quirks, and defining clear failure handling.

Patterns & technical evidence

System Topology · Bounded Contexts · Failure Handling · Modular Monoliths

02
State Machine & Lifecycle Modeling

Enforcing deterministic state transitions and pragmatic architectural contracts for orders, publications, and external syncs.

Systems, then trajectory

The journey below traces how this technical responsibility developed over time.

Continue to Builder Journey

Capability built through practice

Builder Journey

A decade of moving closer to the whole product: from interface craft, to platform systems, to end-to-end ownership.

The titles changed as the scope expanded. The throughline stayed the same: understand the problem, build the system, and stay accountable for what ships.

01 / 03

Craft

2015 – 2019

Web foundations became working software.

Responsive themes led into WordPress and WooCommerce plugin systems, where visual decisions met business logic, data, and transactional reliability.

WordPress Theme & Frontend Developer → WordPress Plugin Engineer

02 / 03

Systems

2019 – 2023

Full-Stack Software Engineer

Platform & Product Engineer

The work expanded from decoupled applications into commercial software across Shopify, Webflow, and WordPress.

Full-stack delivery became platform judgment: working within third-party runtimes, authentication models, webhooks, embedded interfaces, and marketplace constraints without losing sight of the product.

Platform Applications Engineer · React · Node.js · OAuth 2.0 · Platform APIs

Ownership

2023 – 2026

Product responsibility widened into technical leadership and venture building.

At Themefic, the role expanded into architecture, product R&D, engineering standards, platform delivery, and production infrastructure ownership across a commercial product portfolio. Building Social AI extends that product-engineering discipline into founder-level ownership.
