AI Automation | Full-Stack Development | API Integration | Business Systems

I build practical software around real business workflows — combining software engineering with 13 years of international trade and manufacturing operations experience and 5+ years of programming experience.

My focus is not only writing code, but turning operational requirements into systems that are testable, auditable, maintainable, and useful in day-to-day work.

AI SaaS Integration Lab	Operations Reconciliation Toolkit	Business Operations Mini Platform

A GitHub-native Action that deterministically checks whether a repository contains the evidence needed for client, developer, or operations handoff. It runs without an LLM or hosted backend, produces explainable readiness results, and is released as v1.1.0 on the GitHub Marketplace with a maintained v1 major tag. Its v1.1.0 workflow-security checks are enabled across four public dogfood repositories, including explicit workflow permissions and immutable external Action refs.

Stack: TypeScript, Node.js 24, GitHub Actions, YAML, @actions/core, ncc

A synthetic API rescue case study that reproduces duplicate-delivery, concurrency, retry, timeout, transaction, and error-leakage failures, then repairs them with boundary validation, durable SQLite claims, business-level idempotency, bounded transient retries, transactional completion, and explicit production limitations.

Stack: TypeScript, Node.js 24, Express, SQLite, Zod, Vitest, GitHub Actions

A full-stack AI integration project demonstrating a support workflow with structured AI output, provider abstraction, bounded retry/timeout behavior, human approval, SQLite persistence, audit history, automated tests, and browser E2E verification.

Stack: TypeScript, React, Vite, Express, SQLite, Zod, Vitest, Playwright

A deterministic reconciliation toolkit for matching orders and payments, identifying explainable anomalies, preserving audit history, and exporting reviewable reports.

Stack: .NET 10, ASP.NET Core, SQLite, C#, Playwright

A business operations platform covering purchasing, receiving, inventory ledger, sales fulfillment, workflow controls, transactions, auditability, schema migrations, API validation, and browser E2E testing.

Stack: Java 25, Spring Boot, JDBC, Flyway, H2, Maven, Playwright

• AI and workflow automation
• Full-stack and backend development
• API and SaaS integrations
• Business systems, ERP-style tools, and internal operations software
• Data processing, reconciliation, and audit workflows
• Code rescue, maintenance, and reliability improvement
• Agent / MCP / developer workflow integrations

I am especially suited to small and medium-sized delivery scopes where the client needs a clear result rather than a large consulting process:

• AI automation & integration — connect AI models, APIs, SaaS tools, internal workflows, approval steps, and audit trails.
• AI-generated / vibe-coded app rescue — diagnose bugs, repair unreliable code, add tests, stabilize APIs, improve error handling, and get CI green.
• API & webhook reliability — idempotency, retries, timeouts, validation, concurrency safety, transaction boundaries, and error hygiene.
• Small full-stack business tools — internal dashboards, admin apps, operational workflows, CRUD/API systems, and lightweight business platforms.
• Data reconciliation & reporting — match data across systems, identify anomalies, create explainable reports, and preserve audit history.
• GitHub delivery readiness — CI, repository structure, handoff documentation, release hygiene, and deterministic delivery checks.

My preferred delivery loop is: diagnose → implement → test → document → hand off.

My software work is informed by practical experience in:

• International trade
• Manufacturing operations
• Inventory management
• Purchasing and sales workflows
• ERP / MES / PLM-related systems
• Finance and accounting workflows
• Business process automation

I have independently developed and maintained ERP-related and internal business systems based on real operational needs.

I prefer software that is:

• Explicit about business rules and state transitions
• Covered by automated tests
• Verified through CI and browser-level validation where appropriate
• Auditable and explainable
• Designed with clear failure handling and operational boundaries
• Kept as simple as possible without sacrificing reliability
