View DetailsRestaurant Operations Platform
Production
A fully AI-backed server platform with desktop, web, and mobile surfaces for restaurant operations—ordering, inventory, reservations, and management—with intelligent import of whole restaurant datasets from mainstream platforms.
Problem
Multi-location restaurant teams need consistent operational tools, but moving from existing POS, ordering, or management systems often forces owners to re-enter menus, inventory, reservations, and reporting data from scratch.
Solution
Built an AI-backed server platform that imports restaurant data from mainstream platforms using server-side AI logic, then populates ordering, inventory, reservation, and management workflows across desktop and mobile without manual rebuild.
Cloud & Delivery
Fully implemented on AWS with AI-backed server logic for data import and daily operations, developed with AI coding-agent assistance under architecture, prompt, review, and acceptance-criteria control.

View DetailsLegacy Modernization & Data Migration Toolkit
Case Study
An anonymized modernization pattern for Delphi, WinForms, Access, SQL Server, and older database-driven systems.
Problem
Legacy systems often hold critical logic but lack documentation, test coverage, clean deployment paths, or reliable migration plans.
Solution
Analyze workflows, document domain logic, review data access, identify migration boundaries, and plan gradual replacement or refactoring with zero-downtime cutover planning where possible.
Cloud & Delivery
Uses phased migration planning, validation scripts, rollback thinking, and cutover design to protect data integrity and business continuity.

View DetailsAI Job Matching Platform
Production-ready Prototype
A production-ready Azure SaaS prototype for comparing resumes against job descriptions and supporting recruiter workflows.
Problem
Manual screening is slow, inconsistent, and hard to explain to candidates or hiring teams.
Solution
Designed component architecture, prompts, data flow, and acceptance criteria, then used agentic coding to implement the full product flow quickly with OpenAI API-backed job description analysis, resume analysis, matching logic, and explainable scoring.
Cloud & Delivery
Implemented on Azure and completed in one week through architecture-led AI agentic coding, with human planning, prompting, review, and product decisions guiding the build.

View DetailsAI Agent Coding Prompt System
Prototype
A structured prompt and workflow system for using AI coding agents in professional software development.
Problem
AI can create noise when tasks are underspecified, unreviewed, or disconnected from architecture decisions.
Solution
