A collection of software projects, system designs, and anonymized project patterns focused on .NET enterprise systems, Azure/AWS cloud delivery, AI integration, agentic development, secure integrations, data workflows, and modernization.

Secure Online Payment Platform

Production

A production payment workflow with secure transaction processing, banking-style integration boundaries, auditability, and recurring compliance-focused upgrades.

Role

Backend engineer supporting secure integration design, implementation, regression planning, and production upgrade cycles.

Problem

Payment systems need reliability, traceability, controlled access, and low-risk upgrade paths without interrupting business operations.

Solution

Implemented backend payment workflows, integration contracts, validation, audit-oriented controls, regression planning, and annual upgrade support that passed stringent third-party security testing.

Architecture

API-first workflow with explicit request/response contracts, SQL Server-backed traceability, audit logging, access controls, and operational failure handling.

Cloud & Delivery

Fully implemented on AWS with production-oriented deployment, operational support, and compliance-focused upgrade planning.

Impact

Improved trust in recurring payment-platform upgrades by keeping security testing, release planning, and production continuity central to the work.

Restaurant 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.

Role

Architect/developer guiding server architecture, AI-backed import workflows, multi-surface product delivery, and acceptance criteria for agent-assisted implementation.

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.

Architecture

AWS-hosted server platform with AI-backed data normalization, operational modules, SQL Server/SQLite persistence, and desktop/web/mobile application surfaces.

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.

Impact

Reduced migration friction by allowing restaurants to transition existing operational data instead of rebuilding everything manually.
