Planning and Building a Specialized Multi-Tenant SaaS CMS

Planning and developing a multi-tenant SaaS content platform that will give small and medium-sized businesses in a specialized market a responsive, customizable web application without exposing the product's protected vertical concept.

TL;DR

Problem: A specialized SMB market needs responsive, configurable web applications without the cost and fragmentation of one-off development
Solution: Design a multi-tenant SaaS CMS with tenant isolation, role-based administration, reusable components, and configuration-driven presentation
Impact: Creates a scalable path from one focused implementation to a repeatable product while protecting the underlying market concept

Multi-Tenant SaaSDelivery Model

Role BasedAccess Model

CRUD + Soft DeleteContent Lifecycle

In DevelopmentCurrent Stage

Technical Leadership

Defined the product boundary between reusable platform capabilities and tenant-owned content and appearance configuration.
Planned a role model covering platform administration, tenant ownership, delegated content management, and public users.
Designed customization as structured configuration rather than customer-specific source-code branches.

Outcome:Established the product architecture, configurable presentation system, administrative boundaries, and phased delivery plan needed to evolve a focused prototype into a secure SaaS platform.

Strengthening a C# Chess Game Rules Engine

Extended a tutorial-based C# and WPF chess application with independently developed king-safety validation, castling rules, captured-piece tracking, and a computer-controlled opponent.

TL;DR

Problem: The guided implementation needed stronger rule enforcement and a playable single-player experience
Solution: Added board-copy simulation, king-safety filtering, castling validation, captured-piece tracking, and a material-scoring Black AI
Impact: Produced a clearer demonstration of C# architecture, game-state reasoning, and desktop UI integration

2Solution Projects

Technical Leadership

Kept chess rules in the ChessLogic project and presentation concerns in ChessUI rather than embedding engine behavior in event handlers.
Used copied board states to validate candidate moves without mutating the active game.
Designed the computer opponent to consume the same legal-move pipeline used by the human-facing game flow.

Outcome:Turned a guided implementation into a stronger portfolio project that demonstrates object-oriented game architecture, rule validation, board-state simulation, and asynchronous UI coordination.

Connecting a Frontend Prototype to a Production Multiplayer Platform

Connected an Angular multiplayer game platform to a newly developed Fastify backend by incrementally replacing client-side functionality with authenticated API-driven workflows while preserving gameplay continuity and maintaining production stability.

TL;DR

Problem: A frontend-only game engine needed to evolve into a production multiplayer platform without disrupting existing gameplay.
Solution: Incrementally replaced local functionality with authenticated API integrations while expanding backend capabilities.
Impact: Delivered a fully connected production platform with persistent state, administration tooling, and scalable architecture.

Frontend + APIDeployment Targets

Technical Leadership

Defined an incremental integration strategy that minimized risk while connecting frontend and backend systems.
Identified opportunities to replace local functionality one API at a time rather than attempting a large-scale rewrite.
Designed API contracts that mirrored existing frontend game actions to simplify migration.

Outcome:Successfully transformed a frontend-first prototype into a full-stack production platform supporting authenticated users, persistent game state, multiplayer gameplay, administration features, and scalable backend services.

Building a Rules-Rich Chess Game with Python and Pygame

Expanded a Pygame chess project into a two-player desktop game with complete piece movement, castling, en passant, promotion, move history, captures, check feedback, and experimental MySQL persistence.

TL;DR

Problem: Chess rules and UI feedback depended on shared mutable state that became more complex with every added feature
Solution: Implement movement generation, special rules, captures, move history, check feedback, and persistence experiments around a common board representation
Impact: Produced a playable Pygame project and a concrete roadmap toward cleaner domain modeling and testable rule boundaries

PythonPrimary Language

PygameUI Framework

3 ImplementedSpecial Rules

Technical Leadership

Extended the learning project with state-dependent rules including both castling directions, en passant, and selectable pawn promotion.
Connected move generation to visual previews so players can inspect candidate destinations before committing a move.
Tracked captures, turn progression, check state, move history, forfeits, game-over state, and restart behavior in one playable workflow.

Outcome:Created a substantial Python learning project that demonstrates rules-heavy state management while also revealing clear opportunities for domain modeling, automated testing, and persistence boundaries.

Modeling a React Chess Rules Engine with TypeScript

Built a React and TypeScript chess application that combines drag-and-drop interaction with object-oriented board models, legal-move previews, king-safety rules, castling, en passant, promotion, and checkmate handling.

TL;DR

Problem: Direct board interaction had to remain subordinate to legal chess state and React update rules
Solution: Combine focused UI components with cloneable Board, Piece, Pawn, and Position models that recalculate legal moves after state transitions
Impact: Produced a typed React chess experience with move previews, special rules, promotion, and checkmate feedback

Clone + RecalculateState Model

Drag and DropInteraction

Technical Leadership

Separated tile rendering and drag behavior from the Referee component that coordinates accepted moves and game-level UI state.
Modeled board positions and chess pieces with TypeScript classes, cloning behavior, and piece-specific possible-move calculation.
Used functional React state updates to clone the prior board, apply an accepted move, increment turns, and expose the next state.

Outcome:Demonstrated how component state and typed domain objects can cooperate in a rules-heavy interface while keeping board recalculation separate from visual tile rendering.
