OakFrog Labs
A standalone tools website with browser utilities, calculators, typing practice, and interactive features.
Problem
Useful tools need to be fast, focused, and easy to revisit without competing with the personal portfolio narrative.
Solution
Built a separate tools product with a clear homepage, persistent local history, serverless endpoints, wishlist submissions, admin moderation, calculators, text/code utilities, and Color Clash as an interactive feature.

Problem
Useful tools need to be fast, focused, and easy to revisit without competing with the personal portfolio narrative.
Solution
Built a separate tools product with a clear homepage, persistent local history, serverless endpoints, wishlist submissions, admin moderation, calculators, text/code utilities, and Color Clash as an interactive feature.
Architecture
Built as a separate Next.js application deployed independently on Vercel, using client-side tools for instant transformations, serverless APIs for shared public features, localStorage for per-device history, and a hidden admin route protected by environment secrets.
Impact
- Separates personal branding from repeat-use product functionality.
- Demonstrates product scope, public submissions, admin control, SEO, responsive UI, and deployment ownership.
- Shows experience building software that is useful beyond a static portfolio page.

Solution
Built a fast, SEO-optimized frontend with custom components and a cleaner information hierarchy, balancing business goals with maintainable implementation patterns.
Architecture
Structured the frontend around reusable UI sections and performance-conscious rendering, keeping the codebase flexible for future iteration while supporting production reliability.
Impact
- Delivered a production experience for a US-facing business.
- Improved search visibility and perceived product quality through tailored frontend implementation.
- Used custom components instead of template-driven design, reinforcing a stronger brand presence.

Problem
Workflow-heavy business software requires careful handling of state, permissions, auditability, and high-density data.
Solution
Designed a public, anonymized workflow system blueprint with queues, approval phases, escalation states, status-safe actions, and reusable data table patterns.
Architecture
Modeled as a Next.js product surface backed by API-ready domain objects: workflow definitions, phase transitions, activity logs, reviewers, and filtered work queues.
Impact
- Turns enterprise workflow experience into a public technical case study.
- Demonstrates strengths in workflow logic, status pipelines, operational UX, and scalable frontend structure.
- Shows the ability to translate complex business processes into understandable product interfaces.

Problem
Backend reliability work becomes easier to understand when service health, response time, and incidents are visible in one operational surface.
Solution
Designed a dashboard surface that visualizes service uptime, endpoint checks, response trends, incident notes, and deployment readiness.
Architecture
Designed around API health routes, scheduled checks, normalized service metrics, and status summaries that could later connect to .NET services, queues, and cloud logs.
Impact
- Highlights backend and system reliability thinking without exposing company infrastructure.
- Shows comfort with production operations, not only feature delivery.
- Creates a clear foundation for cron checks, persistence, and service-level history.
