Beauty and booking

1. Tife Beauty Lounge

A booking platform with live chat, payment integration, and a promotions engine, backed by a secure database and an admin dashboard so the business can manage pricing, promotions, and client conversations.

Case Study

The CEO of Tife Beauty Lounge ran her entire client pipeline through Instagram and WhatsApp DMs until an account suspension cut her off from every lead and conversation overnight. She needed a replacement: a booking platform with live chat, payment integration, and a promotions engine, and an admin dashboard so she can manage clients herself.

Contribution

I designed the data model with RLS policies so guest bookings and chat never touch privileged data directly. I built a single pricing engine shared across the booking flow and chat, combining service-level promo pricing, scheduled sitewide/category sales, and promo codes, so a discount never means charging the wrong amount. I also extended live chat beyond plain text to structured message types i.e. booking confirmation cards, images, video, and links, backed by a Gemini-powered assistant that answers from the studio's real pricing and FAQ data instead of a scripted flow, with a fast keyword-matched path handling common questions before ever calling the LLM, and an activity-aware handoff so the bot goes quiet the moment the owner is actively replying.

Outcome

A booking and support channel that isn't at the mercy of a platform suspension, with every conversation and client record owned in her own database. An admin dashboard lets her update pricing, run promotions, and manage bookings without waiting on a developer. The pricing and promo-code logic is validated server-side end to end — usage limits, date windows, and service restrictions are enforced atomically, closing gaps that are easy to miss in a first pass at e-commerce discounting.

3. Wallet Expense - Your Personal Financial Companion

A personal finance platform that brings expenses, budgets, planned payments, shared finances, and financial insights into one place, with an architecture designed to support intelligent transaction categorization, automated savings, and bank integrations.

Case Study

Managing personal finances often means piecing together information from bank statements, spreadsheets, payment notifications, and memory. I wanted to build a system that could turn that fragmented data into a single financial picture: what came in, where it went, what had already been committed, and whether spending was actually aligned with the user's plans. It needed to be designed as a personal financial companion rather than another expense tracker, combining transaction management, budgeting, shared finances, planned payments, reminders, and financial projections into one product.

Contribution

I designed and engineered the core product architecture, from the data model and backend workflows to the frontend experience and state-management layer. I built the transaction and budgeting systems around structured financial records, implemented reusable React interfaces with Redux Toolkit and RTK Query, and used Supabase/PostgreSQL for authentication, persistence, and backend functionality. Beyond the core tracking experience, I designed the architecture for automated expense categorization, round-up savings, wealth-growth projections, missing-transaction detection, shared budgets, planned payments, and reminder workflows. I also structured the product so capabilities such as direct bank synchronization and SMS-based transaction parsing could be added without having to redesign the underlying financial model.

Outcome

A functional fintech product that moves beyond recording transactions to helping users understand and act on their financial position. The architecture supports multiple financial workflows without treating each feature as an isolated system, giving transactions, budgets, planned payments, and financial insights a shared foundation. The project demonstrates my ability to take a product from concept through system architecture, database design, frontend engineering, state management, and implementation, while designing for capabilities that extend beyond the initial MVP.

Church operations and management

4. HovaSee - Church Management and Operations

A role-aware church operations platform that replaces fragmented WhatsApp updates, spreadsheets, and manual reporting with structured workflows for attendance, small groups, workforce management, visitor follow-up, and leadership reporting.

Case Study

Church operations were being coordinated across WhatsApp messages, spreadsheets, forms, and manual follow-ups, making it difficult for leadership to know what was happening across campuses and small groups without chasing people for updates. HovaSee was designed to replace that fragmented process with a single operational system where responsibilities, reports, attendance, people, and follow-up activities are connected. The goal was to turn recurring administrative processes into structured workflows that could be tracked from assignment through completion.

Contribution

I designed and engineered the platform architecture around a multi-campus, role-aware model, covering authentication, onboarding, organizational structure, reporting, small groups, workforce management, and visitor follow-up. I built workflows for Sunday attendance, first-timers, new converts, small-group attendance, outreach, and financial reporting, while designing the underlying infrastructure to support additional reporting domains without exposing unnecessary complexity in the MVP. I also built the visitor assimilation workflow from first-time registration through assignment, contact attempts, small-group invitation, integration, escalation, and loss, with automated assignment and rotation workflows for operational teams. Supabase/PostgreSQL provided the data layer, authentication, and security model, with Row-Level Security used to control access to church and operational data.

Outcome

A centralized operations platform that gives church leadership structured visibility into what is happening across people, campuses, small groups, reports, and follow-up activities. Instead of relying on disconnected messages and spreadsheets, leaders can work from defined responsibilities and measurable workflow states, while operational teams have a clear path from assignment to completion. The architecture also provides a foundation for automation and analytics, making it possible to measure follow-up effectiveness, completion rates, response times, escalations, and integration outcomes as the platform grows.
