01 / Overview
A full-stack cryptocurrency trading, educational, and utility settlement platform bridging live professional signals, structured academy courses, and multi-category bill payments with internal digital wallet management.
The Core Purpose
A Unified FinTech & EdTech Ecosystem for Crypto Traders
02 / The Problem
The client ran a growing crypto community across fragmented channels: VIP signals were shared on Telegram, courses lived on external video tools, and payments were tracked manually across bank transfers and crypto wallets with high error rates.
03 / What I Did
Commissioned via CodeRigi as Lead Full-Stack Architect. I unified the client's fragmented business into a single cohesive platform — architecting the database schema, building payment gateways, creating the academy LMS, and developing the mobile and web interfaces.
04 / How I Thought About It
Traders need continuous momentum: they learn market strategies, receive live trade signals, and want to settle everyday utility expenses directly from their trading profits. By designing a centralized multi-gateway wallet, the platform keeps users inside one trusted financial loop.
05 / What I Built
A multi-currency digital wallet (Paystack, Chipper Cash, crypto verification), automated subscription gating for VIP signals, a nested course LMS (Course -> Plan -> Topic), an automated utility bill settlement engine across 15 categories, and responsive dashboards.
06 / The Architecture & System
Developed using Laravel with Eloquent ORM, multi-guard authentication with OTP verification, Paystack and utility billing APIs, double-entry ledgers, and responsive Bootstrap 5 interface.
Technical Stack & Infrastructure
PHP / Laravel · MySQL · FinTech Wallets · Paystack API · Crypto Ledgers · Utility Billing APIs · EdTech LMS
07 / The Result
Delivered a unified platform that automated course enrollments across 20+ database models, handled fiat and crypto deposit workflows, and processed utility settlements without manual intervention.

Lead Full-Stack Architect
The Lesson
Financial applications require rigorous attention to referential integrity and idempotent processing. Implementing null-safe fallbacks for orphaned records is the difference between smooth operations and costly downtime.
