01 — About

The Engineer Behind The Code

I am a Full-Stack Software Engineer based in Nigeria who builds pixel-perfect, high-performance interfaces backed by production-grade systems. I own features from Figma concept to deployed component — React 19 dashboards with TypeScript strict mode, Web Workers for main-thread isolation, and real-time data visualization. Then I wire them to Python/FastAPI backends with ACID-compliant PostgreSQL. Whether it is a banking ledger UI, a meteorological map with live API sync, or an async engineering control suite, I ship end-to-end.

03 — Career Path

Experience & Impact

Self-directed engineering with production systems handling real transactional data, encryption, and automated workflows.

2025 — Present

Full-Stack Software Engineer — Frontend-First

Independent / Self-Directed

Building and deploying production-grade interfaces and systems. Led frontend architecture for SyncOps (React 19/TypeScript dashboard with Web Workers), CENTURION (banking UI with real-time balance visualization), and Auto-Tm NG (interactive Leaflet mapping with live API sync). Backend systems include ACID-compliant PostgreSQL ledgers, client-side encryption modules, and Solana trading infrastructure. All deployed live with Docker on Render and GitHub Pages.

Foundations & Intensive Learning

Self-Directed Education

Intensive self-study in software engineering fundamentals. Mastered Python, JavaScript, and SQL through hands-on practice. Deep-dive into database internals (transaction isolation levels, WAL, ACID properties), cryptographic primitives (AES-256, ChaCha20, bcrypt), and Linux systems administration. Built foundational knowledge in REST API design, Git workflows, and containerization with Docker before transitioning to full project development in 2026.

Projects That Define Craft

Production-deployed interfaces and systems with live links, source code, and real user-facing experiences.

React 19 + TypeScript

01

SyncOps

Async Engineering Control Suite

A frontend architecture suite demonstrating async engineering patterns for distributed development teams. Features a Web Worker performance profiler benchmarking main-thread isolation under high-frequency data streams, a visual QA workbench with Figma overlay alignment for design drift detection, and a cross-border timezone orchestrator mapping global team availability windows. Built with React 19, TypeScript strict mode, and Vite.

Project CENTURION

Secure Banking & Scalable Ledger

A high-integrity banking core designed for transactional consistency. Built with ACID compliance using PostgreSQL row-level locking (with_for_update), Redis for high-speed session caching, and FastAPI for type-safe API endpoints. Protected against double-spend via idempotency keys.

Live API Sync

03

Auto-Tm NG

Next-Gen Workflow Automation

An automation engine streamlining repetitive tasks and optimizing system workflows. Features a real-time map interface synced with live meteorological APIs, ZTD (Zenith Total Delay) calculations, and convective moisture monitoring for GNSS-station reference data across Nigeria.

Client-Side Crypto

04

VAULT X2

Advanced Data Encryption

A dedicated security module handling sensitive data storage with modern cryptographic standards. Implements AES-256 and ChaCha20 encryption ensuring data remains protected both at rest and in transit. Features a clean drag-and-drop interface for file encryption/decryption with password-derived keys.

Sol-Tee Bot

Pump.fun Migration Alert System

A real-time Solana token scanner that monitors Pump.fun bonding curves via WebSocket and sends Telegram alerts when tokens approach Raydium migration. Features on-chain safety filters (whale concentration, dev wallet history, honeypot detection), narrative scoring against trending keywords, and milestone tracking (2x–100x) with live performance stats. Built with async Python, Helius RPC, and SQLite persistence.

Blitz Compress

High-Performance Lossless Compression Engine

A from-scratch lossless compression engine in Rust, built to demonstrate deep systems-level thinking and hardware-conscious algorithm design. Features L1-cache-sized hash tables (32KB), single-pointer collision resolution for branch prediction, greedy parsing for ILP, SIMD-accelerated memory copies (AVX2/NEON), and FSE entropy coding. Achieves 250x compression on repetitive data at 1.36 GiB/s throughput — competitive with LZ4 and Zstd on small data due to minimal overhead. 45+ tests, full benchmark suite included.
