I don't just write code; I build practical digital solutions that solve real-world problems.
As a Computer Engineering Specialist and the founder of Yhiskotech
Digital Solution Hubs, I focus on engineering full-stack web systems that are fast,
efficient, and built to scale.
My approach to development is rooted in understanding the core architecture behind the UI.
I specialize in engineering robust client-side applications, scalable APIs,
and efficient backends using pure Vanilla JavaScript, Node.js, and MongoDB
to ensure maximum performance and clean logic. A prime example of this is
Yhisko Records — a system built from the ground up for speed and
architectural clarity, a WhatsApp-integrated business management system I engineered to help
small business owners seamlessly track sales, handle profit/loss analytics, and manage
customer debts in real time.
Beyond software development, my engineering background spans IT network defense,
hardware diagnostics, phone technician work, and digital branding. Whether I'm
optimizing web performance for high-converting platforms or securing network infrastructure,
I approach every project with strict technical precision.
I build in public, continuously refine my craft, and always design with the end-user's growth
in mind. Let's connect and build something impactful.
End-to-end web and backend systems — frontend, APIs, databases, deployment.
Content edits for YouTube, ads and social media built to hold attention.
Diagnostics and repair — screens, charging ports, batteries, boards.
Network setup, system hardening and practical security guidance.
Teaching programming and web development to beginners and students.
Logos, social media graphics and brand visuals for businesses.
WhatsApp-based business management system for Nigerian SMBs — receipts, reports, expenses, debt tracking, staff management and AI-powered insights.
A real-world business website bringing a pastries and events business online — customers can explore services, view offerings, and reach out directly.
A Facebook-inspired social media UI built entirely from scratch — responsive, interactive, with full light and dark mode support.
A post editor with live preview, drag-and-drop media uploads, post editing after publish, undo/redo, and LinkedIn-style comments and reactions.
Available for freelance work, full-time roles, or collaborations. I reply fast.
