Operational confidence · observability · control.
Core capabilities
Enterprise reliability, integration awareness, and a strong bias toward clean systems that are practical to operate.
Cybersecurity & Ethical Hacking
Web app testing, vulnerability assessment, API security testing, OWASP Top 10 awareness, reconnaissance, and responsible penetration testing workflows.
AI-Assisted Development
Using Claude, ChatGPT, and prompt engineering to plan features, generate code, debug, and ship practical products faster without losing product logic or testing discipline.
Android & Web App Building
Building Android apps, Next.js web platforms, admin panels, and dashboards using modern development workflows and AI-accelerated tooling.
Business Automation
ERP API integration, Excel and Google Sheets automation, WhatsApp marketing automation, document collection systems, and cost calculation tools for real business workflows.
API & Platform Integration
Meta WhatsApp Cloud API, ERP APIs, Supabase, Node.js backends, and custom integration layers connecting business platforms and data flows.
Desktop & Windows Tools
Building Windows utility apps, desktop productivity tools, and lightweight software with clean interfaces and practical use cases for daily work.
Featured projects
Each project is presented like a product story: what was broken, how the architecture moved, and what became more reliable after the work.
ColorVision — Automotive Color Formula Platform
Developed a professional automotive color mixing platform with 120,000 formulas, toner-based search, OEM brand references, and formula cost calculation.
WhatsApp Automation Platform
Created a WhatsApp marketing automation web app for bulk messaging, scheduled campaigns, customer list uploads, Meta API integration, and reply management.
Document Collection Automation System
Built an HR document collection automation system that generates unique upload links, organizes employee documents into structured folders, tracks submission status, and generates Excel reports.
ERP to Zoho ZATCA Compliance Integration
Designed and built an ERP-to-Zoho API integration for ZATCA e-invoicing compliance — any invoice created on the company ERP automatically passes through Zoho and submits to the ZATCA portal without manual steps.
Systems & integrations
The integration layer is presented as a clean enterprise pipeline. It shows how source systems, workflow logic, financial tools, storage, and reporting can move as one coordinated system.
End-to-end development process — six stages from idea to iteration
Identify the real-world problem, map the workflow, and define exactly what needs to be built.
Use Claude, ChatGPT, and prompt engineering to structure the workflow, plan features, and draft the first version.
Code with Next.js, Node.js, Android tools, or Excel/API automation depending on the project type.
Apply ethical hacking awareness — authentication, access control, input validation, and OWASP-aligned testing.
Docker VPS deployment, APK distribution, or client-ready Windows tool delivery with real-world testing.
Gather user feedback, identify friction points, and continuously improve the product based on real use.
- Normalized handoffs reduce brittle point-to-point logic.
- Workflow checkpoints create traceable operational state.
- Reporting persistence strengthens auditability and visibility.
This section proves systems thinking visually. It shows how operations, reporting, finance, and workflow logic can move through a deliberate architecture rather than a loose collection of tools.
Smaller product builds that still carry a premium systems voice.
Compact utilities and focused applications that show product thinking, interaction quality, and implementation discipline across different problem shapes.
