Project details
I focus on building custom platforms that turn complex data into actionable insights. For this project, I developed a Decision Intelligence solution tailored to HR teams, helping them forecast workforce needs, simulate scenarios, and align talent strategies with business goals.
The platform combines predictive analytics, interactive dashboards, and decision-support tools to simplify decision-making. With scalability, security, and usability at its core, it empowers HR leaders to move from reactive decisions to proactive, data-driven strategies.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
I work as a React developer / front end developer React, and also as a backend developer node.js (node) — often within MERN stack and full stack node.js environments.
On a daily basis, I build full stack node.js react products end-to-end.

I deliver end-to-end web applications as a full stack react developer, combining strong UI with reliable backend systems.
On the backend, I operate as a full stack developer node / full stack developer node js, building APIs, authentication flows, and integrations.
On the frontend, I create full stack react interfaces and components using javascript, react, and nextjs.
For unified systems, I connect frontend and backend using react node architecture, and I’m fully comfortable in full stack developer MERN projects.
This is real react full stack delivery — I take ownership as a react full stack developer, ensuring scalability, maintainability, and production readiness.
When needed, I step in as a CTO / software project manager, and even support as an ERP consultant for internal systems — covering architecture, roadmap, and execution with a strong focus on outcomes, timelines, and budgets.
I’m comfortable working in production environments:
- database design, migrations, performance optimization (DBA-level care)
- nginx basics
- payments (Stripe)
- integrations (Shopify)
- AI features (OpenAI)
I’ve built solutions across niche domains — med spa platforms, web3 apps, trading dashboards, and even perfume e-commerce websites. I’ve also implemented mechanics like coin flip systems, while respecting compliance and UX constraints (including gambling-related cases).
