Behind the scene, Beyond the screen

Service

I build secure, high-performance full-stack apps with smooth UX to drive growth not headaches.

Full-Stack Development

I design and ship end-to-end web products—aligning business requirements with clean architecture, precise UI/UX, efficient APIs, and production-grade quality.

01

Product Architecture

(Domain modeling, API contracts, modular boundaries, stack decisions driven by business needs)

02

Frontend Engineering

(React/Vue + TypeScript, predictable state, responsive layouts, smooth animations with GSAP/Framer Motion)

03

Backend & APIs

(Node.js/Express, Auth & RBAC, REST/GraphQL, payments/licensing integrations, file service & messaging)

DevOps & Cloud Solutions

Predictable, secure deployments. I set up CI/CD, automate infrastructure, and add observability so apps stay stable 24/7 on VPS or cloud—and scale without drama.

01

CI/CD Pipelines

(GitHub Actions, automated build & tests, versioning, zero-downtime deploys, fast rollbacks)

02

Infrastructure & Runtime

(Linux/Nginx, SSL, Docker/Compose, domains & subdomains, caching, SSR/Edge when it makes sense)

03

Observability

(Prometheus/Grafana, structured logging, alerting, basic tracing for rapid incident response)

Security & Performance

Security and speed together. I harden apps from code to server config while removing bottlenecks so the experience stays fast and safe as usage grows.

01

Application Hardening

(Input validation, rate limiting, XSS/SQLi protection, OAuth/JWT, secret management & dependency audits)

02

Performance Engineering

(Query/API profiling, indexing & caching, bundle optimization, realistic Lighthouse 90+ targets)

03

Quality Assurance

(Unit & integration tests, pragmatic e2e, architectural reviews & targeted refactors without blocking releases)

Web & Mobile Apps

Clear interfaces drive adoption. I build responsive, interactive web apps and mobile prototypes (React Native/Flutter) to validate ideas quickly and ship with confidence.

01

Rich Web Interfaces

(Precise UI/UX, accessibility, micro-interactions, intuitive navigation patterns)

02

Progressive Web Apps

(Offline mode, push notifications, smart caching strategies, installable experience)

03

Mobile Prototypes

(React Native/Flutter single codebase for fast validation, smooth handoff to production)

Cod with purpose, Built to scale

About

Clean architecture, premium UXI turn business needs into scalable systemsFrom first brief to production
man
Full-stack web developer who ships end-to-end. I translate requirements into clear domain models, pick the right stack, and deliver responsive, polished interfaces (React/Vue + TypeScript, GSAP/Framer Motion) backed by secure, efficient APIs (Node.js/Express, REST/GraphQL, Auth/RBAC) and optimized data layers (PostgreSQL/MySQL/Mongo via Prisma). I use Strapi for content workflows and n8n for automation/integration so teams move faster.On the ops side, I set up CI/CD (GitHub Actions), containerize with Docker, and run on VPS/cloud with Nginx, SSL, and caching. Observability with Prometheus/Grafana and structured logging keeps performance predictable and incidents short. The goal is simple: ship quickly, stay reliable, and leave a codebase the team enjoys maintaining.

Logic meets Aesthetics, Seamlessly

Works

Featured projects that have been meticulously crafted with passion to drive results and impact.
