About
Building systems that scale
From architecture to deployment — I enjoy crafting complete solutions.
I'm a software engineer passionate about building robust, scalable systems that solve real-world problems. My journey spans the full stack — from crafting intuitive frontend experiences to designing resilient backend architectures and deploying them on cloud infrastructure.
I thrive at the intersection of engineering disciplines: building REST APIs with proper authentication and authorization, containerizing applications with Docker, automating deployments through CI/CD pipelines, and integrating AI capabilities into modern web applications.
What drives me is the complete picture — taking a system from initial architecture decisions through development, security hardening, cloud deployment, and production monitoring. I believe great software is built by engineers who understand every layer of the stack.

Building Blocks
Core architectural patterns
01
Monolith
Unified application architecture with shared codebase, ideal for rapid development and simpler deployment pipelines.
02
REST APIs
Stateless HTTP APIs with resource-oriented endpoints, versioning, and standardized request/response contracts.
03
Authentication Flow
JWT/OAuth-based auth with secure token management, refresh flows, and role-based access control middleware.
04
Frontend
React/Next.js SPAs with component-driven architecture, state management, and optimized rendering strategies.
05
Backend
Node.js services with layered architecture — routes, controllers, services, and data access layers.
06
Database
MongoDB/PostgreSQL with schema design, indexing, connection pooling, and migration strategies.
07
Cloud
AWS infrastructure with EC2 compute, S3 storage, IAM policies, and CloudWatch monitoring.
08
Deployment
Docker containerization, CI/CD pipelines, reverse proxy configuration, and zero-downtime deployments.
Security
Security-first engineering
Building applications with defense-in-depth from day one.
JWT
Stateless token-based authentication with secure signing and expiration policies.
RBAC
Role-based access control enforcing permissions at API and resource levels.
Authentication
Multi-factor ready login flows with secure session and token management.
Authorization
Granular permission checks ensuring users access only authorized resources.
HTTPS
