Freelance Marketplace Platform

  • Marketplace-oriented microservices architecture: Independent services in Node.js, Express and TypeScript for authentication, users, gigs, chat, orders, reviews and notifications, following the database-per-service pattern and event-driven communication.
  • Automation and cloud deployment: Containerized workloads with Docker and orchestrated with Kubernetes (Minikube and AWS EKS), promoted between environments through CI/CD pipelines in Jenkins.
  • Data, messaging and observability: Integration of RabbitMQ, Redis, PostgreSQL, MySQL and MongoDB, with centralized observability using Elasticsearch/Kibana, Prometheus and Grafana for logging, metrics and traceability.
  • Frontend delivery: Web client developed in React, Tailwind CSS and TypeScript, consuming microservices APIs for a responsive and real-time user experience.

Ritual Roast · Architecture evolution on AWS

Application with a Next.js frontend and a Flask backend. All AWS infrastructure is provisioned and automated with Terraform, so each version can be deployed, evolved and reproduced in a controlled way.

  • v1 · Three-tier architecture on EC2: Baseline with a multi-AZ VPC, ALB, ASG, EC2, RDS MySQL Multi-AZ, NAT Gateway, Secrets Manager and IAM — separating DMZ, application and data tiers with dedicated security groups.
  • v2 · Containers on ECS Fargate: Workloads containerized on ECS Fargate with images in ECR, ALB target groups and RDS Multi-AZ — removing direct server management and packaging Next.js and Flask as independent services with consistent deployments.
  • v3 · Serverless architecture: CloudFront and S3 for the static frontend, API Gateway as the entry point, Lambda functions for business logic and DynamoDB as the data store — minimizing infrastructure operations and scaling purely on demand.
  • Governance · Multi-account governance: AWS Organizations with management, development and production accounts, SCPs and cross-account IAM roles — enforcing centralized controls, security and compliance as the architecture grows.

TechShot Online Store

  • Professional MERN stack: Frontend in React with hooks, React Router, Redux Toolkit and React-Bootstrap; backend in Node.js/Express with Mongoose, seeders and CLI scripts to model the domain.
  • Catalog and shopping UX: Pagination, search, featured carousel, authenticated reviews and ratings, cart with dynamic quantities and multi-stage checkout.
  • Security and payments: JWT authentication with HTTP-only cookies, bcrypt, custom middlewares, structured error handling and PayPal REST SDK integration.
  • Operational management: Admin console for product CRUD, user management, order details with delivery marking, environment variable configuration and production deployment.
Social media app cover

Social Network

  • Realtime MERN: React with hooks and Context API, Express/Node and MongoDB orchestrated with JWT for login/registration, invitations and presence.
  • Chat and signaling: Socket.IO as event bus for instant messaging, friend management and video call room coordination.
  • Simplified WebRTC: Integration with simple-peer to create group call rooms with automated peer-to-peer negotiation.
  • Collaborative experience: Responsive UI with Material UI, real-time synchronized states and production-ready deployment to showcase.
