EXPERIENCE
Full-Stack Developer (Internship) | Radency | April 2026 - May 2026
Project: ToolRent - B2C marketplace for renting tools and equipment
Back-End:
• Microservices architecture: developed services within a pnpm monorepo of 8 services communicating via RabbitMQ, applying
the CQRS pattern for separation of read and write operations.
• Real-time chat: implemented messaging between renters and companies on Socket.IO and RabbitMQ, with per-user soft
delete and file attachments.
• Files microservice: designed a storage abstraction over MinIO and AWS S3 with a presigned upload flow, which moved file
traffic off the application servers.
• Data layer: configured Prisma with a database-per-service PostgreSQL setup; developed migrations and deterministic seeders
keeping data consistent across services.
• Authentication and payments: integrated Auth0 with a Post Login Action exposing internal identifiers as custom JWT claims;
integrated Stripe Connect for marketplace payouts.
• AI service: built a conversational agent for tool search on Python, FastAPI and LangChain with OpenAI models, containerized
for local and cloud environments.
• Cloud infrastructure: described the environment as five CloudFormation stacks on AWS (ECS Fargate, RDS, S3, ALB, Secrets
Manager) and set up Docker Compose for the local environment.
Technologies: Nest.js, Node.js, TypeScript, Prisma, PostgreSQL, RabbitMQ, Socket.IO, Auth0, Stripe, Docker, AWS, Python, FastAPI,
LangChain
Front-End:
• Application architecture: developed the client application on React with TanStack Router and Query, Zustand for state and Zod
with React Hook Form for validation.
• Chat interface: built shared components reused by renter and company sides, with a socket hook invalidating the query cache
on incoming events.
• File uploads and UI: created reusable hooks for the presigned upload flow and implemented the interface with shadcn/ui and
Tailwind CSS.
Technologies: React, TypeScript, TanStack Router, TanStack Query, Zustand, Zod, React Hook Form, shadcn/ui, Tailwind CSS
