About

Full-stack developer (TypeScript, Angular, NodeJS, PostgreSQL) who builds web app features end to end, from UI to database.

For the last two years I built a customer-facing insurance quote-to-policy web app for The Hartford (US insurer, through Cognizant): the Angular front end (landing page, application form, card-entry and policy issuance pages), the NodeJS REST backend those pages call, and the PostgreSQL schema behind it. On my own I’ve built Spring Boot services for JWT authentication, a Redis-cached product catalogue and Stripe payments with signed webhooks.

What you can hire me for: features or fixes in Angular or NodeJS codebases, REST APIs with PostgreSQL, a full-stack MVP flow from UI to database, and fast landing sites with a serverless contact form.

How I work: I confirm scope in writing, ship in small milestones and send a short written update after each working session. Available 4-6 hours a day with live overlap in the IST evening (EU afternoons, US East Coast mornings). AWS Certified Solutions Architect - Associate.

Three Java and Spring Boot services built as part of Scaler’s Full Stack Development program, covering the backend pieces most web apps need.

Authentication service ([code](https://www.twine.net/signin sign-up, login, logout and token validation, BCrypt password hashing, 24-hour JWTs backed by session records, Spring Authorization Server.

Product catalogue service ([code](https://www.twine.net/signin REST API on MySQL with Flyway schema migrations, Redis caching, and OAuth2 resource-server security that checks role claims.

Payment service ([code](https://www.twine.net/signin creates Stripe payment links behind a PaymentGateway interface (strategy pattern), so a second provider can be added without touching callers, and verifies signed Stripe webhooks.

Stack: Java, Spring Boot, Spring Security, Spring Data JPA, MySQL, Flyway, Redis, OAuth2/JWT, Stripe.
