about me

hey, i'm subhraneel. final year cs student from kolkata, india. i build production ready fullstack applications and real time backend infra. (i like backend more haha)

who i am

i'm someone who actually ships things. not just demos or side projects that sit on github. i like to write production ready code that people can use. i care about clean code, good architecture, and building things the right way.

currently in my final year at IEM, kolkata (graduating may 2026). but honestly, i've been learning more from building real products and working on my sideprojects than from classes, haha.

i've also been a founding engineer at kasukabe labs (an agency that me and my homies have built) where we shipped freelance client projects, apps, and chrome extensions.

what i do

here's what i'm good at:

• building real time systems (websockets, trpc, low latency stuff)
• fullstack development (comfortable with both frontend and backend)
• ai integrations
• clean architecture and code practices
• authentication and authorization flows
• proper error handling
• scalable apis and data handling
• open source development

my stack

languages: typescript (main), javascript, java, sql

frontend: react, next.js (app router, rsc), html5, css3, tailwind css, shadcn/ui

backend: node.js, rest apis, trpc, websockets, server actions, authentication, authorization, jwt

databases: postgresql, mongodb, prisma orm

ai stuff: gemini api, openai api, vercel ai sdk, eleven labs

infrastructure: vercel, neondb, aws, docker, gcp

tools: git, github, cursor

what i've built

study toolkit (open sourced)

what's in it:

• credit based ai usage (300 free credits)
• smart token costing based on what tool you're using
• fallback system so you can plug in your own gemini api key when credits run out
• react server components and server actions for secure, optimized data handling
• clean ui that doesn't distract you with unnecessary features
• fully open sourced and well documented

learned a ton building this:

• server actions in next.js
• using vercel ai sdk properly
• ai elements from vercel
• rsc (react server components)
• writing good github commits
• bunch of useful git commands like git rebase
• shared everything on twitter/x, got feedback and iterated on it

realtime notification service

technical stuff:

• authenticated websocket connections that trigger on user login
• end to end jwt authentication flow
• full e2e post like flow where events update the db and async trigger notifications
• websocket server emits multiple events (like_ack to the person who liked, notification to the post author)
• prisma with postgresql (neondb) for storage
• fully documented everything architecture, event flows, payloads, diagrams

ai chrome extension and jobs portal (at jobsforce llc)

worked as a fullstack developer intern at jobsforce llc (san francisco, remote) from march to september 2025.

built an ai powered chrome extension using plasmo. implemented real time communication between llms and users with websockets and node.js in their jobs portal for realtime ai mock interview feature. handled scalable frontend data for 5000+ job listings using pagination and infinite scroll. designed secure authentication apis with role based access control.

worked across the entire stack to ship production ready features.

what i'm building now

currently working on a one shot ai video generator platform using latest tech and local models. exploring cutting edge stuff in ai video generation.

how i work

i also like building in public and sharing what i'm learning, getting feedback, iterating. twitter/x has been great for this.

i'm comfortable working end to end, from database design to production deployment. i handle both the frontend polish and the backend complexity. i ship complete features, not half finished implementations.

work style

• i prefer direct, clear communication
• happy to hop on quick chats or calls
• open to take home assessments
• comfortable working remotely
• active on twitter/x and github
• strong git workflow (good commits, rebasing, proper branching)
• i document things well so others can understand the codebase

what i care about

clean architecture: i care about writing maintainable code that makes sense. its simple, readable and makes sense with proper documentation.

production reliability: everything i build is meant to actually work in production, not just look good in a demo.

security: proper auth flows, jwt handling, role based access control, middlewares and proper error messages things matter.

user focused design: i build practical solutions. distraction free ui that solve real problems.

open source: i believe in transparent, extensible code that others can learn from and build on, so i document them properly in easy to understand lang.

currently

• actively looking for swe roles
• interested in companies building real time systems, ai products, or developer tools
• open to remote opportunities
• can start immediately
• located in kolkata, west bengal, india (ist timezone)

quick summary for context

i build and ship fullstack systems. recently built an open source ai study platform with credit based usage and server components. designed a realtime notification service with websockets and trpc. worked as a fullstack intern building ai chrome extensions and realtime llm integrations. consistently focused on clean architecture, secure flows, and production reliability. founding engineer at kasukabe labs shipping client projects.
