Open to SDE-1 / new-grad roles · 2027
I build the backend of real-time products — sync servers, edit logs, rate limiters — and fix bugs in the open-source tools I use. Final-year Computer Science at BIT Mesra.
Featured project
A Google Docs–style editor with live cursors, offline editing, version history, full-text search and link sharing. I wrote the sync server, storage and auth myself on FastAPI, Yjs/pycrdt, PostgreSQL and Redis, and run it on free-tier hosting.
FastAPI WebSockets speak the Yjs sync and awareness protocols over pycrdt (Rust Yrs): one room per open document, per-connection send queues, and roles enforced on every update. Edits reach other users in about 110 ms in production.
Every edit lands in an append-only Postgres log, batched every 500 ms, then folds into snapshots under an advisory lock. Opening a 10,000-keystroke document went from 218 ms to 17 ms.
A token bucket in a single Redis Lua script: atomic across API instances, in one round trip, with fail-open or fail-closed per policy.
Argon2id passwords, 15-minute JWTs, rotating refresh tokens with reuse detection, and one-time 30-second WebSocket tickets.
The browser keeps an IndexedDB copy of each document; edits made offline merge automatically when the connection comes back.
173 API tests against real Postgres and Redis — including Hypothesis convergence properties — plus 79 web tests, and 10 architecture decision records.
Open source
I look for real bugs in tools I use, reduce them to a minimal reproduction, and fix them with regression tests. A few favourites:
microsoft/agent-framework #8660
is_type_compatible special-cased Any only as a target type, so workflow edge validation rejected executors declaring WorkflowContext[Any].
microsoft/agent-framework #8648
Middleware type detection failed under from __future__ import annotations; postponed (PEP 563) annotations are now resolved before dispatch.
One SELECT, AUTH or HELLO could silently move or re-authenticate the Redis connection shared by every later request; now refused at the provider boundary.
