I work on security data platforms at MiniOrange: DLP detection, SIEM log forwarding, and multi-tenant export pipelines. Outside work I build the same kind of systems from scratch in Go and Python, with a competitive programming background behind the algorithms.
DEMOA multi-tenant data loss prevention platform: an outbound email gateway that inspects every message before it leaves, plus a scanner that finds sensitive data in cloud storage.
OUTBOX: SKIP LOCKED RELAY · DLQ REPLAYABLE
A platform for running an online tutoring business: each organisation gets its own isolated space for staff, courses, batches, live classes, and files.
DEMOAn AI career assistant that scores and rewrites resumes with retrieval-augmented generation and generates full learning courses in the background.
01 // CORE
APIs, queue consumers, and batch pipelines designed for the case where a worker dies mid-job, with retries, recovery, and dead-letter handling built in.
02 // DELIVERY
Taking a feature from the database schema to a working dashboard, including auth flows, admin consoles, and localisation.
03 // DEFENCE
Data loss prevention, SIEM log forwarding, token rotation, tenant isolation, and encryption of stored credentials.
04 // FOUNDATIONS
Competitive programming applied to production problems: similarity search, multi-pattern matching, rate limiting, and fair scheduling.
The interesting part of a system is usually the part nobody sees until it fails: the queue that has to survive a crash, or the check that has to be right every time.
I'm a backend engineer at MiniOrange in Pune, where I work on security data platforms: a fingerprint-based DLP engine for endpoints, a SIEM log-forwarding service, cloud data discovery connectors, and a bulk-export pipeline that processes over ten million events per run.
I came to backend work through competitive programming at M.B.M University, Jodhpur. I qualified for the ICPC Asia Regional in 2023, reached Specialist on Codeforces across 37 rated contests, and have solved more than 1,200 problems across Codeforces, LeetCode, and CodeChef.

01
SecurePlus returns an SMTP 250 only after the message is in the stream, and TutorPilot writes its events in the same transaction as the data. A success response should mean the work cannot be lost.
02
Every queue consumer I build can reclaim stalled messages, resume half-finished jobs on restart, and park poison messages somewhere they can be replayed.
03
Tenant boundaries belong in keys and schemas, like a JWT secret per organisation, rather than in a filter someone might forget to add to a query.
04
The happy path is the easy part. My tests also cover rollbacks, reused tokens, oversized files, and hostile regex patterns.
I'm looking for backend engineering roles in distributed systems, high-throughput pipelines, or security infrastructure, remote or with relocation. I'm also happy to talk about any of the projects here.
