Building reliable systems & data at scale

I'm Om, an engineer who turns messy, heterogeneous data into fast, resilient, production-grade workflows. I work across backend, distributed systems, and LLM-powered products.

01 About
Portrait of Om Dubey
Om Dubey, SWE

I build things end to end, from data-ingestion pipelines and event-driven services to hardening auth and squeezing out performance.

I care about reliable, idempotent code that survives the real world: retries, rate limits, checkpoints, and circuit breakers. Lately I've gone deep on LLM-assisted data workflows like structured extraction, embeddings, and hybrid retrieval, while shipping open-source developer tools on the side.

Free Bulk Delete for Slack

2026 · 5.0★ TypeScript · Preact · Manifest V3 · Slack API · Vitest

Open-source Chrome extension for bulk-deleting Slack messages across channels, DMs, and group chats. It's backend-free and local-only, so it reuses your authenticated session with zero accounts, analytics, or external data transfer. It reached 30+ users with a perfect 5.0/5 rating, backed by 52 Vitest cases covering pagination, retries, filters, and cancellation.

Zeer AI

Software Engineer
  • Built data-ingestion pipelines for B2B intent signals from websites, Excel/CSV, private Slack communities, and social-data sources, normalizing heterogeneous records into PostgreSQL for enrichment and search.
  • Developed a Python Slack ingestion service (Playwright, httpx, SQLAlchemy/Alembic, DBOS) with per-channel checkpoints, lease-based single-runner control, 1,000-row buffered upserts, and retry/backoff for resumable scrapes.
  • Implemented LLM-assisted extraction and classification with OpenAI structured outputs, embeddings, and hybrid retrieval (Qdrant + pgvector), plus evaluation and usage tracking.
  • Engineered resumable, event-driven processing across TypeScript and Python services (BullMQ, Redis, DBOS, PostgreSQL) with idempotent writes, rate-limit handling, retries, and circuit breakers.

Software Development Engineer I
  • Improved a search API's performance by 60% through pagination and wrote 15+ edge-case tests, raising coverage to 95%.
  • Migrated email notifications from synchronous HTTP to Kafka-based processing, which cut service-call latency from 200ms to 50ms and inter-service latency by 40%.
  • Hardened OAuth 2.0 auth by caching access tokens in Redis, invalidating rotated refresh tokens, and publishing login/logout audit events to a Kafka-backed audit service.
