Senior Software Engineer

Shaban Khawar

Claude Specialist. I build AI-native systems — and the engineering that keeps them standing.

Agents, LLM pipelines, and the full stack underneath: Next.js, NestJS, Django, Postgres, AWS.

An illustration of a production voice-to-notes pipeline: audio upload, FFmpeg normalisation on Lambda, Whisper transcription with retries, summarisation under a token budget, schema validation, idempotent persistence to Postgres, and a Notion sync.

01

Idempotent by default

Retries, replays, and duplicate deliveries are table stakes, not edge cases.

02

Evals before vibes

If a model's output can't be measured, it isn't ready to ship.

03

Token budgets are budgets

Cost and latency per request are design constraints, decided up front.

04

Boring infrastructure

Postgres, queues, cron. Novelty where it earns its keep, nowhere else.

About

Most AI features die in the gap between demo and Tuesday. That gap is where I work: retries, idempotency, token budgets, evals — the boring parts nobody screenshots.

Five years shipping production systems — transcription pipelines, voice-generation platforms, subscription billing, async collaboration tools. Backend, frontend, and the DevOps underneath, chosen per problem rather than per résumé.

Core is what I reach for by default. The rest I'm productive in when the problem calls for it.
