🚀 Open to senior backend roles (remote / hybrid)

Precision is freedom. Build systems that tell the truth.

• Senior Backend Engineer (6+ years) — production systems in Python and Go
• Focus: reliable microservices, async APIs, observability, and LLM-enabled backend features
• I maintain production SDKs, ship infra improvements, and enjoy turning vague reliability problems into measurable SLAs

• Core strengths: System design for scalability & reliability, asynchronous APIs, distributed task systems, cloud-native deployments
• Delivery: Led/maintained production SDKs (author/maintainer of imagekit-python), built observability pipelines and CI/CD workflows
• Special focus: Practical, engineering-first LLM/RAG integrations that are operationally safe and cost-aware

Languages & Frameworks

Databases & Caching

DevOps & Cloud

Monitoring & Observability

Tools: Celery, GitHub Actions, Prometheus, Grafana

• Production-ready SDK with tests and clear API surface
• Focus: reliability, backwards compatibility, and easy integration for client apps

• Small, focused repos that demonstrate safe prompting, cache strategies, and token-cost-aware batching
• Purpose: show pragmatic design for augmenting existing backends with LLM features without turning your infra into an invoicing disaster

• ✅ Open to senior backend roles where I can: own API surface, influence infra/observability, and ship LLM features responsibly
• 💰 Preferred compensation: market-competitive (USD / equity preferred), remote-first with occasional sync windows for IST overlap
• 🌍 Available: immediate — please DM on LinkedIn or connect below

1. Clear SLIs/SLAs and a roadmap to reach them
2. Observability-first designs that find problems before customers do
3. Incremental LLM integrations that respect latency, cost, and user intent

• 📍 Based in Kolkata, India. Calm about tradeoffs, allergic to vague roadmaps
• 🏋️ Outside work: disciplined fitness focus (currently working on sustainable fat loss and chest symmetry), learning French, and reading cognitive-science-adjacent books
