I take products from zero to one — then scale them to 100× the load. Data pipelines, distributed backends and AI agents that hold up in production.

01 About

About Manas Mishra, backend and AI engineer in Bangalore

I'm happiest in the parts of a product nobody sees — the queues, migrations, pipelines and agents — making them fast, reliable and worth what they cost.

I'm a backend and AI engineer (SDE-2) with 5 years of experience — 4.5 years full-time plus a 6-month internship — building scalable, cloud-native systems in Python — Django, FastAPI and microservices on AWS, Azure and GCP. As a founding engineer at Datavio in Bangalore, I work closely with the CTO on a 0→1 data-analytics platform for brands selling on e-commerce and quick-commerce — owning architecture, deployment and post-launch optimization.

Before that, I was the technical co-founder of Bentofi, where I built an MVP that automated the manual workflows of CA firms — GST returns and reconciliation, bookkeeping and client documents — and worked with our first two clients.

Lately I've been building AI that earns its keep in production: an autonomous data-analysis agent on the OpenAI Agents SDK, agentic workflows that automate supply-chain operations, and llm-graph-optimizer, which finds the LangGraph nodes that don't need an expensive model.

Find the LangGraph nodes that don't need an expensive model.

One line instruments a compiled graph. lgo shadow replays real traffic through a lighter model, and lgo report shows per-node cost, latency and agreement — with no changes to the agent.

DatavioData engineering

Vendor-portal integrations

Reliable data from platforms that never shipped an API.

Playwright connectors log in like a person — CAPTCHA and sessions handled — then pull reports from inside the authenticated page and land clean rows in Postgres.

DatavioAI agents

AI data-analysis agent

Ask a question; the agent plans the analysis.

Built from scratch on the OpenAI Agents SDK: it breaks a question into steps, runs them against real datasets and explains what it found — served by FastAPI on Azure with Redis for caching and sessions.

DatavioDevOps

Versioned blue-green deploys

Ship any time — even while long workflows are running.

Each release boots as its own Docker Compose project, passes a health gate, and takes new traffic through a graceful nginx reload. Older versions keep draining in-flight work, then a janitor reaps them.

Penny-level reconciliation

Every payment explained, down to the paisa.

Channels pay brands in lumpy transfers, net of debit notes, TDS and charges. The engine traces every UTR to the invoices it settled — and every invoice to each rupee that settled it — across POs, GRNs, invoices, debit notes and payment reports.

SME Agent

Question papers in, question bank out — with a human in the loop.

A LangGraph agent that parses papers, builds question payloads and syncs Drive, Excel and a question-bank API — pausing for review and resuming any time from SQLite checkpoints.

Queue-driven data pipeline

Queue it, fan it out, stop blocking the app.

Django APIs enqueue work on AWS SQS; Lambda functions process it in parallel with S3 in between — so heavy jobs never hold up user-facing requests.
