Prasanna Kumar Das

Professional Summary

14 years of MIS experience. Two years going deep on AI.

Management Information Systems (MIS) and Data Analytics professional with 14 years of Telecom experience, now transitioning into AI Automation and Workflow Engineering. Over the past two years I've self-trained intensively in this field and built hands-on, self-initiated projects — AI agents, AI chatbots, and multi-step n8n and Make workflows that connect CRMs, databases, and business tools through REST APIs and webhooks to automate lead management, customer support, reporting, and content operations.

I'm comfortable working with OpenAI, Claude, and Gemini APIs, prompt engineering, Airtable data models, error handling, and workflow documentation — and I keep deepening these skills through practical builds. My MIS background brings genuine strength in process mapping, data quality, and business reporting: understanding which process is worth automating and how to measure the result.

I'm seeking my first professional role in AI Automation and Workflow Engineering — or freelance and contract projects where I can apply this hands-on experience — and grow quickly within a team.

Process-First

I map and re-engineer the manual process before automating it — targeting the highest-effort, highest-error steps first.

Reliability by Design

Error handling, retries, deduplication, validation, and Telegram failure alerts built into every workflow.

Human-in-the-Loop

Inline approval steps for AI-drafted actions, so nothing ships without review where judgment matters.

Documented Handover

Every workflow ships with documentation so the team can run, monitor, and extend it independently.

Career

Professional Experience

Fourteen years of MIS & data analytics, plus two years building AI automation hands-on.

AI Automation & Workflow Engineer2024 – Present

Independent Practice

Design and build hands-on AI automation workflows using n8n and Make, integrating CRMs, databases, email, messaging, and web applications.
Develop AI agents and AI chatbots on OpenAI, Claude, and Gemini APIs, applying prompt engineering, tool calling, and structured JSON outputs to automate lead qualification, customer support, and business research.
Integrate systems through REST APIs and webhooks with API authentication, data mapping, pagination, and JSON/data transformation between services.
Build knowledge-base-driven AI agents and RAG pipelines using Airtable and Supabase, along with embeddings and Postgres/pgvector, to keep responses grounded in business-specific information.
Engineer reliability with error handling, retries, conditional branching, deduplication, validation, and logging, plus Telegram failure alerts for visibility.
Design human-in-the-loop approval steps (inline Telegram approval cards) so AI-drafted actions are reviewed before anything is sent.
Map and re-engineer manual business processes before automating, replacing the highest-effort, highest-error steps with automated, auditable flows.
Document workflows and hand over operating instructions so business users can run, monitor, and extend the automations independently.

My Work

Key Projects

Real, hands-on AI automation and data analytics builds — not demos.

AI Agents & Automation

CRM AI Agent — Outreach & Follow-Up

A two-agent CRM automation with autonomous decision-making. A daily outreach agent pulls new and follow-up-due leads from Airtable, researches each company, and independently decides whether to send a personalised cold email or skip a low-confidence lead. A second agent checks Gmail every four hours, reads replies for actual intent, and escalates to a human via Telegram only when judgment is genuinely needed.

n8nLLM Tool-Calling AgentsAirtableGmail APIGoogle Search / MapsTelegram Bot API

📈 Both agents update lead status, notes, and follow-up dates in Airtable after every action — the lead lifecycle runs end to end with human input only where it's needed.

Enterprise Knowledge Base RAG and AI Support Agent n8n workflow

Enterprise Knowledge Base RAG & AI Support Agent

A two-workflow RAG system: an ingestion pipeline that chunks, embeds, and stores company documents in a Postgres vector database with document-level idempotency, and a Q&A pipeline that retrieves top-K relevant chunks, validates retrieval sufficiency, and produces answers grounded strictly in retrieved context.

n8nEmbeddingsPostgres / pgvectorLLM APIsTelegram Bot API

📈 Hard fallback to human escalation via Telegram when the knowledge base doesn't cover a question, rather than letting the model guess.

AI Lead Generation Automation

A B2B lead qualification engine scanning five public signal sources — job boards and Hacker News discussions — for businesses showing real operational automation pain. A keyword pre-filter runs before any AI call, then a two-stage Gemini pipeline scores each lead against a 7-factor, 100-point rubric, with a second "skeptical auditor" model able to veto the verdict.

n8nGemini APIMulti-Stage LLM EvaluationREST APIsAirtable

📈 Only leads surviving both AI passes are enriched and written to the CRM, cutting false positives before they reach a human.

AI Email Classification and Auto-Reply n8n workflow

AI Email Classification & Auto-Reply Workflow

An AI email triage system that classifies every incoming email into three tiers — promotional (auto-archived), important (Telegram FYI), or needs-reply (drafted and routed for approval) — using a Gemini agent constrained to strict JSON output, with a one-tap Telegram approval card dispatching the reply via Gmail.

n8nGemini APIStructured JSON OutputGmail APITelegram Bot API

📈 Removes inbox triage entirely while keeping a human decision point on every email that genuinely needs one.

Multi-Tenant WhatsApp AI Agent

A multi-tenant n8n workflow supporting multiple WhatsApp clients without separate deployments. Incoming messages resolve to a client by WhatsApp number, dynamically pulling that client's system prompt and knowledge base from Supabase at runtime — answering strictly from the client's own data.

n8nGemini APISupabaseWhatsApp Business API

📈 A composite session key (client + customer) keeps conversation memory fully isolated per tenant, scaling to new clients through configuration alone.

RSS Social Media Post Automation

A fully automated content pipeline that monitors RSS feeds, rewrites content using an LLM chain, and publishes simultaneously to Instagram, LinkedIn, and Facebook — with images and comments — zero manual work required.

n8nRSS FeedLLM ChainLinkedIn APIInstagramFacebook

📈 Publishes 5–10 posts daily across 3 platforms with zero manual effort.

Data Analytics & BI

AI-Assisted Power BI Sales Dashboard

A comprehensive Power BI dashboard built with AI assistance — covering Total Sales, Cost, Profit, and regional breakdowns across segments and sub-categories. AI was used to structure the data model, generate DAX measures, and recommend the most insightful visualisations.
