01

Context

Two decades inside boardrooms, plant offices and virtual classrooms — teaching the tools that decide how quickly work actually gets done.

I work with organisations that already own the software but are not yet getting the return. The gap is rarely the licence — it is the habit. Programmes are rebuilt around the client’s own reporting files so that what is practised on day one is used on day two.

Since 2023 every programme carries a generative-AI layer: ChatGPT, Gemini, Claude and Microsoft Copilot applied to the same spreadsheets, decks and inboxes the team already works in — with clear guardrails on what should never be pasted into a model.

02

Programmes

Six core programmes, each modular and re-cut to the cohort’s level and reporting reality.

01

Advanced Excel & Data Analysis

From clean data structures to nested logic, dynamic arrays and error-proof models used in live reporting.

02

Power Query, Power Pivot & Dashboards

Turn repetitive monthly reporting into a refresh button. ETL, data models, DAX measures and executive dashboards.

03

Power BI for Business Reporting

End-to-end Power BI: connect, shape, model and publish reports the leadership team actually opens.

04

Generative AI for the Workplace

ChatGPT, Gemini, Claude and Microsoft Copilot applied to real office work — prompts, drafting, analysis and guardrails.

All six programmes

03

Method

Four stages, applied to every engagement regardless of length.

01

Diagnose

A pre-programme conversation and skills check to find where the real time is lost — not where the syllabus says it should be.

02

Contextualise

Exercises are rebuilt around the client's own files, formats and reporting cycles, so day-one transfer is possible.

03

Practise

Hands-on, keyboard-on-desk sessions. Concepts are demonstrated, then repeated by every participant.

04

Embed

Job aids, recorded walkthroughs and a follow-up window so the learning survives the week after the workshop.

04

Delivery

Formats built around how the team is actually distributed.

In-person workshops

Classroom or plant-floor sessions across India, with equipment and dataset setup handled in advance.

Live virtual cohorts

Teams / Zoom delivery with breakout practice, screen-share reviews and recorded modules.

Blended programmes

Virtual foundation followed by an in-person application lab for larger, multi-location teams.

Executive briefings

Short, sharp sessions for leadership on AI adoption and data-led decision making.

05

Advanced Excel — TMILL + Peerless, Nov 2025

A sample from recent cohorts — one representative feedback set out of hundreds collected across 120+ corporate trainings.

The session was extremely well structured. Complex Excel functions were broken down so clearly that we could apply them to live work files the same week.

Assistant Manager

TMILL · Advanced Excel, Nov 2025

Patient, approachable and never rushed. Every question was answered until the whole room understood it.

Officer

The Peerless General Finance & Investment Co. · Advanced Excel, Nov 2025

Bringing AI and Copilot into an Excel programme made it immediately relevant — this is how our office actually works now.

Sr. Manager

TMILL · Advanced Excel, Nov 2025

Excellent command over the subject. The Power Query and dashboard modules alone saved hours of our monthly reporting.
