Career Journey

The lessons behind each stage.

01 · Engineering

Taught the habit of finding root causes instead of treating symptoms — a lens that still shapes every audit.

02 · Trading

Taught that being right on average means nothing if you can't survive being wrong in the short term.

03 · Photography

Sharpened an eye for what actually makes someone stop and pay attention.

04 · Digital Marketing

Where engineering, risk, and attention converged into SEO and paid media that actually performs.

05 · Marketing Analytics

Replaced instinct with a scoreboard — a way to know, not guess, whether something is working.

06 · AI & Automation

Freed up time from mechanical work so more of it could go toward judgment calls.

07 · Founder

Built Anextera Technologies around a simple bet: data beats assumptions, almost every time.

08 · Director

Took on New India Social Welfare Foundation — the same operating discipline, a different kind of return.

Areas of Expertise

What I bring to the table.

SEO

Search visibility built on how ranking actually works today, not outdated tactics.

Technical SEO

Fixing crawlability and indexability issues that keep good content from ever being found.

AEO

Structuring content to be lifted cleanly into AI-generated answers, not just search snippets.

GEO

Earning citation inside generative AI summaries as search shifts away from ten blue links.

Google Ads

Search, Shopping, and Performance Max accounts structured for signal quality, not just spend.

Performance Marketing

Full-funnel campaigns judged on CAC and LTV, not impressions.

LinkedIn Ads

B2B campaigns built around the accounts and titles that actually convert.

Meta Ads

Creative and targeting tuned for a platform where attention is expensive and short.

HubSpot CRM

Pipelines that reflect how deals actually move, not how a template assumes they do.

Marketing Analytics

Dashboards and attribution that tell you what's working before the budget is spent.

Conversion Optimisation

Removing friction between interest and action, tested rather than assumed.

Marketing Automation

Workflows that remove repetitive work without removing a human from the decision.

AI Workflows

AI applied to the mechanical parts of marketing ops — reporting, briefs, QA — not the judgment calls.

Prompt Engineering

Getting consistent, usable output from AI tools instead of one-off lucky prompts.

Website Strategy

Information architecture and conversion paths decided before any visual design happens.

Growth Strategy

Go-to-market and positioning for founders who need a growth plan, not just a content calendar.

Business Analytics

Reporting frameworks built around the metrics leadership actually needs to decide.

Industries Served

Different industries, the same discipline.

Healthcare

Trust-heavy decisions need compliant, credible marketing — not aggressive acquisition tactics.

Education

Long consideration cycles need nurture sequences, not one-touch conversion pressure.

Technology

Technical buyers see through fluff fast — positioning has to be precise, not just polished.

E-commerce

Margin pressure means every channel has to earn its CAC, not just its impressions.

Manufacturing

Long sales cycles and technical buyers reward patient, credibility-first content.

Export

Cross-border trust and discoverability matter as much as the product itself.

B2B

Multiple stakeholders in every deal mean marketing has to speak to more than one buyer at once.

NGOs

Impact has to be communicated as clearly as it's delivered — donors fund clarity, not just cause.
