Data Analyst & Digital Marketer turning raw numbers into business decisions — using Python, SQL, Power BI, Tableau & Excel.
SERVICES &
EXPERTISE
Combining data analytics with digital marketing to deliver measurable results and strategic insights.
Data Analysis
Transform complex datasets into clear, actionable insights using Python, SQL, and advanced Excel modelling. From cleaning messy raw data to building predictive models, I help organisations understand what their numbers actually mean and what actions to take next. Every analysis is delivered with clear documentation and business-friendly summaries.
Dashboard Development
Build interactive, real-time dashboards in Power BI and Tableau that empower data-driven decisions across teams. I design dashboards that are intuitive enough for non-technical stakeholders yet powerful enough to reveal deep patterns. Custom KPIs, drill-down filters, and automated data refresh come as standard in every dashboard I deliver.
Digital Marketing
Full-spectrum digital marketing strategy including SEO, content marketing, PPC management, and analytics integration for measurable, sustainable growth. I audit existing marketing channels, identify quick wins and long-term opportunities, then build and execute strategies that attract the right audience and convert them into loyal customers.
Marketing Analytics
Measure ROI accurately, attribute campaigns to real conversions, and optimise performance using GA4, Google Search Console, Facebook Ads Manager, and custom reporting pipelines. I connect marketing spend directly to business outcomes so you always know which channels deserve more budget and which ones to cut.
WHO
I AM
I'm Shayantha Das, a Data Analyst and Digital Marketer based in Chattogram, Bangladesh. I specialize in extracting meaningful stories from data and using those insights to drive marketing strategies that actually work.
With hands-on experience across Python, SQL, Power BI, Tableau, and advanced Excel, I bridge the gap between raw data and business outcomes. On the marketing side, I combine SEO, content strategy, and performance analytics to grow online presence both organically and through paid channels.
My goal is simple: help businesses make smarter, faster decisions backed by real evidence — not guesswork.
I have worked with e-commerce brands, logistics companies, and digital agencies in Bangladesh and internationally, delivering dashboards, automated reports, and growth campaigns that produce measurable outcomes. Whether you need a one-off analysis or an ongoing analytics partnership, I bring the same level of care and precision to every engagement.

WHY WORK
WITH ME
I combine technical depth with clear communication — so insights actually reach the people who need them.
Business-First Thinking
Every analysis starts with a business question, not a dataset. I focus on the decisions your organisation needs to make and work backwards to the data and tools required. This keeps projects lean, relevant, and fast to deliver tangible value.
Fast Turnaround
Based in Chattogram with a flexible schedule, I respond to messages within hours and deliver first drafts faster than most agencies. Urgent data requests, last-minute campaign analysis, or emergency dashboard fixes — I have consistently met tight deadlines without compromising quality.
Transparent Process
You will always know what I am working on, why I made certain decisions, and what the results mean. I document every project thoroughly, write plain-English summaries alongside technical reports, and never hide behind jargon. My clients understand their own data better after working with me.
Continuous Learning
The data and marketing landscape evolves rapidly. I dedicate time every week to learning new techniques, tools, and frameworks — from the latest GA4 features and Power BI updates to emerging machine learning libraries. Your projects always benefit from current best practices rather than outdated approaches.
Long-Term Partnership
Most of my clients return for repeat projects because I invest in understanding their business deeply over time. I maintain documentation, version control, and handover materials so nothing is lost between engagements. Whether you need a one-off analysis or an ongoing analytics retainer, I am equally committed to your success.
Competitive Rates
Flexible pricing that suits startups, SMEs, and larger organisations alike. Fixed-price packages for defined deliverables, hourly rates for exploratory analysis, and monthly retainers for ongoing support. Transparent quotes with no hidden fees — you always know exactly what you are paying for and why it is worth it.
MY PROCESS
A clear, repeatable process that delivers consistent results on every project.
