I am experienced and results-driven business intelligence and consumer insights professional with an entrepreneurial foundation rooted in the retail industry. My 8+ years experience started while attending Purdue University, I launched a consulting business focused on identifying consumer trends, improving customer experience, and helping brands build stronger loyalty and retention strategies. That early experience shaped a data-driven and customer-centric approach that I later applied across additional industries through consulting and agency roles after graduation. Throughout positions at BDS Connected Solutions, Daymark Consulting, and Neptune Retail Solutions, I have leveraged quantitative and qualitative research, syndicated data, SQL, Tableau, Circana, and stakeholder collaboration to drive strategic decision-making, improve operational performance, and uncover growth opportunities across the retail, CPG, hospitality, and automotive sectors. Recognized for combining analytical expertise with strong communication and leadership skills, I bring a track record of creating business value, supporting high-performing teams, and translating market intelligence into actionable business strategies.

As a Sociologist with over 9 years of international experience, I specialize in bridging the gap between raw data and strategic decision-making. I provide a comprehensive approach to data, managing the entire lifecycle: from advanced Excel data cleaning to deep-dive qualitative and quantitative analysis in SPSS, ATLAS.ti, and MAXQDA.
My methodology ensures that every project—whether a national household survey or a sensitive social impact assessment—is delivered with methodological rigor and executive clarity.
Core Competencies:
Data Management & Excel: Advanced data cleaning, complex variable calculation, and dataset organization. I transform unstructured spreadsheets into analysis-ready databases, creating professional visualizations and dynamic tables that communicate results.
Quantitative Analysis: High-complexity data processing using SPSS. I developed the syntax architecture for a National Household Survey (N=165,000), establishing technical standards for cleaning and analyzing massive datasets.
Qualitative Analysis: Using ATLAS.ti and MAXQDA, I transform unstructured text (interviews, focus groups, open-ended surveys) into robust thematic maps and semantic networks. I have executed social due diligence projects for international consultancy firms, identifying critical risks and mitigation strategies.
Multisectoral Focus: Background in Gender Equity, Education, Public Health, and Infrastructure. I apply a social-inclusion lens to deliver insights tailored to specific goals, from policy-making to community development.
Technical Toolkit
Advanced Excel: Data Cleaning, Pivot Tables, and Complex Formulas.
Quantitative: SPSS (Syntax, Descriptives, Crosstabs, Data Cleaning).
Qualitative: ATLAS.ti, MAXQDA (Thematic Analysis, Semantic Network Mapping, Hybrid Coding, Discpurse Analysis).
Reporting: Actionable insights for Government, NGOs, and International Stakeholders.
I am recognized for my autonomy and ability to meet tight deadlines, delivering results that move beyond simple charts to reveal the evidence-based story behind the data.

I help businesses get their operations out of people's heads and into systems that actually work — through SOPs, process maps, and workflow documentation that stick.
My background includes pharmacy benefits analytics at Xevant and enterprise healthcare data work at Change Healthcare — which means I understand operations at a level most freelancers don’t. I’m also currently engaged as a Business Analyst on a large-scale enterprise consulting project (details under NDA), leading discovery, risk and bottleneck analysis, process improvement, and user story development — so this isn’t just past experience, it’s live, current work.
I help businesses fix both sides of the problem: building clean data systems and the process documentation to make them actually stick.
What I help with:
— SOPs and workflow documentation
— Process mapping and bottleneck analysis (Lucidchart)
— Workflow audits with prioritized recommendations
— Excel & Access dashboards, trackers, and databases
— Cross-functional coordination and operational reporting
I offer fixed-price catalog projects for SOPs, workflow audits, and operations starter packs — so you know exactly what you're getting before we start.
I work fast, communicate clearly, and deliver things that get used. Based in Maine, available across US time zones.
If that's what you need — let's talk.

🇪🇺 EU Marketplace Feed Specialist | Channable & BaseLinker Certified
🚀 I help brands go live and sell across European marketplaces - turning rejected products into approved, synced, revenue-ready listings.
⭐ Top Rated on Upwork | 2,600+ hours | 93% Job Success | 5-star reviews across
If you're launching on Mirakl-powered marketplaces, bol, Decathlon, eMAG, Fashion Days, Allegro, eMag or Kaufland and your products are stuck in rejections, attribute errors, or feed failures, that's exactly what I fix.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔹 𝐖𝐡𝐚𝐭 𝐈 𝐂𝐚𝐧 𝐇𝐞𝐥𝐩 𝐘𝐨𝐮 𝐖𝐢𝐭𝐡:

◆ Channable & BaseLinker Feed Integration - Connect Shopify, WooCommerce, Magento, PrestaShop or Odoo ERP to any EU marketplace
◆ Category & Attribute Mapping - Align product data to each marketplace's exact taxonomy so listings pass validation the first time

◆ Google Shopping Feeds - Build & optimize Google Merchant Center feeds through Channable for approved, ad-ready listings
◆ Inventory & Order Sync - Keep stock, pricing, and orders accurate across every connected channel

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🤝 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐓𝐫𝐮𝐬𝐭 𝐌𝐞:
Most feed and marketplace work goes wrong for one reason: no clear system and poor communication. Here's how I keep your project on track:
◆ Root-cause fixes, not band-aids - I find why products are rejecting so the errors don't come back next week
◆ Clear scope from day one - We agree exactly what's being delivered before I start, so no surprises
◆ Regular progress updates - Daily or weekly, your choice, so you always know where things stand
◆ Built to scale - I structure feeds for accuracy and growth, not quick fixes that break at higher volume

Both - one-time catalog onboarding and error fixes, plus ongoing feed management and marketplace maintenance.
