Hire the Best ZIK-Analytics Professionals

If you have business data that needs to make sense, dashboards that need to work, and systems your team can rely on, you're in the right place. With 5+ years in data and revenue analytics, plus a background in accounting, I work across the full picture: understanding what your business actually needs, cleaning and analyzing the data, and building reporting and systems that are genuinely useful, not just nice to look at. My background is specifically in revenue management & operations, so I don't just report numbers, I look for what actually moves them. Every system I build is with an eye toward what increases revenue or reduces cost, not just what looks clean on a dashboard. What sets me apart: Most analysts can clean data or build a dashboard. I do the whole pipeline, and I understand the financial logic behind your numbers, not just how to visualize them. I also use AI tools like Claude to work faster and dig deeper, so you get better results in less time. The thinking and final output are always mine. What I can help with: ✔ Data cleaning — structuring messy datasets so your reporting is reliable (SQL, Power Query, Excel, from 470 rows to 1M+ records) ✔ Analysis & insights — surfacing what actually moves the needle for your business ✔ Dashboards — Power BI, Looker Studio, Google Sheets, with financial summaries your stakeholders can act on ✔ Systems & automation — calculators, trackers, Gantt charts, and automated workflows in Excel and Sheets A few things I've built: ✅ The full financial and operational foundation for a product line that scaled to $3M in quarterly revenue ✅ Dashboards across a 300+ hotel portfolio worth $100M+, including margin tracking and cash flow modeling ✅ Reporting and automated systems for clients across the US, UK, and UAE Tools Excel · Google Sheets · SQL · Python · Power BI · Tableau · DOMO · Google Apps Script · PowerPoint I like to understand the real problem before jumping to solutions. If that sounds like a fit, tell me a bit about your project and let's talk!

Great dashboards don’t just show numbers; they tell a story your team can act on. I design dashboards in Looker Studio Pro and BI tools that unify marketing, product, and financial data into one clear source of truth.

Ad algorithms are only as good as the data you feed them. Let's skip the fluff: most brands burn their marketing budgets scaling campaigns on broken browser pixels and flawed attribution. TL;DR: I fix your data foundation first, then I scale your ad campaigns. Over the last 6+ years of managing high-spend ad accounts and digital infrastructure in-house, I realized that you simply cannot scale revenue on a broken tracking setup. I bridge the gap between Data Engineering and Performance Marketing. I build immutable server-side data pipelines and use those clean signals to drive aggressive, profitable ad campaigns. I specialize in two core pillars: 1. Data Infrastructure & Attribution (Stopping the Leaks) Browser-only tracking is practically dead. I engineer robust solutions that bypass iOS restrictions, ad-blockers, and cross-domain data leaks so you never fly blind. Server-Side Architectures: Deploying sGTM (via Stape or GCP) and Conversions API (CAPI) for multiple networks. Complex E-commerce & SPAs: Deep integration for Shopify (including Checkout Extensibility and backend subscription webhooks) and resolving OAuth referral overwrites in Single Page Applications (Nuxt, Webflow). Compliance & Accuracy: Flawless Consent Mode v2 configurations and deduplication logic to ensure 100% accurate first-touch attribution. 2. Performance Marketing (The Execution) I don't just route data; I know how to make ad platforms leverage it. Clean server signals allow me to push the algorithms further. Google Ads: Architecting highly segmented Search, Shopping, and Performance Max campaigns built on offline conversion imports. Multi-Channel Acquisition: Scaling paid media pipelines across Meta, LinkedIn, TikTok, Pinterest, Snapchat, and Amazon using high event match quality and precise server-side signals. Custom Analytics & BI: Building bespoke, interactive reporting pipelines and data visualization dashboards. No vanity metrics—just the true numbers that dictate your profit. My Engineering Standard I operate 100% asynchronously via text. This is a deliberate standard: it guarantees zero calendar friction, no wasted time on endless Zoom calls, and ensures that every technical configuration or campaign adjustment is explicitly documented in writing. If your tracking is bleeding data or your ad campaigns have hit a wall, send me a quick breakdown of your current setup, and let's map out a pragmatic fix.

4+ years building BI end-to-end Infrastructure. I sit with the ambiguity, ask what your team hasn't, and translate fuzzy business goals into a clear data model and KPI framework that holds up under scrutiny. 🧠 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐫𝐢𝐧𝐠 𝐭𝐨 𝐲𝐨𝐮𝐫 𝐭𝐞𝐚𝐦 🔹 Ambiguity → Clarity: I define the right questions and metrics before building anything, so you measure what matters, not what's easy. 🔹 Semantic & Data Modeling: Star schemas, slowly-changing dimensions, reconciled grain, single source of truth 🔹 Scalable Architecture: Pipelines and models designed for "Day 2", maintainable, cost-aware, documented, built to grow instead of breaking at scale. 🔹 Context Integration: I unify Stripe, Shopify, Zoho, GA4, Ads platforms, etc. and CRMs into one coherent ecosystem that mirrors how your business actually operates. 🔹 Narrative & Decision Design: Every visual answers a business question and points to an action, analysis a CEO can act on in seconds. ⚙️ 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗧𝗼𝗼𝗹𝗯𝗼𝘅 🔹 BI & Viz: Power BI, Looker Studio, Zoho Analytics, Metabase, Apache Superset, Domo, Databox 🔹 Modeling & Query: SQL, DAX, Power Query (M), Python, dbt, Excel 🔹 Warehousing: BigQuery, Cloud SQL, Snowflake, SQL Server, MySQL, Firebase 🔹 Pipelines & ETL: Make, n8n, Fivetran, Apps Script, Cloud Run, Windsor AI, Coupler IO, Supermetrics 🔹 Sources: Stripe, Shopify, Zoho CRM, GA4, Google/Meta/TikTok Ads, Search Console, etc. 🔹 AI layer (the plus): OpenAI & Claude APIs, Claude Code, Codex, conversational analytics, anomaly detection, predictive models, and agent workflows for automated briefings & alerts 🚀 𝗪𝗵𝗮𝘁 𝗦𝗲𝘁𝘀 𝗠𝗲 𝗔𝗽𝗮𝗿𝘁 🔹 Business-first, not tool-first: I start with your objectives and constraints, not your dataset. 🔹 End-to-end ownership: From auditing sources and defining KPIs to modeling, building, and publishing, I run the full lifecycle. 🔹 Transparency: You own your data and infrastructure. I document every step, so nothing is a black box. 🔹 AI as leverage, not a gimmick: I automate the repetitive parts so the strategic parts get more of my attention. ⭐ 𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗦𝘁𝗮𝘆 🔹 Reliable communication and clear expectations , no micromanagement needed. 🔹 Insights in plain language, for technical and non-technical stakeholders alike. 🔹 Proactive: I diagnose and recommend, not just deliver charts. 🔹 Consistent delivery, on time, with care. 💡 𝗟𝗲𝘁'𝘀 𝗕𝘂𝗶𝗹𝗱 𝗬𝗼𝘂𝗿 𝗗𝗲𝗰𝗶𝘀𝗶𝗼𝗻 𝗦𝘆𝘀𝘁𝗲𝗺 If your business generates data but not clarity, let's fix that.
