I am an ACM-ICPC World Finalist and software engineer. I have been developing backend and DevOps solutions using C++, Java, and Python since 2016. I have experience in multiple domains that include fintech, agrotech, health tech, IoT, and Saas. I have been working as a remote developer with globally distributed teams since 2019. I am a quick learner, good with communication, proactive and punctual human being. Nothing excites more me than a challenge that is necessary but difficult to solve. I am also a competitive programmer and expert in data structures and algorithms. I have a decent understanding of UNIX systems especially how different types of data structures are blended to solve complex problems of operating systems. I am a team player and can work as solo as well. I never compromise the quality of my work doesn't matter how the pressure is. And, I believe in requirement analysis as the most crucial part of engagement.

Hello! Mostafa Mir Kashem here! I'm a virtual assistant who does the admin and data work most VAs do by hand, faster, because I automate it. Spreadsheets that would take hours to clean, CRM imports, repetitive data tasks: I use Excel, Google Sheets, and Python to get them done accurately and give you your time back. Over the past two years, I've built CRM import files from scattered records, cleaned and structured large spreadsheets, and set up reporting that makes the numbers usable. Virtual assistant & admin support ✅ Inbox and calendar management, file organization, online research ✅ Document formatting and process documentation ✅ Customer service: inquiries, support email, live chat ✅ Social media support: scheduling, light content, basic reporting Data entry & data management ✅ Accurate data entry, cleansing, validation, and organization at high volume ✅ Excel and Google Sheets: spreadsheets, databases, reports, formulas ✅ CRM data work, including Zoho: deduplication and import-ready formatting ✅ Spreadsheet automation with Python (openpyxl) for cleanup that would take hours by hand, so you pay for the result, not the busywork Video editing ✅ Premiere Pro, Final Cut Pro, and DaVinci Resolve ✅ Color correction, audio cleanup, motion graphics, cuts for pacing ✅ Corporate videos, promos, and social clips I'm finishing a Computer Science degree, so the technical side (automation, clean data structures, tools that scale) comes naturally. I respond quickly, I ask clarifying questions before I start, and I deliver what I said I would. Send me a note describing what you need, and I'll tell you honestly whether I'm the right fit.

I am a competitive programmer who likes to code in C/C++, Java, and python. I have a strong background in Data Structure Algorithms, Cryptography. My communication and writing skill is also good. I graduated recently in Computer Science.

When Meta reports 450 conversions but Shopify processed 680 orders, your ad algorithms are targeting the wrong audiences with the wrong budgets. Your ROAS is a lie. And your ad spend is quietly bleeding. Browser-based tracking is broken in 2026. Apple's Safari & iOS privacy, ad blockers, and cookie deprecation silently destroy 20-40% of your conversion signals before they reach Meta, Google, or TikTok. Standard pixel installs cannot fix this. I am a shopify expert in architecting server-side conversion tracking, first-party data tracking, and attribution infrastructure for D2C and B2B eCommerce brands running paid ads on Meta, Google, TikTok, and Pinterest across Shopify, Shopify Plus, and mobile app channels. This is not a tag installation. This is data engineering for ad performance. ## 𝗪𝗛𝗘𝗡 𝗕𝗥𝗔𝗡𝗗𝗦 𝗛𝗜𝗥𝗘 𝗠𝗘 - Meta Event Match Quality stuck at Poor or OK despite having CAPI installed - Google Ads Enhanced Conversions not matching actual Shopify orders - Tracking broke after a Shopify theme update or checkout extensibility migration - Launching a mobile app alongside Shopify and need unified web-to-app attribution via AppsFlyer - Expanding to TikTok, Pinterest, or Snapchat and need Conversions APIs built from scratch - Need monthly attribution reporting that reconciles platform ROAS against actual Shopify revenue - Previous specialist set it up but cannot debug custom data layers, consent-conditional payloads, or server-side template logic - Consent Mode v2 not configured correctly and EU traffic is skewing GA4 and Google Ads data - Duplicate or missing purchase events causing over-reporting or under-reporting in ad platforms ## 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 - 𝙎𝙚𝙧𝙫𝙚𝙧-𝙎𝙞𝙙𝙚 𝙏𝙧𝙖𝙘𝙠𝙞𝙣𝙜: GTM, sGTM via Stape (container provisioning, custom domain, first-party cookies). Meta CAPI with event deduplication. Google Ads Enhanced Conversions with first-party data hashing. TikTok Events API, Pinterest CAPI, Snapchat CAPI, Microsoft UET, LinkedIn API, Microsoft Ads, Call Tracking Platforms, and offline CRM uploads. Custom sGTM tag templates. Triple Whale, Elevar, Hyros, Cometly, Northbeam, RedTrack. - 𝙎𝙝𝙤𝙥𝙞𝙛𝙮 𝘼𝙧𝙘𝙝𝙞𝙩𝙚𝙘𝙩𝙪𝙧𝙚: Custom data layer in Liquid and JavaScript. Shopify Customer Events API for post-checkout tracking. Checkout extensibility for Shopify Plus. Cross-domain and cross-storefront tracking. Headless Shopify (Hydrogen) event architecture. - 𝘼𝙩𝙩𝙧𝙞𝙗𝙪𝙩𝙞𝙤𝙣 𝙖𝙣𝙙 𝘼𝙣𝙖𝙡𝙮𝙩𝙞𝙘𝙨: GA4 enhanced eCommerce, purchase accuracy, full funnel, custom dimensions. BigQuery SQL for raw event analysis. Looker Studio dashboards: ROAS by channel, CAC, LTV cohorts. Mixpanel, Amplitude, PostHog, Segment. Automated anomaly detection via n8n. Monthly platform vs Shopify revenue reconciliation. - 𝙈𝙤𝙗𝙞𝙡𝙚 𝘼𝙩𝙩𝙧𝙞𝙗𝙪𝙩𝙞𝙤𝙣: AppsFlyer SDK for iOS and Android. Web-to-app attribution across ad click, install, and in-app purchase. Cross-platform identity resolution between GA4 and AppsFlyer. RevenueCat for subscription tracking. - 𝘾𝙤𝙣𝙨𝙚𝙣𝙩 𝙖𝙣𝙙 𝙋𝙧𝙞𝙫𝙖𝙘𝙮: Google Consent Mode v2. Cookiebot, CookieYes, OneTrust, Iubenda integration. Server-side PII hashing for Google, Meta, and TikTok. GDPR and CCPA compliant architecture. - 𝘾𝙍𝙊 𝙖𝙣𝙙 𝙄𝙣𝙨𝙞𝙜𝙝𝙩𝙨: Hotjar, Microsoft Clarity, VWO, Optimizely, Klaviyo, HubSpot, Salesforce. A/B testing infrastructure. Shopify CRO backed by 7+ years of web development experience. ## 𝗢𝗡𝗚𝗢𝗜𝗡𝗚 𝗠𝗢𝗡𝗜𝗧𝗢𝗥𝗜𝗡𝗚 Tracking degrades silently. Theme updates break data layers. Platform API versions change event schemas. App updates shift SDK behavior. Most brands only notice when ROAS tanks. Monthly retainer clients get proactive signal health monitoring across all platforms, Event Match Quality tracking and optimization, automated anomaly alerts before revenue is impacted, and onboarding support for new ad channels as the mix evolves. ## 𝗧𝗢𝗢𝗟𝗦 sGTM, Stape, Meta CAPI, GA4, BigQuery, Looker Studio, Google Ads Enhanced Conversions, TikTok Events API, Pinterest CAPI, Shopify, Shopify Plus, Shopify Customer Events API, Checkout Extensibility, Headless Shopify, AppsFlyer, Triple Whale, Elevar, Northbeam, Hyros, Cometly, RedTrack, Klaviyo, Mixpanel, Amplitude, PostHog, Segment, n8n, GCM v2, Cookiebot, OneTrust, HubSpot, Salesforce, VWO, Hotjar, Microsoft Clarity, Snowflake, Optimizely
