Project details
Slow or failing SQL queries can disrupt operations, increase costs, and frustrate teams. I help you quickly diagnose, debug, and optimize SQL queries so your database is fast, reliable, and easy to maintain.
Whether you're dealing with errors, long-running queries, inefficient joins, missing indexes, or confusing execution plans, I follow a structured, professional workflow to identify the root cause and deliver actionable fixes.
I support MySQL, PostgreSQL, MS SQL Server, and SQLite. My specialties include:
• Fixing errors and broken queries
• Improving query speed and efficiency
• Rewriting complex SQL for clarity and performance
• Execution plan analysis
• Indexing recommendations
• Identifying bottlenecks in joins, filters, and aggregations
Each package provides a clear, fixed scope and fast turnaround, so you always know exactly what you're getting. You’ll receive optimized SQL along with clear explanations of what was improved and why.

Google Ads & GA4 E-Commerce Tracking Specialist
About Mohd Hammad
GA4 Server-Side & Meta CAPI Consultant | Recover Lost Conversions
New Delhi, India - 3:00 pm local time
If your tags rely entirely on browser cookies, Safari’s ITP restrictions (which delete tracking cookies in 1 to 7 days) and ad blockers are likely hiding 40% to 60% of your actual conversions. Your campaigns are converting, but your ad algorithms (Google Ads, Meta) are optimizing blind.
I build resilient server-side tracking pipelines that recover lost conversions, deduplicate events, and feed clean first-party data directly to your ad platforms and reporting dashboards.
🎯 HOW I HELP MEDIA AGENCIES & GROWTH BRANDS:
1. Server-Side GTM & Conversions API (CAPI): Set up first-party subdomains on GCP or Stape to bypass ad-blockers and extend cookie lifespans to 1-2 years.
2. Consent Mode v2 & GDPR Compliance: Integrate Google-certified CMPs (OneTrust, Cookiebot) with GTM to pass required consent flags (ad_user_data, ad_personalization) without breaking conversion signals.
3. Marketing Analytics Pipelines: Flatten GA4 BigQuery raw event exports, apply custom Last Non-Direct Click attribution logic, and automate reports to Looker Studio. No more API quotas or slow dashboards.
4. E-commerce & Lead Gen Tracking: Build clean GTM data layers tailored to your vertical, whether that's real-time purchase matching for Shopify or routing offline CRM pipeline stages back to ad platforms for B2B.
📊 CASE STUDY: Stopping a Five-Figure Monthly Ad Bleed
During a recent Shopify tracking audit, I discovered a duplicate tracking setup: a hardcoded GA4 script in theme.liquid was firing alongside client-side GTM. This inflated reported purchases by 40%, feeding Google Ads duplicate conversion signals and causing artificial bid inflation.
I migrated all tracking to a deduplicated Server-Side GTM container, verified event match quality, and stopped a multi-thousand dollar monthly ad leak.
🛠️ THE MODERN ATTRIBUTION STACK:
• Tagging: Google Tag Manager (Web & Server-Side), Stape, Google Cloud Run
• Destinations: Google Analytics 4 (GA4), Meta CAPI, Google Ads Enhanced Conversions, TikTok API
• Data & BI: Google BigQuery, SQL, dbt Core, Looker Studio
• Consent: Cookiebot, Usercentrics, OneTrust, Google Consent Mode v2
If your numbers between Shopify/Hubspot and your ad dashboards don't match, let's connect for a quick diagnostic chat. I'll pinpoint exactly where the tracking is breaking.
