Upwork Top 1% Talent - Expert Vetted The hardest part of paid media isn't running campaigns. It's deciding what to spend on, how to measure it, and when to scale, without guessing. Most teams figure that out by burning a few months of budget. The faster path is starting with a structure that gives you real answers from week one. I work with SaaS, DTC, businesses on that structure. Sometimes that means launching a paid media program from zero — channel mix, attribution setup, conversion tracking, creative testing framework. Sometimes it means rebuilding what's already running and no longer makes sense. ▪ What I do 🔹 Paid Search (Google Ads) — new account builds, audits, restructures, RSAs with DKI logic, PMax, Dynamic Search, conversion tracking 🔹 Paid Social (Meta, TikTok) — campaign builds, creative testing frameworks, audience architecture, post-iOS attribution, MMP setup 🔹 Full-Funnel Strategy — incrementality testing, MMM-light for sub-$100k budgets, GA4 + Stripe + Shopify reconciliation 🔹 First-time setup — for brands launching paid for the first time: channel sequencing, tracking, budget pacing, creative pipeline ▪ How I approach a new engagement 🔹 Map current (or planned) spend against unit economics — what does a paying customer have to cost for the math to work 🔹 Set up or audit attribution against the source of truth (Stripe, Shopify, your CRM) — not what platforms self-report 🔹 Build campaign structure around themes, not products 🔹 Set up creative testing as a system, not a habit 🔹 Define what "working" means before turning anything on ▪ Recent results (verifiable on request) 🔹 Nishat eCommerce — 15x ROAS, $1.9M monthly sales, 70K orders 🔹 L'Oreal Virtual Beauty Festival — 35x sales vs daily avg, 9M reach 🔹 UPaisa fintech — 20% Low CPI, 100K+ app Signups 🔹 Wisesheets SaaS — full Google Ads restructure: 5 themed ad groups, 🔹 Dr. Numb DTC — 3x ROAS at ~$50K monthly sales ▪ Brands delivered for at GroupM & Publicis L'Oreal · Nestlé · Reckitt · BYD · Huawei · Red Bull · JazzCash · Etisalat (Veon) · Realme · MCB Bank · Nishat Linen · Servis Tyres ▪ Engagement model 90-day sprints, three phases: set up or diagnose, build or restructure, scale. Weekly reviews. No retainer without defined scope. ▪ What I don't do 🔹 Promise ROAS numbers I can't underwrite with data 🔹 Recommend channels that don't fit your unit economics 🔹 Bill for discovery calls or strategy decks that don't ship work Send the account access — or the brief, if you're starting from zero — and a one-line note on what you're trying to scale. I'll come back with a 30-minute teardown. No upsell, no template. With over a decade of navigating multinational digital agencies (GroupM, Publicis), I've led million-dollar portfolios, strategized with global brands, and scaled startups from small ventures to medium enterprises. Training under industry giants like TikTok, Meta, and Google equipped me with advanced certifications, enriching my journey in shaping impactful digital strategies worldwide. Top Expertise: 🔹 Media Buying (Google Ads, Meta ads, LinkedIn Ads) 🔹 Performance Marketing for DTC (Health & Wellness, Apparel, Technology, Supplements, Sports) 🔹 Digital Advertising - Full funnel Brand Development 🔹 Data Strategy Client Portfolio: Multinational Brands 🔹L'Oreal 🔹Nestle 🔹Reckitt 🔹 BYD 🔹 Huawei 🔹 Red Bull 🔹Etisalat 🔹 Veon 🔹 Real Me Mobiles Proven Experience: 🔹 SAAS 🔹 E-commerce 🔹 Fintech 🔹 Electronics 🔹 Beauty & Fashion 🔹 Non-Profit 🔹 Real Estate 🔹 Education Why Me: 🔹 Outcome-Driven Approach 🔹 Business Mindset & Strategic Thinking 🔹 Team Leader & Team Player Hands-On Experience: 🔹Media Planning & Media Buying 🔹Programmatic Media Buying 🔹Search Ads (Google & Bing) 🔹Social Media (TikTok, Meta, Snapchat, Pinterest .) 🔹Analytical Tools (Adobe, GA4, etc.) Let's not waste your ad budgets!
