Varun Sharma

I’m a Senior Backend & Applied AI Engineer with 4 years building AI and ad-tech systems in production. I specialize in architecting high-throughput event-driven systems and LLM-powered automation that ship reliably into real usage.

As a Senior Developer / Team Lead, I architected a production-grade AI campaign automation platform processing 15K+ async jobs/day, improved campaign CTR by 23% and reduced CPC by 12% using Gemini-powered automated bidding logic. I also built production time-series revenue forecasting pipelines on 500K+ records, achieving 89% accuracy, and cut analytics reporting latency from hours to minutes by designing scalable, concurrent ETL pipelines across marketing data sources.

I’ve fine-tuned and productionized a PyTorch lip-sync model and engineered an OpenCV and vision-language OCR pipeline that reduced manual processing time by 96% (2 hours to 5 minutes). I mentor engineers through structured code reviews and technical planning, focused on dependable architecture and measurable outcomes.
