AdTech systems I've worked on, debugged and optimized.

Programmatic buyers and SSPs silently drop bid requests due to subtle JSON schema violations (such as missing poddur in CTV pods, invalid ext.eids, or unencoded GDPR user.ext.consent strings), contributing to lost bid opportunities and unfilled inventory.

SSPs, DSPs, Programmatic Publishers, and Integration Engineers.

Built an interactive, in-browser validation engine that evaluates real-time bid requests and responses against IAB specifications. Features 1-click test payloads (Display Banner, CTV Pod, Cookieless EIDs, Invalid Payload) and an instant clipboard export tool formatted for Jira and Slack tickets.

Identifies missing podding objects (podid, podseq), low tmax timeout thresholds (<50ms), malformed user consent strings, and invalid devicetype values.

Ad server delivery conflicts and revenue loss frequently stem from misunderstandings of line item priority hierarchy (Sponsorship 4 vs Standard 8 vs Price Priority 12 vs Open Bidding) and dynamic price floor competition.

Ad Operations Teams, Yield Managers, Ad Server Solutions Engineers, and Publisher Monetization Leads.

Built an interactive ad server simulation workbench allowing engineers to test priority overrides, simulate external header bidding CPM inputs, and inspect step-by-step waterfall decision paths in real time.

Demonstrates why a $6.00 Price Priority line item loses to an eligible $0.00 Sponsorship line item due to guaranteed reservations, and isolates floor price blockages.

Server-Side Ad Insertion frequently introduces playback buffering, audio loudness jumps, aspect ratio stretching, and broken quartile tracking beacons across Connected TV devices.

Connected TV (CTV) Publishers, SSAI Solution Architects, Video Engineering Teams, and OTT Streaming Platforms.

Constructed an interactive stream inspector that demonstrates synchronized video playback with ad segment timing graphs, SCTE-35 cue markers, and tracking beacon firing logs.

Verifies discontinuity tag placement, manifest timing accuracy, and client vs server beacon firing parity.

AdTech onboarding and client technical escalations require structured, reproducible root-cause analysis across tracking discrepancies, API timeouts, and protocol errors.

Solution Engineers, Technical Account Managers (TAMs), and Level 2/3 AdTech Support Engineers.

Curated a comprehensive 100-question technical diagnostic repository with 10 deep incident case studies and 5 practical mock integration blueprints covering real-world AdTech problem solving.

Provides step-by-step playbooks for resolving VAST 303/405 error cascades, Prebid timeout tuning, and Sellers.json / SupplyChain verification.

Modern AdTech operations require bridging disparate ad server logs, SSP bidstreams, and buyer reporting APIs to detect impression discrepancies and pacing anomalies before billing reconciliation SLA breaches occur.

Technical Specialists, Solutions Architects, and Partner Integration Engineers.

Constructed a secure, read-only REST API endpoint layer paired with a standalone Python client and an advanced SQL query library (CTEs, Window Functions) that calculates real-time CTR, eCPM, and multi-partner billing variances.

Isolates render abort drop-offs, VAST 405 codec error surges by player device, and automated underperforming campaign alerts (CTR < 0.5%).
