# Alexei Diaz > Software Engineer — AI Product & Frontend Architecture | Building the shared infrastructure that lets AI teams ship faster Location: San Jose, California, United States Profile: https://flows.cv/alexeidiaz Software engineer specializing in AI-native product development, with 15+ years building at scale — from Google's $90B+ Ads platform to Netflix's Globalization tools to AI agent systems at Oscilar. My background is in mathematics (dual MSc), which shows up in how I work: I care about the foundations that let teams build faster, not just the feature in front of me. At Google, code I designed stayed in production for seven years. At Oscilar, the GenAI framework I built is now used across three product lines without rework. Current focus: full-stack AI engineering — shipping AI agent features end-to-end across backend, API, AI layer, and frontend. The problems I gravitate toward sit at the intersection of technical depth and real stakes: enterprise customers, compliance use cases, P0 deadlines. ## Work Experience ### Software Engineer @ Oscilar Inc Jan 2024 – Present | Palo Alto, CA - Built the GenAI chat framework now used across three product lines — GenAI DAG Generation, GenAI Analytics, and GlobalAI — reducing per-feature AI integration to near-zero rework; early beta customers reported 80% faster workflow building. - Shipped Rule Recommendations Agent (for workflow optimization) frontend end-to-end from scratch — recommendations panel, performance analytics, filtering, and feedback loop; recognized at launch as a "frequently requested feature and huge milestone." - Delivered full workflow testing system supporting a 35K-record fintech deployment as a key contribution to a company-wide P0 initiative. - Owned the expression system underpinning every workflow feature; extended and maintained it across 5+ downstream products without regression. - Transitioned to full-stack AI engineering on the Fast AI Agents team, taking ownership of features end-to-end across API, AI backend, and frontend. ### Senior UI Engineer @ Netflix Jan 2021 – Jan 2023 | Los Gatos, California, United States Member of the Globalization team, building tools for dubbing and subtitles, on the Logistics Management track: - Championed Code Health initiatives, integrating tools that elevated code quality by 20% and reduced maintenance costs by 15%. - Addressed the most challenging system bugs, significantly reducing user-perceived latency in both the UI and backend, restoring user trust by 70%. - Spearheaded the implementation of essential backend features for various projects, ensuring the successful completion and launch. - Emphasized user-centricity by prioritizing improvements based on feature usage data, leading to a 25% increase in user satisfaction. ### Software Engineer @ Google Jan 2014 – Jan 2021 | Mountain View, CA - Played a key role in building the Opportunities track of the Ads Sales Force CRM, overseeing a substantial revenue of 90+ billion dollars with a codebase exceeding 500k lines of code. - Spearheaded the domain layer revamp, leading to faster development (20% reduction in coding time), improved testing efficiency (30% decrease in test execution time), and enhanced code quality (15% fewer bugs), contributing to a $1 billion+ revenue increase. - Acted as a Code Health champion across teams and mentored an intern to enhance static analysis tooling, while also advocating for latency reduction measures - The code I developed remains in production after 7 years, highlighting its robustness and quality. - Successfully facilitated the rapid launch of AutoML Vision for Object Detection amidst a PR crisis, showcasing adaptability and resilience under pressure.
