Savanah AI — Co-Founder & CTO — New York, USA Jan 2026 – Present AI creative studio for fashion and e-commerce brands: product imagery, video, moodboards, and brand-aware content. Subscription + credit-metered SaaS.

Project: AI Image Generation Platform (AI Studio + Nano Banana Pro) Built the flagship image-generation product powering 10+ fashion use cases including try-on, multi-angle, sketch-to-reality, color change, and brand-guideline-driven generation. Architected a multi-provider routing layer across Google Gemini, ByteDance Seedream, and Grok Imagine with category-aware dispatch and runtime-switchable provider flags. Designed the multimodal prompt system and async job pipeline, delivering 1K/2K/4K outputs with subscription-gated credit metering.

Project: Video Generation Pipeline

Delivered end-to-end image-to-video generation across 4 models — Veo 3.1, Kling 3 Pro, Hailuo, and Luma Ray 2 — behind a unified frontend API.

Designed a three-route poll-based architecture for long-running provider jobs, with FFmpeg watermarking and dedup-guarded asset registration on Cloud Run. Project: Backend Infrastructure & Cloud Run Migration Migrated 3 memory-heavy services from Supabase Edge to Google Cloud Run, eliminating OOM crashes and unlocking 4K image and watermarked video output. Designed the Postgres schema and RLS model from scratch — 40 tables, 160+ migrations, and atomic credit deduct/refund RPCs.

Project: Commerce, Billing, and Public API

Shipped the commerce layer end-to-end: Stripe subscriptions, credit top-ups, and a Shopify Managed Pricing integration with an embedded admin app.

Built a public /v1/* API with per-key Bearer auth, monthly spend caps, and metered Stripe billing. Google — Full-Stack Software Engineer — New York, USA Sep 2019 – Dec 2025 Project: Differentiated Assignments

Solved significant technical challenges related to partial student group selections and data exclusivity, a critical component for the feature’s success.

Led a mobile group, defining the technical roadmap and owning the end-to-end delivery of a core instructional feature.

Architected a complex backend personalization schema in Spanner and designed the 3rd-party developer APIs.

Project: On-Call & System Reliability (Tech Lead)

Served as Tech Lead for a 9-engineer on-call rotation, improving system reliability by driving a 62% reduction in paging volume through a strategic migration to reliability-focused alerting (SLO-based). Project: Core Classroom Features (Student Groups & Grading Scales) Designed and delivered the backend for key features, including Student Groups (serving 60K+ MAU) and Grading Scales (adopted by 30,000+ teachers).

Made critical design trade-offs that saved over 12 weeks of engineering time, enabling the team to meet an aggressive launch deadline.
