# Selected work — Alexander Mescheryakov

I focus on engineering outcomes and processes that drive business, not just follow it: speeding up time–to–market, flexibility, proactive quality, stability and performance improvements, getting rid of manual routine work.

## Littledata — Senior Software Engineer (Feb 2025 – Present)

At Littledata, a Shopify data-layer service for analytics and multi-channel advertising, I rebuilt a legacy application with React, TypeScript, and Node.js, including Remix, NestJS, Next.js, and MongoDB. I deliver features end to end with product, design, and QA. I reduced client-facing production issues to **zero**, shortened the design, engineering, and QA cycle by approximately **50%**, and improved delivery by approximately **30%** through Storybook and Chromatic. I also introduced shared AI-assisted workflows, strengthened observability and E2E coverage, and implemented GitHub Actions CI/CD for bare-metal deployments.

## Vectary — Lead / Senior Software Engineer (Mar 2021 – Feb 2025)

At Vectary, a 3D/CAD/AR collaboration platform, I led React and TypeScript delivery. I improved application loading by **10×** and monorepo builds by **20×** while reducing CI costs by approximately **30%**. I managed a monorepo of approximately 45 packages, migrated tooling to GitHub Actions, improved design and engineering collaboration through a Storybook and Chromatic component system, and optimized the API gateway and 3D viewers built with Vite, WebGL, and Three.js.

## Earlier product engineering (0→1 / startups)

In earlier roles, I built and modernized product experiences end to end, which developed my UX and product judgment as an engineer. At Fohlio (US), onboarding conversion increased **3×** after I joined. At IQ300, UI and front-end modernization contributed to **450%** active-user growth and a **120%** increase in signups. I also delivered design-system and front-end collaboration work in Germany, plus product engineering for 3dEYE (Canada), US healthcare/insurance, and UK healthcare/wellness/performance.
