## ABOUT

Senior software engineer with 9+ years of experience building and leading frontend-heavy products — from ML annotation tooling and KYC/identity platforms to high-stakes crypto trading interfaces handling real user funds. Comfortable well below the UI surface: WebAssembly with C++ bindings, canvas rendering, WebRTC, and blockchain transaction flows. Track record of leading teams, mentoring developers to promotion, and shipping measurable improvements in performance, reliability, and delivery speed.

## EXPERIENCE

Senior Software Engineer

Solflare · Aug 2025 — Jun 2026

Integrated the prediction markets frontend on Solflare's trading team — two engineers, ~1 month, shipped on schedule for a competitive public launch across web and extension
Redesigned core trading flows — token swaps and sends, plus gasless swaps and private sends — reworking the transaction signing flow and instrumenting it with feature flags, analytics events, and A/B tests
Built the frontend for Explore, an in-wallet discovery hub for Solana dApps, trending tokens, rewards, and ecosystem news, across web and extension

Senior Software Engineer

Microblink · May 2022 — May 2025

Led a team of 3 through a 4-month rewrite of the annotation editor from SVG to a canvas-based renderer (PixiJS), shipped on schedule — the new editor handled 1,000+ annotation objects where the old one struggled past 50
Unified four product UIs from separate repos sharing code via Git submodules into a single NX monorepo, and built a drag-and-drop workflow builder (React Flow) for configuring annotation flows
Built a framework-agnostic device-to-device handoff library (SolidJS, WebRTC): moves document scanning from desktop webcams to the user's phone camera and returns results to the browser — embeds into any host framework with no runtime
Owned Microblink's public demo site (Next.js), including a new design language across all product demos and usage gating via browser fingerprinting with Redis-backed counters
Shipped features on the document scanning Web SDK, running in-house AI models in-browser via WebAssembly — wrote the C++ WASM bindings serving as the interface between JavaScript and the WASM runtime
Lead frontend developer (team of 2) on a KYC identity verification platform built from scratch — set up the Turborepo monorepo and built the Web SDK executing customer-defined verification steps (React, XState, React Aria)
Integrated ID R&D face-match with a custom UI layer — an oval face guide with live progress feedback to improve completion

Frontent Tech Lead

Deegloo · Sept 2021 — May 2022

Lead developer on a greenfield configuration-first React framework for rapid UI development, designed with Java backend developers so non-UI engineers could build frontends themselves; distributed as a private npm package via a GitLab CI/CD pipeline I set up
Led a team of four frontend developers — sprint planning, onboarding, mentoring, and technical interviews for new hires

Software Engineer

Superbet · Sept 2020 — July 2021

Owned the app Superbet's traders used to structure sports hierarchies and localized naming across three national markets, driving the main site's betting offer
Rebuilt CI for a shared component library, halving build times and speeding up package releases for consuming teams
Built a Node.js + RxJS WebSocket proxy replacing an event firehose with per-subscription streaming — trader tabs went from crashing every ~2 hours to lasting a full workday

Software Engineer

Endava · Jul 2018 — Sept 2020

Core-team member on Erecruit, a 10+ year-old enterprise staffing platform (.NET, 30+ devs) — worked across localization, the workflow engine, integrations, search, and CI/CD, and on the new React frontend

ASP.NET · MSSQL · PowerShell · React · TypeScript · Emotion · Lerna · Jest

Software Engineer

Syskit · Aug 2016 — Jul 2018

Owned the shared React component library consumed by multiple company products

React · TypeScript · SASS · Electron
