Hypersequent

QA Sphere, a multi-tenant SaaS test management platform. Go, Svelte 5, TypeScript, PostgreSQL.

• › One of the first engineers on the product, from early development through to a live multi-tenant SaaS with paying customers.
• › Shipped features across the whole product, from PostgreSQL queries to Svelte components: test planning, CSV import and export, Jira and Linear integrations, and most of the public REST API.
• › Reviewed 1,352 pull requests for six teammates, 2.1x my own output, and became the default reviewer on the product monorepo. Authored 648 PRs, 91% merged.
• › Built the security controls behind customer workspaces: two-factor auth and later its org-wide enforcement, SSO, RBAC across every resource type, and per-key API permissions.
• › Owned the team’s own testing infrastructure: rewrote the Playwright E2E suite, built an API benchmarking harness wired into CI, and replaced handwritten test doubles with gomock.
• › Built AI-powered test case generation with bulk creation, per-tenant quotas and rate limits, and custom workspace AI rules.
• › Owned billing and subscriptions: the FastSpring integration, trials, plan changes, seat limits, and the panel support staff run it from.
• › Cut tenant sign-up latency and eliminated provisioning failures under load by introducing a pre-created database-schema pool and making tenant creation idempotent and retry-safe.

WebNTech

• › Led frontend for an event management system that carried 30,000+ active users through the F1 Abu Dhabi Grand Prix. Also built the frontends for Misk Global Forum and the World Government Summit.
• › Reviewed the team’s code, paired with them on hard problems, and coached the junior developers.

WebNTech

• › Built React PWAs that worked offline and delivered VAPID web push notifications. Shipped a Point of Sale and Kitchen Display System for ordering food from terminals inside event venues.
• › Cut time-to-interactive on a Next.js site from 10s+ to 3–5s.

Advance Telematics Solutions

• › Built the company’s car rental management application and owned every stage of it, from requirements through deployment.
• › Wrote a GPS geofencing algorithm that alerts when a rental vehicle strays off route, the main safeguard against cars being driven off and never returned.
