VONQ — HAPI Elements & EQO

Turned multi-year partner integrations into weeks of work.

I architected HAPI Elements — a platform that lets hiring software vendors plug VONQ's job-campaign workflows directly into their own products, instead of rebuilding the integration from scratch. I also led the broader frontend re-architecture that now powers both HAPI Elements and EQO, VONQ's AI-driven recruiter platform.

• Architected HAPI Elements, VONQ's production SDK and embeddable-widget platform that lets Applicant Tracking Systems integrate VONQ's Hiring API (campaigns, contracts, products, baskets, wallets, checkout, order journeys) as drop-in widgets — a Next.js / TypeScript / Tailwind monorepo with a MobX-backed SDK on window.hapi, an iframe-based widget UI layer, a public @vonq/hapi-elements-types npm package consumed by integrators, a Fumadocs developer portal (marketing + integration guides + versioned changelogs + OpenAPI reference), and multi-environment Docker / AWS ECS deployments. Compressed partner integration timelines from years to weeks.
• Defined and owned the public SDK surface with documented backwards-compatibility contracts (SDK functions, getters, setters, events, window.hapi / window.hapiInjector globals, HTML / ARIA / data-* hooks, translation keys, state shapes, types package) and a typed deprecation cycle, so ATS integrations survive feature work without breakage.
• Drove the end-to-end re-architecture of VONQ's frontend into a shared module system — domain services, state, events, validation, i18n (6 locales), and TypeScript types — reused by both HAPI Elements and EQO, eliminating duplication, raising quality, and turning new product surfaces into composition exercises rather than rewrites.
• Spearheaded EQO end-to-end (the AI-driven recruiter platform formerly known as KoPilot): job authoring, candidate flow, and ATS surfaces — reusing HAPI Elements' shared packages and adding AI agents that automate application and applicant-evaluation workflows.
• Owned partner onboarding as the technical point of contact, turning integration support from a recurring engineering tax into a documented, self-serve flow backed by the developer portal, regression tests guarding the public SDK surface, and a Playwright E2E suite for both Hiring Elements (browser UI) and the Hiring API (request mode).

FriendFinder Networks — Members & Models Interfaces

Replaced decades of duplicated frontend code with one reusable system.

I led the frontend architecture for FriendFinder Networks' flagship dating properties — building a single component library now powering hundreds of affiliate and co-branded sites, and leading a multi-team senior engineering organization across time zones and product streams to unify how members and models experience the platform.

• Architected the FFN Frontend Library (React + TypeScript + Tailwind with tailwindcss-classnames, MobX, CSS Variables-driven theming), now powering the company's flagship adult-dating properties — a single component substrate for hundreds of affiliate/co-brand sites.
• Led a multi-team senior frontend engineering organization across multiple time zones and the company's flagship product streams; established cross-department communication rituals with leads and managers to align short- and long-term roadmaps.
• Engineered reusable React modules — Messaging, ThemeManager, APIFacade, AxiosBridge, LayoutManager, Media Viewer/Manager — shipped into multiple production apps.
• Engineered a mobile + desktop live-streaming player at parity with Twitch and YouTube but optimized for mobile browsers — adaptive design with full portrait/landscape layouts, multi-zone tap and gesture interaction (tap, double-tap, swipe, pinch), layered z-index choreography across overlays / controls / chat / reactions, animated transitions, and runtime browser + version detection so quirks of older mobile WebViews degraded gracefully instead of breaking the live experience.
• Rewrote the broadcasting module from AngularJS into a customizable React module integrating WebRTC, WebSockets, Wowza, and Nanoplayer, unblocking reuse across products and removing a legacy maintenance liability — paired with the streaming player above to deliver a full live experience across desktop and mobile browsers.
• Architected a Storybook system tested with Jest / Enzyme so engineers could discover, copy, and ship components without breaking dependent apps; institutionalized code-review and peer-coding rituals.
• Drove the JS → TS migration, eliminated Bootstrap, Material UI, and redundant third-party packages in favor of the in-house library, measurably reducing bundle size and onboarding time.
• Planned and started migration of decades-old Perl codebases (the company's flagship adult-dating properties) to React / TypeScript on the shared library.

eTaşın — booking & logistics platform

Built the booking system that runs a fast-growing moving & storage company.

Customers can schedule moves with full origin, destination, and inventory details, or reserve storage by duration and location — directly from the public website.

VQ Labs — HonestCash

Shipped an open-source publishing platform where writers earn crypto from readers.

I architected and built HonestCash end-to-end — a Medium-style platform where authors get paid in Bitcoin Cash through reader upvotes. Full ownership of backend, frontend, and crypto integration, with adjacent Ethereum smart-contract prototyping.

• Architected and shipped HonestCash, an open-source Medium-style publishing platform where authors earn Bitcoin Cash via reader upvotes; designed and implemented both backend (Node.js, MySQL) and frontend (Angular 8 Universal, NgRx Store & Effects, Karma), with adjacent Ethereum smart-contract prototyping using Solidity, Truffle, Ganache, and web3.js.
• Open-sourced the platform at honest-cash/honestcash, giving the codebase a public audit surface and continued discoverability after the company wound down.

UBI Automation — corporate site & admin dashboard

Delivered a multilingual corporate site and internal dashboard for a manufacturing client.

Extracted the client's requirements, then designed and built a multilingual public website plus an internal dashboard the company uses to manage their project showcases. Live at ubiotomasyon.com.

TDSmaker — drag-and-drop datasheet platform

Turned a drag-and-drop datasheet app into a complete paid SaaS product.

Rewrote TDSmaker's datasheet builder into a more reliable, richer drag-and-drop experience. Added user management, billing, customer-support tooling, and ten platform integrations so the product could grow as a paid SaaS — along with the marketing site and a mobile companion app.

• Rewrote the drag-and-drop datasheet builder from jQuery to AngularJS, removing a class of stability bugs and unlocking a richer interaction model.
• Engineered an RBAC system enabling client admins to govern user access across CRUD operations on datasheets.
• Shipped customer-support tooling (log-in-as) and an accounting/billing dashboard, reducing support and finance friction.
• Integrated Stripe, Algolia, HubSpot, Intercom, Segment, Autopilot, Mailchimp, Swagger, Sentry, and several Google APIs into a single product surface.
• Built a custom SFTP-based multi-environment deploy script with CLI prompts and Slack notifications, including the published gulp-sftp-with-callbacks package for lifecycle callbacks around SFTP deploys — early-career DevX work that foreshadowed later platform thinking.
• Refactored Node.js backend to async/await with concurrency primitives, eliminating callback-hell stalls and improving throughput on heavy datasheet exports.
• Shipped the supporting marketing site (Express + Jade/Pug) and an Ionic mobile companion app for viewing, sharing, and exporting datasheets as PDFs.
