ScholarTrip is the student/youth OTA on the Kivork Yii2 platform I helped ship - discounted search, eligibility and reservations on the same GDS/payment core as Ovago and Hop2.
Details
Ovago is the flagship consumer OTA on a Yii2 platform I helped build: flights/hotels/group quotes, GDS, Stripe/insurance - and the same core white-labeled to 30+ brands (Hop2, ScholarTrip, Wowfare, GTT, Healthcarefares).
Details
On Hop2 I hardened checkout payments (cards + pay-later) and the traveler cabinet - on the same Kivork Yii2 engine that also powers Ovago, ScholarTrip and 30+ other OTAs.
Details
Wowfare is a private-fare OTA on the Kivork Yii2 platform I helped ship - flights, hotels, checkout and cabinet from the same core as Ovago/Hop2, not a separate stack.
Details
GuruFare runs on the same Yii2 hybrid I helped build for Kivork: search, hotels, sign-in and help - one engine, many storefronts.
Details
AranGrant is a white-label OTA on the Kivork Yii2 engine I helped ship - flights, hotels, about/help and sign-in from one multi-tenant codebase.
Details
Healthcarefares is the healthcare-worker niche OTA on the Kivork platform - same Yii2 search/checkout/GDS core, different eligibility and brand rules.
Details
GTT Global is the B2B/agency face of the Kivork stack: agent sign-in/sign-up, booking and ops on the same GDS/payment core as consumer OTAs.
Details
ChatDeal is a deals-positioned OTA on the same Kivork Yii2 hybrid - hotels, about, sign-in and checkout without a separate booking codebase.
Details
StudentMiles is another youth/student OTA on the Kivork engine alongside ScholarTrip - discounted search and booking from the same Yii2/GDS core.
Details
UnderPricer is a cheap-flight white-label on the Kivork Yii2 platform - hotels, about and checkout from one engine shared with Ovago and Hop2.
Details
AllSavingsTravel is another consumer OTA on the Kivork hybrid I helped build - flights, hotels and help/about from the multi-tenant Yii2 core.
Details
SkyMonde (hoteles y vuelos) runs on the same Kivork Yii2 booking platform - help center and storefront on the shared GDS/payment core.
Details
ShopRezzo is a Yii2 affiliate shop that refreshes products from partner sources and monetizes via referral links and recommendations - Amazon Associates, ShareASale and other programs.
Details
I built RevYou from a blank Yii2 Advanced tree: Amazon testers claim deals, verify order IDs, post reviews, get cashback via Stripe; sellers run campaigns; affiliates bring partners. Docker/nginx split frontend, backend and affiliate.
Details
I built a Yii2 Advanced investment platform: LPs see fund vs personal value on Highcharts, share % and yield; ops invest or disburse, track watches, liquidity, bank accounts and general costs. Docker/nginx splits frontend and backend.
Details
Inside a ~250-person travel company I shipped Yii2 booking/inventory features that had to survive peak search and reservation load across hotels, flights and car rentals.
Details
I extended LandexCorp product surfaces for residential and commercial real estate plus insurance modules - listings, workflows and business rules for agents and clients.
Details

Details
I built Persona.ly CRM.API: Yii2 hub that imports mobile-ad opportunities (DSP, Mob, TopMob), builds FFmpeg GIFs to S3, then exports create/update items and subitems onto Monday.com boards. Copper notifications and Pipedrive sit on the same cron mesh.
Details
I shipped SDR Deck as two repos: a React 18 / TypeScript / MobX studio (drafts, bundle search, creative carousel, react-to-print PDF) and a Yii2 JSON API that parses Play/App Store bundles, serves case studies, RT segments, geos and stores decks.
Details
I built Phantommicro as a Yii2 micro-service: a pool of PhantomJS render accounts, random rotation, ban/unban, optional residential country proxy, and an HTTP parse endpoint that returns fully rendered HTML. No public URL.

Details
Music Factory (Фабрика Музики) is a Kharkiv music school. I shipped a custom PHP/WordPress site: trial-lesson funnel, bilingual UK/RU, pricing, teachers and Telegram bots so parents book a 69 UAH trial instead of hunting a phone number.
Details
The VOU is a men's personal-styling brand: paid image packages, books, colour palettes and quizzes. I shipped the WordPress/WooCommerce stack so a quiz about body or face shape can become a Stripe checkout instead of a dead blog post.
Details
I owned Haris SMS end to end: Yii2 SaaS for bulk and scheduled SMS, phonebooks, templates, reseller billing, Stripe/PayPal/Paystack, and a gateway mesh (Twilio, Nexmo, Clickatell, Infobip, Plivo, ClickSend).
Details
I built a Yii2 forex-broker stack: client cabinet with accounts, PAMM rankings, KYC, 2FA, partner CPA, SMS gateways and a multi-locale marketing site (RU/EN/ZH). No public URL.
Details
I shipped OTF Transport as a Yii2 Advanced CMS: public marketing for East London haulage, articles/FAQ, quote capture, and a Dockerised admin so staff can edit pages without a deploy.
Details
I designed and shipped a Laravel 11 JSON transit gateway: React asks /?q=, the API hits the upstream catalog, Redis-caches the payload, then returns a strict filtered title list so the SPA search stays fast and exact.
Details
