Topacharova

I ship full-stack web apps and AI automations end to end — backed by 7+ years in QA automation and DevOps engineering.

On the QA side, I built end-to-end and API test automation for a cross-border payment-orchestration platform — TypeScript with Playwright, Cucumber and Gherkin — tuned regression and performance suites, and debugged long-running distributed workflows to cut release-blocker resolution time. Earlier, as a DevOps engineer at SAP, I defined and led the team’s QA and release procedures and owned SAST security reporting.

Full-stack MVP

Nargile Orders

QR order-to-table platform for a hookah lounge

ProblemGuests wait to flag a waiter; staff re-type every order into the till by hand.

BuiltA bilingual (BG / EN) customer menu with a custom “build-your-mix” flavour builder, live order tracking, and a staff dashboard — products & availability, a visual table/QR planner, a live orders board with a server-enforced status workflow, and history. All on a contract-first OpenAPI backend.

My roleDesigned and built end to end — frontend, API, database schema and Dockerized deployment.

Social Media Report Platform

Automated client reporting for a social-media agency

ProblemEvery client report was hand-assembled in Canva each month — hours of repetitive work per report.

BuiltPulls raw Instagram / Facebook / TikTok / YouTube metrics and generates branded, client-ready reports — audience demographics, growth charts and top-performing posts — with shareable, PIN-gated client links and one-click PDF / PPTX export.

My roleBuilt the data collection, the report engine, and the client-facing delivery layer.

Camp Explorer

Bilingual marketing site for an adventure-education brand

ProblemA new Saudi youth-adventure brand — led by the first Saudi to ski to the North Pole — needed a fast, credible, fully bilingual web presence.

BuiltA responsive marketing site with English / Arabic localization (including RTL), an experiences overview with detail pages, a curriculum-aligned schools section, and full SEO scaffolding — sitemap, Open Graph and JSON-LD structured data.

My roleBuilt the site end to end on the latest Next.js, including the i18n architecture.

InstaPay

In progress

Order-and-pay-at-the-table SaaS (Bulgaria)

A product initiative: guests scan a QR, order and pay from their phone, and the order flows straight into the venue’s till — no re-typing, no hardware. I built the positioning and landing page and validated the Bulgarian legal / fiscal path (НАП, СУПТО).

Fitness Tracker

Prototype + design

Voice-first, calendar-native nutrition tracker

For people who quit MyFitnessPal: log meals by voice and write a daily macro summary to your own calendar instead of another siloed app. On-device fuzzy matching keeps it AI-cost-free. Interactive prototype plus full product and pricing design.

Side Quest

Mobile app

A playful mobile app of small real-world quests

Hands you small, slightly absurd daily missions, then keeps each completed one as a photo in a scrapbook. Card-deck interface with a local-first SQLite store deliberately shaped to become a cloud sync layer later — not a rewrite.

Quality Engineering

QA & test automation

Before building products full-time, I spent 7+ years in engineering and software quality — most recently building test automation for cross-border payments at Cellpoint Digital, and earlier defining and leading the team’s QA and release procedures as a DevOps engineer at SAP.
