Web products and backend systems I have built.
These examples show the kinds of product, backend and website problems I work on: architecture, APIs, data flows, interfaces, integrations and production delivery.
BuiltPeek
Website intelligence platform designed to scan sites, detect technologies and turn evidence into useful reports and workflows.
Turn website signals into structured technology detection while keeping the product usable for individual scans, batch workflows and operational teams.
Go/Gin backend architecture, PostgreSQL and Redis, rules-based detection, version evidence, authentication, roles and permissions, asynchronous reporting, staff/admin workflows and Docker-based deployment planning.
Clear module boundaries, auditable access control, scalable scan workflows and a product structure that can evolve without coupling every feature to the scanner.
MediaPeek
Browser media workflow and companion web experience focused on detection, quality selection and account-based product flows.
Present multiple detected media candidates clearly while keeping quality selection, batch actions and account limitations understandable to the user.
Browser extension UX, media candidate deduplication, quality selection and batch workflow design, plus a web account and pricing experience with authentication and premium-oriented product states.
Reliable state transitions, clear controls, responsive frontend behavior and a separation between browser-side media handling and account-side website functionality.
jukov.tech
A custom freelance service website built to turn direct outreach and organic search traffic into qualified project inquiries.
Create a lightweight service site with a clear offer, pricing context and a low-friction inquiry path without relying on a hosted page builder.
Responsive HTML/CSS/JavaScript frontend, PHP contact endpoint with SMTP delivery, form validation and rate limiting, privacy-first GA4 consent, Search Console setup, sitemap, canonical URLs and structured data.
Fast iteration, straightforward hosting, technical SEO foundations and measurable form conversions without sending contact-form personal data to analytics.
I can adapt the same engineering approach to your product.
Send the current situation, desired result and any constraints. I can help with the website, backend, API or a focused MVP.
