I implemented the full-stack architecture for this wedding-locator service. Technologies used in development were:

Server-side: Nginx, PostgreSQL, SQLite, Python, Django, Python Imaging Library (PIL/PILLOW)

Client-side: JavaScript, jQuery, Ajax, Handlebars, HTML, CSS

I architected and implemented a full-stack web service that enables users to design, construct, and host customizable online landing pages. This included designing the system architecture, developing both the front-end and back-end components, and integrating database and user behavior tracking components.

I designed and implemented the full-stack architecture for 15 landing pages (pixel-perfect HTML+CSS was implemented by another person).

Technologies used for development were:
Server-side: Nginx, Node.js, Grunt.js, Handlebars Precompiler, PHP
Client-side: JavaScript, jQuery, Ajax, Handlebars, HTML, CSS

This project was based on parsed US government insurance plan databases. It included a flexible filtering and adaptive cost estimation algorithm (factored in age, smoking factor, annual income, family members, and automatically calculated subsidies).

A course editor that allows the creator to construct educational steps with embedded videos, illustration images, formatted texts, and formulas.

The courses' portal includes flexible course access management (grouped access lists with tagged resources linkage) and running courses, with progress tracking included as well.

The detection engine is based on minutia point detection. The web UI allows users to add new fingerprints and search the entire database by fingerprint images. Images were given as input, and preprocessing, feature extraction, and index building were performed to store and search fingerprints.

I contributed to this project by developing a suite of utilities, including automated email notifications, status tracking, and specialized tools such as a template-based insurance offer generator. These tools were designed for independent use and significantly streamlined the manual processes involved in handling insurance orders.

The tool helps web developers validate JSON code, layout it in tree-based form, and navigate through collapsing tree branches.

Also, the tool supports simple installation to the command line for Debian-based operating systems and macOS; users can use it on any local JSON script output, sending it automatically to a dynamically opened browser tab.

Online color filter tool for checking if a website is suitable for color-blind persons. URLs are filtered for multiple kinds of forbidden content, then dynamically rendered as an image with a color scheme generated according to color-blind modeling algorithms, including:

• Protanopia (red/green color blindness; anomalous red cones)
• Deuteranopia (red/green color blindness; anomalous green cones)
• Tritanopia (blue/yellow color blindness; anomalous blue cones)
• Greyscale/achromatopsia (quick check for all forms of colorblindness)

This tool optimizes the sprite loading technique that websites use. A user can drag-and-drop or select sprites from local storage and have them rendered as a single sprite container image with CSS snippets automatically generated.

This system allows users to specify custom questions to help distinguish the clients' state. More than five websites are implemented on the same core system with specific questions and logic.

The system supports flexible configuration of question lists, answer variants, answer logic, and results estimation logic, with dynamic report generation on why the system gives a certain result.

All data is dynamically analyzed and displayed as multiple layers as a specifically configured Google Maps widget. Zip-code regions are highlighted with detailed stats and hovering descriptions. Multiple tools with different analysis algorithms have been implemented.

A management tool designed for databases of at least 6 million data records (engine tested to perform well for up to 20 million records) with a dedicated storage server configured with optimal storage costs and management efficiency. An automatic conflict resolver was implemented with the flexibility to add further rules and resolve scenarios.

A web service for building online quizzes of different complexity, allowing custom question types, dynamic content loading, branching, and individual report evaluation. Quizzes could be integrated into any existing site. Dynamic integration with Google Analytics events and navigation actions is supported by the integration. Rich stats on quiz fulfillment, places of quitting, and time-to-answer are being collected and reported daily via email table to all quiz-related managers. Binding to external stats was implemented, making complete funnel analysis possible. Admins are allowed to customize and tune reporting logic, question content, influences, branching conditions, and more.

A flexible CMS supporting custom blocks layout, with SSR and rich SEO features list. Great page speed results and overall pages' rankings. Site admins have a UI to completely manage per-block content, combine blocks, copying, moving pages, and more.
