Online Freelance Marketplace
  • Developed a number of systems and contributed to the team environment for numerous companies with a 100% job success rate.
  • Worked primarily as an individual freelancer and sometimes led a team of engineers remotely and once on-site.
  • Built applications, deployed them to production, and managed CI/CD pipelines. Made sure to follow best security practices to keep the systems secured.
  • Used AWS, Linode, Vultr, DigitalOcean, Cloudflare, and many other services to design and manage infrastructure. Kept the system's response time as low as possible. Used Terraform from time to time.
  • Created a custom language parser using the custom grammar defined by the client to generate queries for multiple data sources.
  • Built a fast and reliable scraper that can bypass conventional restrictions, including Google reCAPTCHA. It can also follow a predefined set of instructions to mimic human interaction, like recorded browser macros.
  • Developed resilient, high-performing, scalable microservices to distribute workload across multiple servers. Used Kubernetes a few times to manage the services.
  • Built an SDK for microservices to be leveraged by developers to quickly get started with them and face fewer surprises. This SDK left little to no room for developer mistakes while integrating these services into other systems.
  • Developed and deployed many variations of URL-shortening services with unique feature sets and complex calculations.
  • Converted large Excel files programmed to do specific tasks into functional web and desktop applications with a UI and database to retain and reuse data easily and much faster.

Pusher Compatible WebSocket Server

https://github.com/thrivedesk/rofrof
This WebSocket server is written in C++ as a drop-in replacement for Pusher. It is single-threaded, but it can handle a good amount of concurrent users. It supports Pusher protocols so that any Pusher library can also be used with it.

Country List for JavaScript and Node.js

https://github.com/i-rocky/country-list-js
This country list library is written in JavaScript to be used in JavaScript and Node.js projects. It has a name, continent, capital, currency, phone number prefix, ISO 2, and ISO 3 for all the countries in the world. All the properties can be used to search for country information.

Laravel Twilio

https://github.com/i-rocky/laravel-twilio
This is a Twilio API integration for Laravel that can be used to make and receive calls, send and receive SMS, MMS, and fax messages. The project was created when there was no good library for Twilio integration with Laravel. It also provides some help with the front end.

Eloquent Dynamic Relation

https://github.com/i-rocky/eloquent-dynamic-relation
I wrote this package to add a dynamic relation to eloquent models. There was no easy way to add a relation to existing models programmatically unless it was hardcoded. Currently, Laravel has this feature built-in.

ThriveDesk – Customer Support Solution

This is a SaaS platform for customer support based on Angular, React, and Laravel. As the architect and senior engineer, I led a team of engineers to build this platform from scratch. The team members mostly worked on the microservices under my supervision, and I worked on the core system and server infrastructure.

Log File Watcher

Wrote a file watcher using Go that watches for file changes and sends the changed data to the server to analyze. It has self-healing and error-handling capabilities that can bring it back up in case of failure. It tracks the progress and also handles log rotation and large files carefully so it doesn't take up too much server resource.

Discord Assistant Bot

A personal assistant bot written in Go that can perform certain tasks if asked through a command in a discord server. It can accept commands from the discord server, run an external program or series of programs defined by the user/administrator, and send the result back to discord.

Image Server

A CDN-like program written in Go that serves static images from a given directory and handles image type conversion on the fly depending on the request. It can convert any image to progressive JPEG and WebP of different sizes and compression ratios. It uses caching to reduce computation.

Web Crawler

A spider/crawler program written in Go using Chromium CDP (used a package for this) that can crawl through websites and gather the contents, which then can be used to extract important information. It can bypass security checks and even detect and bypass Google reCAPTCHA. It can submit forms, visit URLs, and be run automatically by using a series of commands from a JSON file.
