Wondering if it's possible to have a bug-free, scalable solution? I've seen and solved it all. With a commitment to deliver and a track record of success, I am here to protect your project from common setbacks and elevate it to its highest potential. Hi! I'm a Senior Full-stack developer with over a decade of experience in the tech industry. I specialize in delivering comprehensive frontend and backend solutions, from concept to deployment, bolstered by solid experience as a Solution Architect and a Dev Lead. In 2015, I gathered my own web dev team from the ground up, as an extension of my software developer expertise and wisdom. Now, with over70 successful projects behind us, we focus on creating IT solutions for businesses to guarantee their growth and prosperity. ---=== Why I Stand Out: ===--- - Unmatched Reliability: Every project I undertake is guaranteed to reach completion, irrespective of the initial condition or challenges encountered along the way. - Continuous Support: My relationship with clients extends beyond project completion.

This flexibility allows me to tackle projects of any size and complexity, delivering high-quality solutions on time and within budget. - End-to-End Solutions: From initial consultation to final delivery, I manage all phases of the development cycle. ---=== My Technical Foundation: ===--- - Frontend Expertise: Proficient in HTML, CSS, JavaScript, TypeScript, and an array of frameworks & libraries including React.js (with Redux, Thunk, Sagas, Next.js), Bootstrap, Material UI, CSS in JS, Tailwind, and React-Admin. - Backend Proficiency: Skilled in Node.js, Express.js; along with Feathers.js, RESTful API, GraphQL development, Socket.IO, Strapi, and BullMQ. - Data Visualization Mastery: Experienced with D3.js, Chart.js, GSAP, Three.js, React Three Fiber, and techniques involving Canvas and SVG. - Database Management: Competent in managing data using SQL, PostgreSQL, MongoDB, and ElasticSearch. -DevOps & Deployment: Knowledgeable in Docker, Kubernetes, and implementing CI/CD pipelines with GitHub, GitLab. kurang

Above that, I also have a postgraduate degree in Data Science. I have very rich experience with database administration and database programming. For more than 7 years I have been working as a SQL Developer / Database Administration for various companies. The most experience I have is with a PostgreSQL database. I worked as a PostgreSQL Database Administrator /SQL Developer for about 6 years in the company which provides iGaming industry solutions. I was responsible of more than 100 PostgreSQL clusters. Including production, test and RC environments. Most databases were several hundred GB and the largest reached 1.5TB. My daily duties included: - Installation and configuration of new PostgreSQL clusters. - Creation of database replication - streaming and logical. - Routinely checking that all databases are working properly. Including the fallowing: keeping an eye on monitoring (Zabbix plus our internal solution), responding to alerts, maitanace of monitoring (adding new things to monitoring and improving current ones), routinely checking of databases logs, catching and optimizing slow queries. - Maintenance of existing PostgreSQL clusters. Including the fallowing: changing the databases' configurations, creating new databases' replications. - Maintenance of existing PostgreSQL databases. Including the fallowing: maintenance of database indexes, tables, views, functions, procedures and triggers. - Creation of new databases objects such as: tables, views, procedures, functions, indexes and triggers. - Creating new and maintenance existing reports. Above that, I have a lot of experience as a SQL Developer with BigQuery and Snowflake databases. I also know Databricks and DBT - I was creating repots for the USA iGaming market regulators using these tools. My strengths are analytical thinking, good work organisation, focus on solving problems, and personal development. Professionally I am interested in Big Data and Data Science, so I think that will be the direction of my development. My hobby is astronomy, ancient history and travel. I hope you liked my profile, please do not hesitate to contact me. Best regards. kurang

IMPORTANT INFO !!** Paul L. @paul612 who left last comment is a scammer. He wanted me to test his .apks but he couldn't even build them properly and they didn't boot up at all! And then he wanted me to develop for him for free. Don't be like @paul612, be honest and I will be honest **** I have done a lot of projects connected with virtual reality, Oculus Rift, Oculus Quest / GO and HTC Vive (I developed unique calibrating system for making free roaming VR Arena). Also I have a some knowledge about design, drawing, 3D modeling, and sound engineering because for some years I have been making games utterly alone. I am not afraid of any kind of challenge. === If you do not speak English we can try to communicate via translators I am sure that we will manage to do it :) kurang
