Solidity Smart contract Developer

Hi, I have more than 20+ years of experience in Software Development starting my initial career in C++, COM and then ventured in .net technologies being part of large investment banks in Tokyo. As part of transition into free lancing, started working in JavaScript based technologies with React on front end and NodeJs as back-end. Over time, transfer to NestJs over Nodejs for better architecture. Currently, working as lead for development for a startup based in UK with about 10 people working on the project. Has ventured into Blockchain for initial integration, but was latter shelved for regulatory reason. During this time, I have some exposure to Solidity, Truffle and Web3 to integration and showing on the front end. I furthered this by spending sometime learning hardhat framework for professional development. I am currently based in India and I spend my spare time look at Ethereum Blockchain and understanding how this is to be leveraged in Metaverse. I want to primarily work on Solidity to develop smart contracts and oracle integrations. I'm currently looking for a PART TIME or a role where I can help some projects with my experience while gaining knowledge in Solidity to a more professional level.

I translate ideas into solid products, I also happen to write clean and maintainable code.

Hey! I'm a full stack dev with with roots in backend and cloud engineering. I have been working with software professionally since 2016. After I left Handelsbanken and the finance sector (https://www.handelsbanken.se/en/personal/digital-services/mobile-banking) in 2020, I joined IKEA to bring their IoT gateway to life. When we launched the DIRIGERA IoT hub at IKEA (https://www.theverge.com/23420136/ikeas-dirigera-smart-home-review-price-specs) in late 2022 I subsequently joined an automotive company called RemotiveLabs (https://RemotiveLabs.com) that is trying to disrupt software in the automotive industry. Parallel to my full time job I always strive to be creative and utilize my free time to the fullest. Since 2018 I have been building mobile games with Crankoid Games Studios (https://crankoid.com) and in more recent years also blockchain tech. My first blockchain project was a custom off-chain/on-chain NFT contract with an accompanying backend and frontend (https://pawsters.io) that is capable to scale massively in the cloud. I consider myself an expert in Java, Kotlin, C#, Typescript/JavaScript/Nodejs/Reactjs and I can handle my own in Go, Python and Solidity. In the backend domain I am entirely convinced in building infrastructure as code and going the cloud first route. When it comes to frontend I always build solutions for both mobile and desktop users, the visual experience and intuitiveness is extremely important and cannot be overlooked. I thrive when I get to turn ideas in to sustainable products, solve problems and write clean code. My approach is often to try to solve the real problem before jumping the gun. I iterate forward, I do not believe in big-bang releases and do my best to smoke out scope creep. And lastly, user feedback trumps opinions. I'm currently looking for a part time role (~10 hrs/week) as I am fully committed to my current role at RemotiveLabs. If my profile sounds interesting, don’t hesitate to reach out! If the timing is off we can at least keep each other in our respective network /Ola

Curious developer with a math background

I'm a curious and highly independent developer with a massive background in applied math and machine learning. I am coding for more than 8 years, starting with IOS jailbreaks and games reverse engineering. I'm developing backend for 5 years and managing software development teams for 3 years. I have successfully delivered more than 15 projects as a team lead and tonnes of projects as a backend developer. I have been developing scalable data mining tools, social networks botnets, low-latency APIs, machine learning integrations and more! My biggest project was online gaming web site (100k+ MAU) for multimillion telecom company. I was heart of both operations and backend development. I have created the roadmap and hired several teams. Since the project was urgent I've designed and implemented the whole backend and protected it from several hackers attacks My craziest project was Instagram data mining botnet based on 1k+ accounts, mining 1M+ social interactions per day. On a top of data mining tool I’ve developed behavioral research module, which was utilizing the data and optimizing mining patterns. My funniest project was Tinder style service for searching flats, with interiors style recommendation system based on sophisticated linear algebra approach (Gram Matrices + PCA) applied to VGG neural network intermediate tensors. I've combined it with Approximate Near Neighbors solution by Spotify and made Telegram bot as the interface. My most valuable experience was teaching others how to code and writing tonnes of educational and inspirational articles about IT.
