Senior Fullstack Developer (.NET)

Hello, my name is Angel Nikolov and I am an indie developer working on a project helping people all over the world find remote jobs.
 
 I recently noticed some of your advertisements on similar job boards like stackoverflow and wondered if you’d be interested into featuring an ad on remote frontend and backend focused job boards.
 
 I am working on <a href="https://remotefrontendjobs.com">https://remotefrontendjobs.com</a> and <a href="https://remotebackendjobs.com">https://remotebackendjobs.com</a> as a side-project and I am looking for more early-adopters.
 
 
 What I am aiming for right now are early adopters to help me clean up the process of posting a job and support communication so I’d love to have you on board.
 
 In fact, since both job boards are aggregating multiple different sources some of your advertisements are already listed and you can see some of them here - <a href="https://remotefrontendjobs.com/ckyvm6uyl18254twbwpydu2x4d?from=marketing">JavaScript Engineer (Canada Remote) at Fullscript () (allows remote)</a>, <a href="https://remotefrontendjobs.com/ckyvm6uyl18255twbwy8h1vr8p?from=marketing">Technical Lead, Engineering (Remote Canada) at Fullscript () (allows remote)</a>, <a href="https://remotebackendjobs.com/ckyvm6uyl18256twbwezvt44ao?from=marketing">Senior Ruby Engineer (Remote Canada) at Fullscript () (allows remote)</a>.
 
 
 Right now my job boards are being advertised on all social platforms, including Indiehackers and Polywork which are mainly developer focused.
 
 There’s also a biweekly newsletter going out with the last 8 remote jobs (with featured ones being on top).
 I already had a featured job ad on the Frontend board and the client said that they already had several applicants coming their way from me.
 In terms of engagement - for 14 days their advertisement was clicked more than 150 times.
 
 
 Please let me know if you have any questions and even if you don’t want to feature an ad, I’d love to get any kind of feedback from you! :)
 
 Thank you,
 
 Angel Nikolov

Hi, it's Angel Nikolov again!
	 
	I just wanted to follow up on my last email and ask you if you had time to review the the idea for featuring a job on <a href="https://remotefrontendjobs.com?ref=marketing">https://remotefrontendjobs.com</a> or <a href="https://remotebackendjobs.com?ref=marketing">https://remotebackendjobs.com</a>.
	 
	 
	I would appreciate any kind of feedback!
	 
 Thanks again!

Work with WebGL basics and rendering pipelines to support game client integrations.
Design and build scalable APIs and services to support gameplay, LiveOps tools, and player-facing web features.
Inspect and optimize the performance of services, including latency, throughput, and bandwidth usage, to ensure smooth real-time experiences.
Contribute to platform resilience by analyzing player interactions, preventing exploits (cheating, botting), and hardening systems against bad actors.
Deploy, monitor, and manage applications in a cloud environment (AWS + Github), leveraging CDNs and CI/CD pipelines for efficient content delivery.
Work closely with QA to resolve bugs and deliver high-quality, tested, maintainable code.
Stay up to date with industry trends in Go, modern web frameworks, WebSockets, WebGL, CDN technologies, cloud services, and online gaming infrastructure.

Coinbase Developer Platforms

&nbsp;
Overview:
Ready to be pushed beyond what you think you’re capable of? At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform — and with it, the future global financial system.
To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system. We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high caliber colleagues, and who actively seeks feedback to keep leveling up. We want someone who will run towards, not away from, solving the company’s hardest problems.
 While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported.
 The Coinbase Developer Platform APIs are the easiest way for developers to get started with building crypto applications. Conceived by Coinbase CEO Brian Armstrong, these APIs enable those with no prior knowledge of crypto to begin sending and receiving crypto in as little as 30 seconds. A top priority of the Coinbase Developer Platform (CDP), the CDP APIs encapsulate some of the most cutting-edge technologies in crypto by externalizing Coinbase’s internal services, built over more than a decade of experience. The CDP APIs combine custodial and non-custodial wallets into one clean abstraction, making interactions with the blockchain simple and painless.
 The CDP API team owns both server-side APIs and client-side libraries across different languages. The team seeks a full-stack engineer who is passionate about all aspects of excellent developer experiences: authoring clear and informative documentation, building compelling sample applications, interacting directly with customers to incorporate feedback, architecting delightfully simple SDKs, etc. The engineer must be comfortable operating in both frontend and backend codebases, fluent across a variety of programming languages, and demonstrate both high code velocity and quality simultaneously. The CDP API team consists of some of the most prolific and tenured software engineers at Coinbase, and is excited to ship a game-changing set of APIs and SDKs at breakneck speed.
&nbsp;
 What you’ll be doing (ie. job duties):
⦁ &nbsp; &nbsp;Design, develop, and maintain scalable, secure, and high-performance backend systems for the CDP APIs using Go and Javascript ⦁ &nbsp; &nbsp;Define and maintain clean and conformant HTTP REST API definitions using OpenAPI specifications ⦁ &nbsp; &nbsp;Design, develop, and maintain ergonomic, open-source SDKs to interact with the CDP APIs using Ruby, Typescript, Go, Python, and Java&nbsp; ⦁ &nbsp; &nbsp;Author, publish, and maintain clear and concise documentation, including quickstart and how-to guides, to increase adoption of the Platform APIs and SDKs ⦁ &nbsp; &nbsp;Develop secure and scalable key management systems, packaged as Docker images, to enable crypto wallet functionality across a range of custodial configurations (e.g. self-custodial MPC) ⦁ &nbsp; &nbsp;Work closely with many different teams at Coinbase to externalize their backend services through the Platform APIs, ensuring consistency of concepts, style, and design ⦁ &nbsp; &nbsp;Interface directly with customers to collect their feedback and iteratively improve the CDP APIs and SDKs ⦁ &nbsp; &nbsp;Build compelling sample applications end-to-end using the CDP APIs and SDKs to demonstrate their value and pressure-test the developer experience ⦁ &nbsp; &nbsp;Troubleshoot and debug complex fullstack issues, ensuring stability, reliability, and security ⦁ &nbsp; &nbsp;Participate in code reviews and provide constructive feedback to maintain high code quality standards
&nbsp;
What we look for in you (ie. job requirements):
⦁ &nbsp; &nbsp;5+ years of experience in both backend and frontend software development ⦁ &nbsp; &nbsp;Mastery of JavaScript and Python; experience with TypeScript, Ruby, Go, and Java is a plus ⦁ &nbsp; &nbsp;Excellent verbal and written communication skills, with an eye for detail and a passion for clear, comprehensive developer documentation ⦁ &nbsp; &nbsp;Strong understanding of crypto wallets, including key management, cryptography, and blockchain protocols (e.g. EVM) ⦁ &nbsp; &nbsp;Proven track record of designing, developing, and shipping high-quality, ergonomic client-side libraries and SDKs ⦁ &nbsp; &nbsp;Strong understanding of distributed systems, microservices architecture, and event-driven architectures ⦁ &nbsp; &nbsp;Experience with databases (PostgreSQL, MySQL, MongoDB) and caching systems (Redis, Memcached) ⦁ &nbsp; &nbsp;Solid knowledge of RESTful API design principles and experience with API development and integration ⦁ &nbsp; &nbsp;Familiarity with AWS and containerization technologies like Kubernetes ⦁ &nbsp; &nbsp;Understanding of security best practices and experience with implementing secure coding practices for financial systems ⦁ &nbsp; &nbsp;Crypto-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with dApps or blockchain-based services.
