With 9+ years of experience, I help startups and product teams build production-ready frontend systems in React, Vue, Electron, and React Native. I use AI tools like Cursor and Codex to speed up development. Still, the real value is knowing how to keep AI inside safe engineering boundaries: clear requirements, practical architecture, automated tests, code review, and regression checks. My years of team-based development experience help me turn AI-generated output into reviewed, tested, maintainable production code. What I can help you with: 🚀 Fast frontend delivery: from requirement to production with clear milestones 🤖 AI-assisted development: Cursor/Codex workflows for implementation, refactoring, documentation, and test generation 🧪 Testing systems: Playwright scenarios and regression checks for reliable, fast delivery 💳 Payments: Stripe onboarding, checkout, subscriptions, discounts, payouts, and billing management 🖥️ Complex frontend apps: Electron desktop apps, dashboards, internal tools, and admin systems ⚡ Performance optimization: smoother rendering for high-frequency data updates and large datasets Why clients work with me: ✅ Senior frontend experience across React, Vue, Electron, Nuxt, and React Native ✅ Practical AI-assisted workflow without losing control of code quality ✅ Strong testing mindset for critical flows such as payment, onboarding, and checkout ✅ Clear communication, clean code, useful documentation, and predictable handoff ✅ Business-focused mindset: I care about product outcomes, not just code Selected experience: - Built Stripe onboarding, checkout, payment method management, subscriptions, discounts, payouts, and billing interfaces for a production education platform. - Created Playwright test scenarios for critical onboarding and checkout flows. - Supported marketing teams with UTM strategy, GTM tracking, analytics events, and Looker Studio / Databox reporting. - Built and maintained a reusable HTML email template system with 80+ production templates and SendGrid migration support. - Led frontend architecture for a Linux Electron application with high-frequency sensor data rendering, large file uploads, map/tree interaction, and offline deployment constraints. - Mentored frontend developers, reviewed pull requests, selected practical libraries, and built shared UI components. If you need a senior frontend developer who can combine AI speed, test discipline, and production delivery, let’s talk.

The two-second version: I'm an Atlassian Solutions Expert and Full Stack Developer with 11+ years turning complex Jira and Confluence chaos into clean, scalable operations, for everyone from scrappy startups to Fortune 50 giants. 👋 The longer, sit-down version: Great to meet you! I'm Saurabh Gupta. Most of my long-term clients come back to me for one simple reason: I make the complicated feel manageable. Whether that's a sprawling Jira architecture serving 50,000+ users, a Confluence migration pushing past 1TB, or a custom Forge app built from scratch. I've done it, and I've done it without keeping anyone up at night. Over the past decade, I've had the privilege of working deep inside some genuinely challenging environments. Among them: - Enterprise financial institutions (BNY Mellon, Bank of America, Bloomberg) - Fortune 50 and Fortune 500 companies navigating compliance and scale - Fast-growing startups that needed a solid Atlassian foundation from day one - Regulated industries where accessibility and 508 compliance weren't optional One project I'm particularly proud of: I architected a centralized vulnerability data warehouse for BNY Mellon that slashed security reporting cycles from over a week down to under two hours, powered by RabbitMQ for async messaging and custom Java fork-join pools for large-scale data processing. That kind of result, real, measurable and business-changing, is what I'm here for. What makes my work a little different from most Atlassian consultants: I don't just configure your tools, I build inside them. I develop custom Atlassian Forge apps, Java-based plugins, and Marketplace-ready add-ons, which means when your off-the-shelf options run out, I'm just getting started. That rare combination of deep Atlassian administration and full-stack engineering (Forge, Java, RabbitMQ, React, Node.js) is what lets me solve problems others simply hand back. When you work with me, here's what you get: - A partner who listens first and builds second - Solutions that are clean, documented, and built to last (not duct-taped together) - Honest timelines, no surprises, and clear communication throughout Deep expertise across Jira, Confluence, Jira Service Management, Forge app development, Java plugin engineering, automation, migrations, and compliance I also founded Vamhi, where I've published several Atlassian Marketplace plugins. So I understand your ecosystem not just as an admin, but as a builder who has shipped production-grade tools into it and knows exactly what it takes to get them there. My aim is always long-term partnerships. The kind where you stop worrying about your Atlassian environment because you know it's in good hands. If that sounds like what you're looking for, I'd genuinely love to connect. Drop me a message, even if your situation doesn't fit neatly into a category above. Complex and unusual is honestly where I do my best work. Cheers, Saurabh P.S. If you're dealing with a gnarly migration, a compliance deadline, a Forge app you need built right, or an automation problem that has stumped everyone else, those are my favorite kinds of conversations. Don't hesitate to reach out.

Clojure Developers Hiring FAQs

What is Clojure?

Clojure is a dialect of Lisp for the Java Virtual Machine (JVM). It’s a general-purpose programming language designed from the bottom up to support immutable data structures, concurrency, and functional programming. 

Like other members of the Lisp family tree, Clojure code is a valid data structure. This makes Lisp great for metaprogramming, as its statements can be accessed and manipulated like any other data structure. 

How do you hire a Clojure developer?

You can source Clojure talent on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in a Clojure developer.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview Clojure developers. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of Clojure developer you need to complete your project.

How much does it cost to hire a Clojure developer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced Clojure developer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their Clojure development services more competitively. 

Which one is right for you will depend on the specifics of your project. 

How do you write a Clojure development job post?

Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample Clojure development job post titles:

  • Full-stack Clojure engineer needed for a fintech application
  • Seeking a Clojure developer for a web app (MongoDB, PostgreSQL, Angular)
  • Need help with a big data analytics pipeline (Apache Spark and Clojure)

Project description

An effective Clojure job post should include: 

  • Scope of work: From applications to data processing pipelines, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain industries, technologies, or developer tools, mention this here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Clojure developer job responsibilities

Here are some examples of Clojure job responsibilities:

  • Build and deploy functional, highly scalable, secure applications
  • Write performant, well-documented, testable code
  • Collaborate with a team of developers and designers to carry products through the software development lifecycle (SDLC)

Clojure developer job requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in a Clojure developer. Here are some examples:

  • Working knowledge of Clojure
  • Functional programming
  • Application development
  • Project-specific technologies (e.g., Kafka and Spark for high-throughput data streaming)
