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.

Full-Stack Engineer who builds scalable web apps that hold up in production — Angular & React on the front, Java Spring Boot & Python (Django/Flask) on the back. 100+ projects delivered, 0 missed deadlines. WHAT I BUILD → Enterprise-grade REST APIs and microservices with Java Spring Boot → Dynamic, responsive front-ends with Angular and React → Lightweight Python backends with Django and Flask → Automated web scrapers that extract, clean, and deliver structured data at scale → Database design & optimization — PostgreSQL, MySQL, MongoDB TECH STACK Frontend: Angular | React | JavaScript (ES6+) | HTML5 | CSS3 Backend: Java Spring Boot | Python Django | Flask Databases: PostgreSQL | MySQL | MongoDB Scraping: BeautifulSoup | Selenium | Scrapy | Playwright Tools: Git | REST APIs | Docker | Postman HOW I WORK I don't just write code — I ask what the feature is actually for before touching a keyboard. That means fewer revisions, cleaner architecture, and software that solves the real problem, not just the surface one. You get: ✔ Clean, documented, maintainable code ✔ Regular updates — you'll never be left wondering where things stand ✔ Honest timelines — I'd rather under promise and overdeliver ✔ A developer who thinks about your business, not just the ticket GOOD FIT FOR - SaaS platforms and internal tools - REST API development and third-party integrations - Data scraping pipelines and automation - Full-stack builds from MVP to production - Migrating or refactoring legacy systems If you're building something and need a developer who gets it done cleanly — send me the brief.
