You have an idea. I've shipped it — 4 AI SaaS products, live and running. Aptiview.ai (AI-powered interview scheduling), MarineFlow.ai (AI-driven maritime operations platform), Gocontinuum.ai and Pitchster.ai — built by me, from concept to deployment. That's not portfolio decoration. That's proof I can own a product end-to-end. I'm a certified Salesforce Platform Developer I & App Builder with 20+ years of software experience and a 100% Job Success Score across every project I've delivered on Upwork. What I build: → SaaS MVPs — 0 to live, fast and clean → AI/ML integrations — OpenAI, LLMs, NLP, GenAI features → Salesforce — custom development, integrations, CPQ, APEX, Lightning → Full-Stack — React, Node.js, Python, MERN/MEAN, REST APIs How I work: I communicate every day. I flag problems early, not after deadlines. I write code you can maintain and hand off — not spaghetti that only I can fix. As a co-founder of OmniRises Technologies, I understand business goals, not just technical specs. Who I work best with: Founders building their first SaaS, companies integrating AI into existing products, businesses needing Salesforce built or fixed properly, and teams who want a senior technical partner — not a vendor. I hold an MCA from NIT (National Institute of Technology) and have led projects at DXC Technology and co-founded two tech companies. My response time is under 4 hours. Message me with your brief — I'll tell you within the day if I'm the right fit and what it'll take.

If you're building a SaaS platform, modernizing a legacy .NET system, or need an experienced architect who can design multi-tenant applications that are secure, scalable, and maintainable you're in the right place. I'm Mayur, a Microsoft Certified .NET Full Stack Developer with 12+ years of experience building enterprise-grade web applications. I specialize in ASP.

Hi, I am Vishnu, a Senior Full-Stack Developer with 10+ years of experience in Electron, Tauri, AI/ML, SaaS development, MVP development, automation, and cross-platform desktop applications. I build reliable software products using Electron, Tauri, React, Next.js, TypeScript, Node.js, Python, FastAPI, OpenAI, Claude, LangChain, RAG, vector search, and modern cloud technologies. Most of my work sits at the intersection of desktop app development, full-stack engineering, AI integration, workflow automation, and SaaS product development. I help startups, SMBs, and product teams build applications for Windows, macOS, Linux, and the web, from early-stage MVPs to production systems used by real businesses. 🎯 𝐀𝐫𝐞𝐚𝐬 𝐈 𝐜𝐚𝐧 𝐡𝐞𝐥𝐩 𝐲𝐨𝐮 𝐰𝐢𝐭𝐡: 𝐃𝐞𝐬𝐤𝐭𝐨𝐩 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 Electron development, Tauri development, desktop app development, cross-platform apps, desktop SaaS clients, offline-first tools, system tray apps, multi-window applications, file managers, local database apps, background services, auto-updaters, code signing, native OS integrations, Windows apps, macOS apps, and Linux apps.

I care about building software that is not only functional, but maintainable. Desktop apps especially need proper architecture, secure local storage, smooth updates, reliable packaging, installer setup, code signing, and clean release flows. AI features need to be useful, controlled, and properly connected to the product, not added as a gimmick. For Electron and Tauri projects, I can help with the full development cycle: architecture, UI, backend APIs, local storage, native features, packaging, installer setup, auto-updates, code signing, debugging, performance optimization, and production release. For AI projects, I can help design and build practical AI workflows, including RAG chatbots, document search, AI assistants, AI agents, data extraction tools, internal automation, and LLM-powered product features. ☑️ 𝐒𝐨𝐦𝐞 𝐨𝐟 𝐦𝐲 𝐫𝐞𝐜𝐞𝐧𝐭 𝐰𝐨𝐫𝐤 𝐢𝐧𝐜𝐥𝐮𝐝𝐞𝐬: • Cross-platform Electron apps for Windows, macOS, and Linux • Tauri apps with lightweight performance and secure local storage • AI-powered document search and Q&A systems using RAG • Desktop SaaS clients with authentication, billing, and API sync • Internal automation tools connected to CRMs and third-party APIs • Enterprise reporting dashboards with offline-first support • File management and synchronization tools with OS-level integrations • Code signing, auto-update, and release pipeline setup • Full-stack SaaS MVPs for startups and SMBs • OpenAI and Claude integrations inside existing applications • Admin dashboards, client portals, and internal business tools • API integrations, Stripe billing, CRM sync, and webhook automation 🏆 𝐖𝐡𝐚𝐭 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐬𝐚𝐲 𝐚𝐛𝐨𝐮𝐭 𝐦𝐞 🏆 ⭐⭐⭐⭐⭐ “Absolute expert with great communication skills, we will work together soon again.” ⭐⭐⭐⭐⭐ “Vishnu is an exceptional developer whose work consistently exceeds expectations.” ⭐⭐⭐⭐⭐ “Very knowledgeable and went above and beyond to meet our requirements.

Over 8+ years, I've delivered SaaS products where I led technical direction end-to-end as a Full Stack Developer. My work typically involves designing backend architecture in Node.js and Express, building scalable APIs, and pairing them with clean React.js, Next.js or Angular frontends. I don't split roles, I architect, build, test and ship complete systems myself. What I focus on as a Full Stack Developer: My day-to-day as a Full Stack Developer means thinking about both layers simultaneously. A robust backend doesn't matter if the frontend can't consume it cleanly. A beautiful interface breaks if the API doesn't scale. So I design backwards from user workflows and forwards from infrastructure constraints. When you hire a Full Stack Developer like me, you're not paying for coverage across two domains, you're getting someone who treats the entire system as one cohesive problem. That changes how I approach every decision, from schema design to component architecture. Core strengths as a Full Stack Developer: I regularly work on Full Stack Developer projects that require: Multi-tenant SaaS architectures with role-based access and permissions Complex internal dashboards and workflow tools for teams Ecommerce platforms and custom Shopify app builds Payment integrations, ledger systems, and financial workflows Third-party API integrations and real-time data sync pipelines AI-powered backend features, not just prompt wrappers, but thoughtful integration into actual product workflows Scalable query logic and database optimization from a Full Stack Developer perspective On the backend side, where most of my time sits as a Full Stack Developer, I design services in Node.js and Express, manage PostgreSQL and MongoDB databases, handle background jobs and async workflows, and deploy everything on AWS infrastructure (EC2, S3, CloudFront, Route 53). TypeScript is standard across my Full Stack Developer work. I approach backend design the way a Full Stack Developer should: not in isolation, but thinking about how frontend code will consume it, how operations teams will monitor it, and how it'll perform under real load. On the frontend side, as part of being a Full Stack Developer, I build interfaces in React.js, Next.js or Angular depending on what the product needs. I prioritize performance, accessibility and maintainability over trendy patterns. Working as a Full Stack Developer on the frontend means understanding that component choices cascade into backend implications.
