Vishal V.

TOP RATED PLUS | 6+ YEARS OF EXPERIENCE | FULL-STACK & CLOUD ENGINEERING I help businesses architect, build, and scale production-ready SaaS platforms, secure backend APIs, and high-performance web and mobile applications. With 6+ years of full-stack engineering experience, I specialize in solving complex technical challenges—from system architecture and cloud infrastructure to API integrations, performance optimization, and long-term product development. I work with startups, growing businesses, and established engineering teams that need more than someone who simply writes code. My focus is delivering reliable, maintainable, and scalable software that supports real business growth. 🚀 WHAT I SPECIALIZE IN 1. SaaS Platforms & Full-Stack Architecture Designing and building scalable SaaS applications using React, Next.js, Node.js, NestJS, TypeScript, and PostgreSQL. Expertise includes multi-role applications, enterprise dashboards, authentication, RBAC, subscription management, database architecture, and complex business workflows. 2. Backend Engineering & Scalable API Integrations Building secure, reliable backend systems with REST APIs, microservices, event-driven architecture, webhooks, background jobs, and third-party integrations. Experience with Stripe payments, external API integrations, Redis, SQL/NoSQL databases, and backend performance optimization. 3. Cloud Architecture & DevOps Developing cloud-ready applications using AWS, Docker, CI/CD pipelines, and modern deployment practices. Focused on application reliability, secure configurations, infrastructure efficiency, logging, troubleshooting, and performance improvements. 4. React Native & Cross-Platform Mobile Engineering Developing production-ready iOS and Android applications using React Native and TypeScript, backed by scalable APIs. Experience with mobile architecture, authentication, push notifications, deep linking, third-party SDK integrations, app performance, and App Store/Google Play releases. 5. Application Modernization & Long-Term Engineering Helping businesses improve existing platforms through architecture reviews, codebase refactoring, performance optimization, database improvements, feature development, and ongoing maintenance. I can take ownership of an application throughout its lifecycle—from technical planning to development, production deployment, and continued evolution. 🏗️ MY ENGINEERING APPROACH I believe successful software requires more than delivering features. My approach emphasizes: Architecture & scalability: Modular design, maintainable codebases, efficient APIs, and systems designed for growth. Security & reliability: Authentication, authorization, RBAC, secure API communication, validation, error handling, and data protection practices. Engineering quality: Code reviews, testing, technical documentation, performance optimization, and reliable release processes. Team collaboration: Working closely with product owners, designers, developers, and stakeholders to translate business requirements into technical solutions. Long-term ownership: Maintaining production systems, resolving critical issues, managing technical debt, and continuously improving applications. 💼 SELECTED PRODUCT EXPERIENCE My project experience includes web and mobile products across healthcare, fitness, business operations, and digital platforms. UNify Trials (AstraZeneca): Healthcare mobile application. Bulletproof For BJJ: Published fitness and training mobile application. Steel Dog Heavy Duty: Production web platform. RateMyEstate: Web application and digital platform development. These projects reflect my experience contributing to real-world products with ongoing development and maintenance requirements. 🛠️ CORE TECHNOLOGY STACK Frontend: React.js, Next.js, TypeScript, JavaScript Backend: Node.js, NestJS, Express.js, REST APIs, Microservices Mobile: React Native, iOS, Android Databases: PostgreSQL, MongoDB, MySQL, Redis Cloud & DevOps: AWS, Docker, CI/CD, S3, Cloud Deployments Integrations: Stripe, Firebase, Webhooks, Third-Party APIs, Authentication & RBAC 🤝 LET'S BUILD SOMETHING THAT LASTS Whether you need a senior engineer to architect a new SaaS product, scale an existing backend, modernize your application, or take long-term ownership of web and mobile development, I can help turn complex requirements into dependable software. Let's discuss your technical challenges and build a solution designed for long-term success.
