✌✌Top Rated Professional + 100% Job Success Ratio✌✌ If 15 years as a lead developer turned solution architect sounds amazing, I am still learning while keeping a keen watch on technological advances. From SAAS-based business automation (ERP, CRM, industry-specific applications) to building a portfolio in niche domains like: 👉👉Healthcare and Logistics, Aviation, and AI, I have worked as a freelancer, team lead, and technical advisor as and when required. **Though I love developing applications from scratch, I have an ample amount of work that includes** ✔ Working in collaboration with remote teams, offsite and onsite (Global Clients, Australian/US clients) ✔Migration of legacy applications as per Object Oriented Design, intuitive Single Page Application (SPA) interface with Angular 6, .NET Core, SQL SERVER 12/14, and Azure services. ✔Data analytics: PowerBI, SSRS, Tableau, DevExpress Reporting, Upscaling existing applications (features and performance enhancement, database management, etc.) ✔Entity Framework, ADO.NET, and API/ Microservices development **Withstanding a decade-long technology advancement, there is more to what I can offer if you are a well-established business having a large customer base.** 👉Setting up your cloud infrastructure with Azure and AWS to avail shared and multi-tenant services so that you can handle unpredictable changes in user demand and balance across servers. 👉 Set up proper logging and monitoring to catch any performance problems or errors before they affect your business negatively. 👉 Set up continuous integration or track down and eliminate bugs to eliminate the possible human errors while deploying the new versions. Apart from this, on-time delivery, a quick turnaround, and no-fuss behavior have earned me a good reputation and consistent client collaborations/Projects worth a few weeks to years🤗 And what's better than client feedback?
