Hi, I’m Shaneal Prasad - a Full Stack Web & Mobile Developer with 8+ years of professional experience building scalable, high-performance applications. Over the course of my career, I’ve worked on 13+ projects, including 7 delivered independently from start to finish. I’ve partnered with 6+ companies across industries like e-commerce, finance, dentistry, and data analytics, consistently delivering reliable and efficient solutions. What sets me apart I focus on building clean, well-structured, and bug-resistant systems. In my experience, most software issues come from a lack of clarity in design and execution. My approach emphasizes understanding the problem deeply before writing code-this results in faster development, fewer bugs, and long-term maintainability. Notable experience One of my most impactful projects was taking over a failing mobile app for a dentistry company. After their senior developer spent over a year without delivering a working product, I rebuilt the application from scratch-even without prior mobile experience-and successfully delivered it in just 4 months. The final product was stable, performant, and production-ready. I’ve also built advanced systems like a stock market bot and a mobile tele-dentistry platform, demonstrating my ability to handle complex, real-world problems. How I work I take ownership of projects and deliver results I communicate clearly and make thoughtful recommendations I respect your vision while ensuring technical excellence I prioritize speed without sacrificing quality My goal is simple: deliver high-quality software that saves you time and money. Tech stack Web Development React (JavaScript) .NET Core Dapper SQL / MongoDB Bootstrap Mobile Development Flutter React Native Node.js Firebase Cloud & DevOps AWS, Azure, GCP Git, GitHub, Bitbucket, Azure DevOps, SVN Industries I’ve worked with E-commerce Law Dentistry Finance Land Investments Stock Market / Data Analysis I’m currently available for new projects. While my rates may be higher than average, I deliver significantly faster and with higher quality-ultimately reducing your total cost.

Let's connect and discuss how we can transform your CRM into a growth engine for your business.

I specialize in HubSpot CRM integration, API connectivity, and workflow automation, helping businesses create seamless data flow between HubSpot and their core systems. With hands-on experience in designing and implementing CRM integrations, I focus on building scalable solutions that improve lead management, automate sales and marketing processes, and ensure accurate, real-time data synchronization across platforms. My core expertise includes HubSpot CRM setup and customization, API-based integrations, workflow automation, data sync between systems, and CRM optimization for sales and marketing teams. I ensure that HubSpot is not just a CRM, but a fully integrated system that supports end-to-end business operations. I work closely with stakeholders to understand business requirements and translate them into efficient automation workflows and reliable integration architectures. My goal is to reduce manual work, eliminate data silos, and improve visibility across the entire customer lifecycle. If you're looking for a HubSpot CRM Integration Expert who can handle APIs, automation, and system connectivity to streamline your business processes, I can help deliver a robust and scalable solution.

I help businesses turn HubSpot into a fully automated growth system, where leads are captured, routed, followed up, and tracked without manual effort. Most HubSpot setups fail not because of the tool, but because the CRM, CMS, and automation are disconnected. I fix that by building clean, scalable systems that actually support how your business operates day to day. With 5+ years of HubSpot experience, I specialise in building and optimising: CRM systems that reflect real sales processes Automation that removes manual work and missed leads Landing pages that convert traffic into qualified leads CMS builds that are easy for teams to manage and scale What I can help you with HubSpot CRM & Automation Pipeline setup and optimisation Lifecycle stage design Lead routing (including weighted distribution) Automated follow-ups, tasks, and deal creation End-to-end workflow automation HubSpot CMS & Landing Pages Custom HubL themes and modules Figma → HubSpot CMS development High-converting landing page builds Modular, reusable page systems for teams Funnel & Tracking Systems Full funnel setup across CRM + website Lead capture and attribution tracking Dashboard reporting for pipeline visibility Data structure cleanup for reliable reporting Selected Results Compass Pain & Wellness Rebuilt their nurture system into 5 service-specific workflows with behavioural segmentation and a 90-day re-engagement system. Blendi Integrated Shopify with HubSpot and built 15+ automated workflows covering acquisition, retention, and reactivation. Electrify Research Designed a full lead capture + demo booking system with lifecycle mapping, automated deal creation, and follow-ups. SeeChange Built a scalable HubSpot CMS landing page system using custom HubL modules from Figma designs. Cavero Developed executive-level reporting dashboards with automated lifecycle tracking for clean pipeline visibility. Why clients work with me I focus on systems, not just setup I build for scalability and ease of use I reduce manual work and lost leads I prioritise fast, clean implementation without overengineering Most clients come to me because their HubSpot is either underperforming, messy, or not properly connected across CRM, CMS, and automation. I fix that and turn it into a system that supports growth. Ideal clients You should hire me if you need: A complete HubSpot CRM setup or cleanup Landing pages built or optimised in HubSpot CMS Automated workflows and lead routing systems Funnel tracking and reporting dashboards A connected CRM + website + automation system How I work Quick review of your current setup or requirements Identify gaps in CRM, CMS, or automation structure Build or optimise systems in a structured, scalable way Deliver clean, documented, easy-to-use setups Let’s work together If you’re looking for someone who understands both the technical and strategic side of HubSpot—and can build systems that actually run your operations—I’d be happy to help. Send me a message and tell me what you’re trying to improve or build.
