GlobalVin - Vehicle Data Engine
Architected a vehicle data engine aggregating datasets from China/USA, providing a high-availability API for dealerships and insurers with sub-200ms latency.
Official portfolio of Sarthak Sharma, focused on modern web apps, cloud infrastructure, and practical product architecture.

About Me
I'm a passionate full-stack developer with expertise in React, Next.js, Node.js, and cloud technologies. Building scalable, user-focused applications with clean code and thoughtful design.
My work combines full-stack development and product design to deliver fast, accessible, and reliable digital experiences. I focus on architecture decisions that keep products easy to scale, simple to maintain, and clear for users. From discovery and interface design to API development, deployment, and performance optimization, I build end-to-end systems that solve real business problems while maintaining strong code quality and long-term flexibility.

A video-based quiz platform that lets teachers (Sifus) create interactive quizzes around YouTube videos and students join using a Dojo Code.
Developed a conversion-optimized corporate platform for cybersecurity services, emphasizing SOC operations and threat monitoring.
A platform offering CAIE revision notes, mock exams, topical videos, and tutor support focused on IGCSE and A Level students.
I work across frontend, backend, databases, cloud deployment, and developer tooling to ship products that are both practical for teams and delightful for users. The stack below reflects tools I use regularly in production work, freelance collaborations, and rapid prototyping.
My focus is not just choosing modern technologies, but making sure each part of the system has a clear role: fast interfaces, reliable services, clean data flow, and predictable release pipelines.
How I Work
Great digital products are usually the result of clear decisions, not accidental complexity. I begin projects by understanding business goals, user context, and delivery constraints. That means translating broad ideas into specific outcomes: faster onboarding, better conversion, lower support load, or more predictable internal workflows. With those outcomes defined, I shape the architecture and user flows around what matters most.
In the design and implementation phase, I balance speed with long-term maintainability. On the frontend, I prioritize readability, accessibility, and performance budgets from the beginning instead of treating them as cleanup tasks. On the backend, I design APIs and data models for clarity so teams can extend features without rewriting core logic every few months. Whether the product is a client-facing platform or an internal operations dashboard, the objective is the same: reduce friction and increase confidence for everyone using it.
I also care deeply about collaboration quality. Product and engineering teams work better when progress is visible and decisions are documented. I keep communication concise, flag risks early, and break work into milestones that can be reviewed and shipped incrementally. This approach helps teams avoid long, stressful release cycles and instead build momentum through steady, measurable improvements.
After launch, I continue to support optimization through performance audits, UX refinements, and technical debt reduction. Shipping is a milestone, not the finish line. Products grow best when teams can observe user behavior, iterate quickly, and make data-informed changes without destabilizing the codebase.

Faster page load
45%
How to achieve: audit Lighthouse/Web Vitals, optimize images, defer non-critical scripts, then use caching and code-splitting.
Better Core Web Vitals
38%
Steps: stabilize layout to reduce CLS, improve LCP with optimized hero content, and lower INP by simplifying heavy interactions.
Stable API response time
31%
Approach: profile endpoints, fix slow queries/indexes, add smart caching, and monitor p95/p99 latency after each release.
I help startups and growing teams ship modern web products with a strong balance of performance, usability, and maintainability. Each project starts with clear goals, user-focused design, and a technical plan that supports growth from day one. I prioritize robust frontend experiences in React and Next.js, scalable backend services in Node.js, and practical cloud infrastructure that keeps releases stable and predictable.
If you need full-stack development, visual design direction, or a partner to improve product quality and delivery speed, I’m open to new collaborations. My process emphasizes transparent communication, measurable outcomes, and continuous iteration so teams can ship confidently.
