About Me
I am a Computer Science graduate from IIIT Vadodara with 1.5+ years of work experience designing robust backend systems, optimized APIs, and efficient database architectures. Alongside core system logic, I build fluid cross-platform mobile applications with Flutter and create clean, high-performance web frontends using React and Next.js.
I believe engineering is all about planning, designing, and executing.
Work Experience
Production engineering experience across distributed backend sync systems, API development, and cross-platform mobile app launches.
Software Engineer Intern
Intelligentia Labs•Jan 2025 – May 2025
Backend & Systems
Key Achievements & System Deliverables
- Reduced server load by 30% by engineering sync pipelines with batch processing and socket communication, which led to stable performance across high concurrency environments.
- Achieved sub-50ms retrieval across 10,000+ records by architecting an offline-first data layer with local-first synchronization and conflict resolution, ensuring zero downtime during network failures.
- Integrated OpenAI APIs for intelligent content processing and generation, enhancing application functionality through real-time AI-powered interactions and automated workflows.
- Improved end-to-end system throughput by redesigning multi-tier data transfer workflows, reducing infrastructure overhead and maintaining performance under variable network conditions.
Engineering Challenges
- Maintaining data consistency across offline devices while managing intermittent network connectivity.
- Optimizing query performance for large datasets (10k+ records) on low-end mobile hardware.
Technical Ownership
Spearheaded the integration of OpenAI APIs into the in-app chatbot, defining the architecture for secure API handling.
Engineering Retrospective"Initially, I attempted to sync records individually, which caused significant battery drain and server overhead. I pivoted to an idempotent batch-sync architecture, which taught me the value of minimizing network round-trips in distributed systems."
Mobile Intern
Kartavya Technology Pvt. Ltd•May 2024 – Jul 2024
Mobile Engineering
Key Achievements & System Deliverables
- Developed an MVP Flutter interface for health record management and data visualization.
- Collaborated with the backend team to integrate over 30+ RESTful APIs.
- Maintained a Mean Time To Repair (MTTR) under 1 day during pre-production phases.
Engineering Challenges
- Building from scratch in a fast-paced 'founding' environment where requirements shifted rapidly.
- Ensuring sub-1 day MTTR while managing global state for complex health metrics.
Technical Ownership
Led the Flutter development and release pipeline, successfully publishing the first two versions of the app to the Google Play Store.
Engineering Retrospective"Coming from a solo-project background, I initially struggled with version control and documentation in a team setting. If I were to do it differently, I would establish a strict CI/CD pipeline and automated tests from day one to avoid manual pre-production debugging."
Leadership & Community
Community initiatives where Uday organized events, mentored junior engineers, and led Flutter workshops for Google Developer Student Clubs.
Flutter Lead
Google Developer Students Club (GDSC), IIITV•Aug 2023 – Aug 2024
Community Leadership & Mentorship
Key Responsibilities & Community Impact
- Led the Flutter wing of the campus developer community, mentoring 100+ students in mobile app development.
- Organized mobile-development bootcamps and hands-on workshops.
- Managed projects for student-led mobile applications.
Challenges Overcome
- Bridging the gap between varying skill levels within the community.
- Balancing high-level architecture mentoring with low-level debugging for beginners.
Community Execution
Directly managed technical sessions and assigned tasks to sub-teams, ensuring all workshop projects were completed on time.
Leadership Reflection"I learned that leadership is less about having all the answers and more about creating an environment where people feel safe to ask questions."

Locaura — Hyperlocal Marketplace System
Solo Full-Stack Architect & Lead Mobile Developer
Active Production•Production-Grade Monolith & Dual Apps
Locaura is an end-to-end hyperlocal commerce platform designed to bridge the gap between local brick-and-mortar fashion retailers, consumers, and delivery partners. The platform orchestrates a complex, three-actor workflow (Consumer, Retailer, and Rider) supported by a high-performance modular monolith REST backend and two tailored Flutter mobile applications.

Core Engineering Spheres
Systems & Backend
Modular Monolith Architecture
Architected and implemented a Node.js/TypeScript REST API. Strictly enforced module boundary rules (where modules import only from a shared/ layer and never directly from each other) to ensure a clean codebase prepared for future microservices extraction.
Geospatial Discovery
Built a high-performance retailer discovery engine utilizing MongoDB $geoNear query aggregates with a 2dsphere index to locate and rank active retailers within a dynamic coordinate radius.
State Machine Integrity
Designed a strict Order State Machine governed by an allowedTransitions map at the service layer, preventing invalid state transitions (e.g., bypassing confirmation or assignment steps) and protecting DB consistency.
Multi-Actor Authorization
Implemented a single JWT authorization framework embedding distinct role claims (consumer, retailer, rider) enforced by dedicated middleware guards.
Live Product Interface
End-to-End Hyperlocal App
Production-grade interface designed and engineered for the Locaura hyperlocal marketplace.
Engineering Milestones
Key Technical Achievements
100%Transaction Accuracy
Zero-Trust Webhook Ingestion
Designed a system capable of handling highly redundant webhook events from Razorpay without database write duplication, ensuring 100% financial transaction accuracy.
<500msSearch Latency
Sub-Second Location Discovery
Achieved ultra-low latency retail search by indexing geolocation coordinates and caching geospatial results in Redis with a 5-minute TTL invalidation strategy.
ReadyFor Microservices Scale
Decoupled Monolith Ready for Scale
Successfully separated the application logic into distinct domains (Consumer, Retailer, Rider, Payments, Notifications), ensuring the platform can scale to microservices with zero DB refactoring.
