The Challenges & Our Solutions
Large Attachments
Uploading large Base64 files caused Oracle CLOB issues and blocked users.
Chunked Storage
Split files into 2,500-character chunks, store in a table, and reassemble later.
Performance Drop
Large uploads locked Oracle resources, reducing concurrency.
Optimized Inserts
Storing smaller chunks improved efficiency and allowed multiple users to upload simultaneously.
Oracle Downtime
Requests hung if Oracle was unavailable.
Retry Queue
Failed requests moved to RabbitMQ Retry Queue and retried automatically when Oracle returned.
System Responsiveness
Users had no feedback during Oracle outages.
Immediate Acknowledgment
Backend returned “Request queued” immediately while processing retries later.
Key Features
Efficient Large File Handling
Large attachments (images, documents, etc.) are split into manageable 2,500-character chunks, ensuring Oracle can process uploads without performance degradation or blocking.
Optimized System Performance
Chunk-based storage and processing reduce resource locking in Oracle, allowing multiple users to upload and access data concurrently without slowdowns.
Resilient Retry Mechanism
If Oracle is unavailable, requests are automatically moved to a Retry Queue. They are retried seamlessly once Oracle is back online, preventing data loss.
Uninterrupted User Experience
Users receive immediate acknowledgment (e.g., “Request queued”), keeping the system responsive even during outages, while ensuring all requests are eventually processed.

CodeChain helped us transform our MVP into a production-ready SaaS platform. Their engineers brought structure, clean code, and speed to the table. They didn’t just execute tasks — they contributed ideas and solutions that improved the final product. The platform now runs smoother, scales better, and looks more polished than we imagined. Great team, great results.
Anil Tarpara
Owner, MAK Tech
CodeChain built us a custom applicant tracking system that fit our hiring process perfectly. The dashboard is intuitive, the filters are smart, and we’ve cut our screening time in half. Their team was quick to understand our needs and delivered without a single delay. It’s rare to find a dev partner who gets both UX and business logic.
Rakesh Patil
Owner, Battle Village
Our online store couldn’t keep up with growing demand. CodeChain built a custom e-commerce backend that’s fast, scalable, and easy for our team to manage. They also integrated it with inventory systems and payment gateways flawlessly. Sales are up, downtime is gone, and our customer experience is better than ever. Professional, precise, and reliable.
Karan Bengani
Owner Kracknow
We needed to eliminate manual workflows across several departments. CodeChain designed a suite of internal tools that automated reporting, approvals, and document management. The time saved has been enormous — our teams are now focused on strategy instead of repetitive tasks. They’re technical experts who genuinely care about business outcomes.
Sagar Vaghasiya
Owner ZLine Laser technology
CodeChain built a custom mobile app for our large-scale conference, including ticketing, live updates, and networking features. Attendee feedback was overwhelmingly positive, and we were able to manage everything from a single admin dashboard. They delivered exactly what we needed, on time and within budget. Looking forward to working with them again.
