Architecting scalable APIs, cloud workflows & resilient databases.
Hi, I'm Divy Patel. I specialize in high-throughput REST APIs, SQL, AWS S3/SQS decoupled pipelines, and secure document abstraction architecture.
Scaling property verification, title search workflows, and public notice intelligence pipelines across pan-India bank integrations.

Awarded at PropLegit for backend reliability
Engineering backend systems built for resilience, not just demos.
I am a Jr. Node.js Developer at PropLegit Global in Ahmedabad, Gujarat. My daily work centers on building production-grade enterprise backend services, designing transaction-safe database workflows, and orchestrating cloud infrastructure.
Rather than assembling superficial mockups, I focus on the critical mechanics of software: ensuring databases remain ACID-compliant during large batch operations, streaming files directly to cloud storage without exhausting server RAM or leaking AWS endpoints, and writing clean, maintainable REST APIs consumed by multi-tier corporate modules.
One of my foundational contributions at PropLegit has been the company-wide MaskID document architecture—a security layer that handles file uploads, storage, and streaming from AWS S3 without exposing internal S3 URLs to clients. This architecture was standardized as a reusable security pattern and adopted across the company's enterprise products, services, and modules.
My engineering approach emphasizes predictability: strict input validation, idempotent asynchronous consumers (via AWS SQS), optimized indexing on relational stores (SQL Server, MySQL, Postgres), and structured error handling.
Core Engineering Tenets
Zero Trust Document Access
Never leak direct S3/blob URLs. Stream files through verified tokenized proxies with explicit permission validation.
Atomic Transaction Safety
Utilize SQL Server queries, stored procedures and rollback handlers to prevent orphaned records in multi-table workflows.
Idempotent Queue Workers
Consume messages with AWS SQS; only delete messages after database commit verification, ensuring zero record loss.
Measurable Query Tuning
Refactor query plans, apply appropriate composite indexes, and reduce latency on heavy report generation queries.
Professional Experience & Enterprise Impact
Direct engineering contributions to production applications, workflow automation, and cloud services.

Technical Contributions
- Created and standardized a company-wide secure document-management architecture using MaskID and AWS S3, eliminating direct bucket URL exposure and establishing a reusable security pattern across company products.
- Architected enterprise workflow engines driven by bank/service/state flags, migrating dynamic status resolution from complex stored procedures into a clean, testable API layer.
- Strengthened production engineering and system reliability through log-driven root-cause analysis (RCA), identifying application, database, and integration bottlenecks and delivering synchronized multi-tier fixes.
- Improved backend performance and scalability through SQL query optimization, composite indexing, and caching, particularly across high-volume data grids, reporting pipelines, and bulk upload processes.
- Enhanced API security by detecting production enumeration attempts and implementing MaskID pattern validation, rate limiting, and CORS allowlisting.
- Modernized legacy PHP business workflows by migrating core services to Node.js, Express, and Angular while preserving business parity and improving long-term maintainability.
- Refactored AWS SQS queue processing with separated queues, centralized configuration management, per-application error logging, and manual re-queue tooling with zero message loss.
