I'm a backend engineer who thrives on turning complex business requirements into clean, maintainable systems. My day-to-day revolves around designing APIs, architecting services, and making sure things don't break at 3 AM.

• Working on Smart Mailbox Management System, an end-to-end mail operations platform
• Built multi-tenant SaaS platforms handling payments, invoicing, messaging, and customer management
• Designed and shipped RESTful APIs serving production workloads with Django REST Framework

• AWS Solutions Architect, designing and deploying production workloads across EC2, Lambda, S3, RDS, ECS, CloudFront, API Gateway, SQS, SNS, and more
• Building AI/ML workloads on AWS with Amazon Bedrock, RAG architectures, and SageMaker AI for model deployment and monitoring
• Designing data pipelines with Glue, Athena, Kinesis, and Redshift for ETL/ELT and analytics workloads
• Experienced with cloud-native architectures across AWS and Azure with containerized microservices

A multi-tenant SaaS portal for managing properties, subscriptions, and financial operations with full Qoyod ERP integration.

• 252+ REST API endpoints (Django REST Framework) with OpenAPI docs via drf-spectacular
• Subscription billing automated monthly invoicing, partial-period prorating, multi-invoice payment application, receipt generation
• Qoyod ERP integration bidirectional sync for contacts, invoices, and payment receipts
• WhatsApp Business API payment reminders, confirmations, bulk messaging with template management
• Event-driven sync transactional outbox pattern (SNS/SQS) for cross-app data synchronization
• Lambda automation daily invoicing, offer expiry, health monitoring, payment processing via EventBridge

• Infrastructure ECS Fargate, RDS, ElastiCache, S3, Lambda, CloudWatch, Terraform IaC, GitHub Actions CI/CD

A full-stack operations app for managing building cleaning visits, integrated with the Portal via event-driven architecture.

• Mobile-first frontend HTMX + Alpine.js + Tailwind CSS with PWA support
• Visit lifecycle recurring schedules (weekly/monthly/quarterly), priority ordering, automatic generation, video-required completion
• Real-time features SSE notifications, building-based staff chat (text, images, voice notes, reactions), Kanban board with weekday columns
• Video pipeline direct S3 upload with CloudFront signed URL delivery, iOS-compatible record/gallery options
• Event-driven sync SQS consumer for Portal data + periodic reconciliation with drift detection and correction
• WhatsApp integration customer reminders via Portal API from the building board
• Role-based access Admin (full panel + board), Cleaner (assigned regions), Customer (own buildings)
• Infrastructure ECS Fargate, RDS Proxy, ElastiCache, S3, CloudFront, SQS, WAF, Terraform IaC

Both systems follow a service layer architecture, business logic lives in dedicated service classes, keeping views thin and ensuring consistency between template views and API endpoints.
