Database Development Projects in LahoreDatabase Development Projects in LahoreOracle to Amazon RDS PostgreSQL
Designed and Implemented a secure, scalable architecture to migrate an on-prem Oracle database to Amazon RDS for PostgreSQL.
Data Flow: Modeled end-to-end flow, used AWS Glue (SCT) for schema conversion and DMS for full-load and CDC. Stored artifacts in S3 and loaded into RDS.
Services: Glue for conversion, DMS for Migration , S3 for artifacts, and RDS as target.
Security: IAM roles with least privilege, KMS for encryption at rest.
HA & DR: Architected in us-east-1 with Glue, DMS, RDS, S3, and monitoring via CloudWatch. 🚀 Building a Graph-Based Fraud Detection System with Neo4j
A single transaction may look normal. Its connections can tell a different story.
I’m building a learning project using Neo4j and Cypher to explore relationships between customers, accounts, transactions, and devices—and flag patterns worth investigating.
🔍 Patterns I’m exploring:
• Multiple customers sharing the same device
• Unusually large transactions
• Rapid transactions within a short period
• Multiple accounts sending money to one account
• Circular transfers between connected accounts
The focus is explainability: showing the relationships behind each flag so the suspicious activity is easier to understand.
Through this project, I’m strengthening my graph data modelling, Cypher queries, and rule-based detection skills.
Next: FastAPI integration, transaction risk scores, fraud alerts, and an interactive monitoring dashboard.
🛠️ Currently a learning prototype, with more updates coming as I build.
What would you investigate first: shared devices or circular transfers?

I handled everything from database design to UI and workflow logic. Features include dynamic listings, availability status, contact forms, and a fully responsive layout for desktop and mobile.
Built using repeating groups, conditional visibility, dynamic filtering, and multi-role data handling — core Bubble skills clients look for. Eyecon | Optical Management System
Eyecon is an intelligent ophthalmic clinic and optical retail management
system designed specifically for optometrists, ophthalmologists, and eyewear
retail stores. The platform combines clinical eye refraction management with
optical product inventory and a fully integrated point-of-sale environment,
enabling clinics and optical shops to manage patient prescriptions, eyewear
products, and sales operations from a single centralized system.
The system maintains a
complete history of patient eye prescriptions, including refractive
measurements such as Sphere, Cylinder, Axis, and additional optical parameters
used in professional eye testing. Eyecon incorporates intelligent logic to
analyse stored prescription data and assist practitioners in determining
appropriate lens power values based on previous refraction records and standard
ophthalmic practices.
Beyond the clinical
environment, Eyecon includes a comprehensive optical retail module that manages
frames, ophthalmic lenses, contact lenses, sunglasses, and eyewear accessories.
The integrated inventory engine tracks product availability, product specifications,
and stock movement while seamlessly connecting with the POS module used for
retail sales.
The POS module allows
optical stores and clinics to sell eyewear products while automatically linking
patient prescriptions with the appropriate lenses and frames. Sales
transactions update stock levels in real time while maintaining accounting
integration for financial tracking.
Built as a cloud-connected
Windows desktop application, Eyecon allows multiple branches or clinics to
operate with a centralized database hosted on a remote server. This
architecture ensures secure data storage, synchronized operations, and
accessibility across different clinic locations.
Key capabilities
include:
• Patient eye
refraction record management
• Intelligent prescription analysis and lens power assistance
• Optical product inventory management
• Integrated optical retail POS system
• Prescription-to-product workflow automation
• Stock tracking for frames, lenses, and accessories
• Accounting and financial integration
• Cloud-connected multi-clinic architecture
Eyecon bridges the gap
between clinical ophthalmic practice and optical retail operations,
providing a unified platform that improves efficiency for eye clinics and
optical businesses
