About Me

Hi I’m Tanveer Ahmad. I work as a software developer and architect. I’ve contributed to projects in publishing, eCommerce, insurance, banking, and manufacturing with a focus on ERP and CMS solutions.

I mainly work with .NET (C#), JavaScript/TypeScript, ASP.NET MVC and Web API. For data access I use Entity Framework, Dapper and ADO.NET.

On AWS and Azure, I design systems with attention to availability, scaling and security. I use architecture styles and patterns such as Microservices, N‑Tier, Event‑Driven, Hexagonal (Ports & Adapters) and CQRS when they fit.

I also explore AI and data science and help teams learn when needed.

My aim is to build dependable software and keep learning.

Quick Highlights
  • 20+ years across domains
  • AWS & Azure cloud-native design
  • Architecture styles & patterns
  • Technical leadership & mentoring
  • AI & data-driven solutions

System Design with AWS

Examples of AWS-based designs I commonly use.

Architecture Pillars
  • Reliability: Multi-AZ, health checks, automated failover
  • Scalability: Auto Scaling, serverless patterns, managed services
  • Security: IAM least-privilege, KMS, VPC isolation, WAF
  • Performance: Caching, async processing, global edge
  • Cost: Right-sizing, Spot, lifecycle policies, tagging
Services & Patterns
  • Compute: EC2, ECS/Fargate, EKS, Lambda
  • Integration: API Gateway, SQS/SNS, EventBridge, Step Functions
  • Data: RDS/Aurora, DynamoDB, S3, ElastiCache, OpenSearch
  • Networking & Edge: VPC, ALB/NLB, Route 53, CloudFront
  • Ops: CloudWatch, X-Ray, CloudTrail, CodePipeline/Deploy
Reference Architectures
  • Microservices on ECS/EKS with service discovery and observability
  • Event-driven: Lambda + SQS/SNS/EventBridge + Step Functions
  • CQRS with Aurora/DynamoDB, ElastiCache for low-latency reads
  • Global delivery: S3 + CloudFront with OAC and WAF
Observability & Cost
  • Dashboards/alerts, tracing, and logs with CloudWatch/X-Ray
  • Blue/green and canary releases with CodeDeploy
  • Cost Explorer budgets, tagging, and rightsizing

Core Skills

  • .NET / C# development
  • JavaScript & Type Script
  • ASP.NET WebSites, ASP.NET MVC, ASP.NET Web API (Framework & Core)
  • Data access: Entity Framework, Dapper, ADO.NET
  • Cloud architecture & services (AWS & Azure) for high availability, auto-scaling, fault tolerance, security
  • Solution architecture & technical leadership
  • Multi-domain experience: Publishing, eCommerce, Insurance, Banking, Manufacturing, Gaming, ERP, CMS
  • Architecture styles & patterns; component-level design patterns
  • AI & Data Science: training, upskilling, data-driven solutions, intelligent systems

Architecture Styles & Patterns

Architecture Styles / Patterns (system-level)
  • Layered (N-Tier) Architecture: Clear separation of presentation, business logic, data access.
  • Microservices Architecture: Decomposing into independent services for scalability and agility.
  • Event-Driven Architecture: Enabling asynchronous, decoupled communication for high throughput.
  • Hexagonal (Ports & Adapters): Isolating core business logic from external dependencies.
  • Service-Oriented Architecture (SOA) for enterprise integration.
Design Patterns (component / interaction-level)
  • Creational: Abstract Factory, Builder, Singleton, Prototype
  • Structural: Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy
  • Behavioral: Chain of Responsibility, Command, Observer, Strategy, State, Template Method
  • Integration / fault-tolerance: Circuit Breaker, Strangler Fig, Publish/Subscribe, Retry

Cloud & Infrastructure Expertise

  • High-availability setups (multi-region/multi-zone, failover, redundancy)
  • Auto-scaling (elastic compute, serverless functions, containers)
  • Fault tolerance (distributed systems, retries, circuit breakers, event queues)
  • Security best practices (IAM, encryption, network isolation, threat mitigation)
  • Infrastructure as Code (IaC) and automated deployment/CI-CD pipelines
  • Monitoring, logging, observability and performance tuning in the cloud

Selected Projects / Domains

  • eCommerce: Architected/led development of scalable platforms, payment integration, large-scale traffic.
  • Insurance & Banking: Enterprise systems for underwriting, policy administration, financial workflows.
  • Manufacturing: Process automation, ERP integrations, event-driven real-time systems.
  • Gaming & Publishing: Interactive services, content delivery, high-availability and global scaling.
  • ERP & CMS Solutions: Modular architecture, integrations, custom workflows, maintainability.
  • AI & Data Science Initiatives: Training, mentoring, data-driven solutions and upskilling.
