Fahim Hasan
AWS Certified Solutions Architect – Associate · Full-Stack Engineer · Cloud, AI & Platform Builder
I design and build scalable systems on AWS and across the full stack — web, mobile, containers, and AI-powered workflows — from interface to infrastructure.
Proficient across major cloud ecosystems
I design and ship production workloads on AWS, Azure, GCP, and DigitalOcean— from networking and compute to data stores, observability, and cost-aware operations. Same architectural discipline, adapted to each platform's primitives and best practices.
Stack I build and run in production every day
From containers and orchestration to CI/CD, infrastructure as code, messaging, and observability — the same tools I use to design, deploy, and operate reliable systems for teams and customers.
Systems Thinking. Business-Aware Engineering.
I don't just build applications — I design complete systems that span user experience, backend services, cloud infrastructure, deployment pipelines, and intelligent integrations.
With over 11 years of hands-on engineering and architecture experience, I bring a rare combination of deep technical expertise and strategic product thinking. Every system I design is built for scale, resilience, and long-term maintainability.
From startups to enterprise platforms, I operate across the full stack — frontend frameworks, backend APIs, cloud infrastructure, containerized deployments, mobile applications, and AI-powered workflows.

Multi-Cloud Enterprise Platform
PROBLEM:Legacy monolith couldn't scale to handle growing user demand and multi-region requirements.
SOLUTION:Designed and delivered a microservices architecture deployed across AWS ECS with event-driven communication, auto-scaling, and multi-region failover.
AI-Powered Analytics Dashboard
PROBLEM:Business teams needed real-time insights with natural language querying over complex datasets.
SOLUTION:Built a full-stack analytics platform with OpenAI-powered natural language to SQL, real-time dashboards, and automated report generation.
Logistics Management System
PROBLEM:Manual logistics tracking causing delays, errors, and poor visibility across the supply chain.
SOLUTION:Engineered a comprehensive logistics platform with real-time tracking, route optimization, automated dispatch, and mobile driver apps.
Voice-Enabled AI Assistant
PROBLEM:Customer support teams overwhelmed with repetitive queries, impacting response times.
SOLUTION:Developed an AI assistant with voice interaction using LangChain for context management, ElevenLabs for TTS, and WebSocket for real-time communication.
How I Think About Systems
Architecture isn't about choosing tools — it's about designing boundaries, managing complexity, and building for change.
Scalable Architecture
Design systems that grow horizontally. Stateless services, distributed caching, and auto-scaling as first-class concerns.
Event-Driven Design
Decouple services through asynchronous messaging. SQS, SNS, and event buses for resilient, loosely-coupled systems.
Microservices Boundaries
Clear domain boundaries, independent deployability, and autonomous teams. Each service owns its data and lifecycle.
Cloud-Native Thinking
Infrastructure as code, container orchestration, serverless where appropriate. Cloud is the platform, not the afterthought.
Resilience & Performance
Circuit breakers, retry policies, graceful degradation. Observe everything — latency, errors, throughput, saturation.
AI Integration Strategy
Embed intelligence into real systems — not toy demos. RAG pipelines, agent workflows, and voice-enabled interfaces in production.
