You will get AWS Lambda Micro-Service API + Gateway + MCP Middleware | Secure REST
Top Rated
Top Rated
Project details
You will get a production-grade REST micro-service built on AWS Lambda + API Gateway, delivered entirely as Terraform Infrastructure-as-Code and wrapped with MCP middleware so future GenAI or RAG pipelines can tap clean, well-scoped context.
I design lean, cold-start-friendly Lambdas (Python 3.11 by default, Node 20 or Go 1.x on request) with JWT / Cognito / API-Key auth, VPC links, WAF rate-limits, and encrypted secrets. Each tier ships with a GitHub Actions pipeline that auto-deploys to dev → stage → prod, plus CloudWatch logs and optional X-Ray tracing.
Past builds for e-commerce, IoT, and SaaS clients handle 5 M+ calls/month at <200 ms P95 while costing under $0.001 per request. Whether you need a quick proof-of-concept endpoint or a full enterprise API with SSO, observability, and autoscaling, this project gives you the fastest path to a secure, serverless backend—backed by runbooks, diagrams, and after-launch support.

Optimize MERN Agentic Platform for High-Scale File Uploads & Latency Reduction in Agent Voice Calls
I worked with Muhammad and his team on a MERN Agentic Platform project, and they exceeded our expectations. They not only fixed all our issues but also guided our team on resolving other challenges. They are excellent SaaS architects and truly understand how to build and scale SaaS products.

Spark Architect Wanted to Optimize 250TB Data Pipeline on AWS EMR + Glue + Redshift
Mudassir did an outstanding job optimizing our data pipeline. From day one, he demonstrated deep expertise in Spark, AWS EMR, Glue, and Redshift. Not only did he improve the performance and scalability, but he also provided valuable architectural insights and best practices that will benefit our team long-term.
Highly recommended for any team looking for a senior data engineer who can not only solve complex problems but also empower others in the process.

Fractional CTO/AWS consultant for Large Web Scraping Platform | System Design & Architecture
We brought in Cognilium as a Fractional CTO and AWS consultant to help us architect a large-scale web scraping platform—and they exceeded expectations. Their team provided us with a detailed, scalable system blueprint tailored to our use case, covering everything from distributed architecture and fault tolerance to cost-efficient AWS service selection.
They didn’t just consult—they acted as strategic advisors, helping us make critical design decisions and ensuring our internal team was set up for success. Thanks to their guidance, we were able to confidently build the platform in-house using a future-proof architecture.
Highly recommend Cognilium for any team seeking expert-level consulting on scalable AWS infrastructure and scraping system design.

GenAI Consultant - Automotive Parts Manufacturing IT Transformation
I can’t recommend Cognilium’s engineer highly enough. From day one he felt like an extension of our in-house team—always online when we needed him, answering questions within minutes, and proactively surfacing risks before they became blockers.
His grasp of generative-AI workflows was outstanding: he designed and implemented a truly scalable RAG pipeline that now powers real-time parts-search and knowledge retrieval across millions of records. Just as impressive, he re-architected our ERP workflow automation, untangling legacy processes and delivering a clean, modular design our own engineers can maintain.
Deliverables were shipped ahead of schedule, documentation was clear, and every sprint review ended with our stakeholders saying, “That’s exactly what we needed.” If you’re looking for a professional who can both code and collaborate—especially in manufacturing or automotive contexts—hire Cognilium without hesitation. Five stars all around.

🤝 How I Work
I scope before I build. Every project starts with a written architecture plan and acceptance criteria — you know exactly what you're getting before the first commit. Change requests go through milestones, not surprises.
• Weekly demos and async daily updates
• I respond within 4 hours
• POCs ship in under 2 weeks
• Full documentation and team handover — your team operates the system independently after I leave
Every system includes self-healing when APIs fail, automatic quality checks before outputs reach your users, and monitoring dashboards so you see exactly what's happening — not just hope it works.
I don't disappear after launch. Active clients right now: a $3,200/week AI co-pilot for K-12 education (repeat engagement through multiple phases) and a distributed scraping platform with a 5.0 rating across $56K in contracts (5 phases delivered over months). I build long-term — not hit-and-run.
🛠️ What I Build
AI Agent & Multi-Agent Systems
Supervisor routing, parallel execution, smart routing that cuts LLM costs by 75%, guardrails that block unsafe requests in real time. Google ADK, AWS Bedrock AgentCore, LangGraph, LangChain, CrewAI. From single agents to 23-agent orchestrated pipelines.
RAG & Knowledge Systems
Hybrid retrieval (dense + BM25 + Reciprocal Rank Fusion), GraphRAG with Neo4j, Vertex AI Search. Citations, audit trails, anti-hallucination grounding checks. LLM-as-Judge scoring validates every output before it reaches your users.
