Building an AI agent or RAG demo is easy. Making it reliable, secure, observable, and financially predictable in production is where most projects fail.
I help SaaS and enterprise teams design, build, and rescue production AI systems on AWS.
Expert-Vetted Top 1% AI Consultant on Upwork
- 100% Job Success
- $80K+ earned
- 2,700+ hours delivered
- 41 Upwork engagements
- 9+ years of production engineering experience
- Three AWS Professional certifications in Generative AI, Solutions Architecture, and DevOps
✓ CLIENTS USUALLY CONTACT ME WHEN
- An AI agent works in a demo but fails with real users, tools, permissions, or business data
- A RAG system retrieves the wrong information, produces weak citations, or becomes unreliable at scale
- An AI proof of concept needs to become a secure and maintainable production product
- Claude, OpenAI, or Amazon Bedrock must be connected to real business workflows
- AWS infrastructure has reliability, security, scalability, or cost problems
- A development team needs senior technical ownership rather than another task-based developer
- An existing implementation needs architecture review, debugging, or production rescue
→ WHAT I BUILD
PRODUCTION AI AGENTS
- AI agents and agentic workflows
- Claude, OpenAI, and Amazon Bedrock integrations
- Tool calling, MCP servers, and external system integrations
- Human approval and escalation workflows
- Agent memory, state management, and context handling
- Evaluations, guardrails, tracing, and failure recovery
- Multi-agent orchestration where it is genuinely justified
PRODUCTION RAG SYSTEMS
- Document ingestion and processing pipelines
- Vector search and hybrid retrieval
- Metadata filtering, reranking, and access control
- Reliable citations and source attribution
- Retrieval and response evaluations
- Enterprise knowledge assistants
- Multi-tenant RAG architecture
- OpenSearch and vector database integrations
AWS ARCHITECTURE AND PLATFORM ENGINEERING
- Serverless and event-driven systems
- AWS Lambda, API Gateway, DynamoDB, SQS, EventBridge, and Step Functions
- Terraform, AWS CDK, CloudFormation, and infrastructure automation
- IAM, tenant isolation, security boundaries, and least-privilege access
- Monitoring, observability, incident recovery, and architecture reviews
- AWS cost optimization, performance improvement, and cloud migrations
★ SELECTED PRODUCTION EXPERIENCE
- Worked on a high-volume ordering platform processing millions of transactions per month with strict uptime, performance, and recovery requirements
- Delivered a 686-hour AWS engagement involving Cognito, Lambda, SQS, backend services, and production infrastructure, followed by a five-star client review
- Improved production systems across SaaS, healthcare, fintech, cybersecurity, and streaming
- Owned delivery across architecture, critical implementation, deployment, security, observability, and engineering handoff
I work hands-on across Python, Node.js, TypeScript, APIs, distributed systems, cloud infrastructure, and modern AI frameworks such as LangGraph and LangChain.
→ HOW I WORK
I do not begin by selecting an AI framework.
I begin with:
- The business workflow
- The users and permission boundaries
- The available data
- The expected result
- The failure modes
- The security requirements
- The operating cost
- The team's ability to maintain the system
From there, I design the smallest architecture that can safely achieve the required outcome.
I will also tell you when:
- An AI agent should be a deterministic workflow
- RAG is unnecessary for the use case
- A managed service is creating avoidable cost or lock-in
- The proposed architecture is too complex
- A feature is likely to waste more money than it creates in value
- A prototype is not yet ready for production use
Avoiding the wrong architecture often saves more time and money than writing additional code later.
You can expect clear communication, visible progress, documented decisions, honest risk analysis, and production-focused validation. I stay involved through production readiness and engineering handoff, not only prototype delivery.
I am a strong fit when AI must interact with real users, business data, external tools, and production infrastructure.
Send me your architecture, requirements, repository context, or production problem.
I will review the context, identify the highest-risk area, and recommend the most practical starting point.

I build infrastructure that stays up when it matters. Government platforms for 2M+ citizens, banking systems for 1M+ users, and AI rendering stacks on GPU Kubernetes clusters. Shipped on time, documented for the team that inherits it.
5+ years owning the full stack: physical hardware, hypervisors, Kubernetes, service mesh, cloud networking, CI/CD, observability, and GPU AI workloads. Across government, fintech, SaaS, and deep-tech startups.
Government Scale — OpenG2P Ethiopia, 3 Ministries
Leading platform engineering for Ethiopia's national OpenG2P welfare system across ATI, MoWSA, and EDRMC. Serving 2M+ beneficiaries on RKE2 with Rancher, Istio mTLS, Keycloak SSO, WireGuard site-to-site VPN, XCP-ng hypervisor with Hardware RAID 1+0, and a full Prometheus + Grafana + Alertmanager + Loki observability stack. Currently executing a large-scale ODK to OpenG2P data migration with schema mapping, validation pipelines, audit trails, and phased rollback.
AWS Serverless Architecture — WeTruck
Architect and operator of WeTruck's serverless logistics platform. CloudFront to ALB to WAF (deny-by-default with Telebirr payment gateway IP whitelisting) to Lambda (FastAPI via Mangum). Fully Terraformed infrastructure. GitHub Actions with OIDC federation (zero long-lived credentials), RDS PostgreSQL, DynamoDB for JWT token store, SQS with dead-letter queue, Secrets Manager, AWS Amplify for three Next.js frontends (back-office, transporter, shipper), and Route 53 private/public DNS. I own production incidents end-to-end and authored the full deployment runbook and troubleshooting playbook.
AWS in daily use: Lambda, EC2, EKS, CloudFront, ALB, WAF, RDS, DynamoDB, SQS, Secrets Manager, Amplify, ECR, Route 53, IAM OIDC, VPC (private subnets, NAT Gateway, VPC endpoints), CloudWatch, ACM.
MPLS and AI Rendering Infrastructure — MetaPlux (Tech Lead)
Tech Lead on a distributed GPU-aware AI rendering platform. MPLS networks for deterministic, low-latency routing across distributed rendering nodes with label-switched paths and traffic engineering for QoS-sensitive GPU workload traffic. BGP and OSPF routing across hybrid environments connecting on-premises GPU clusters to cloud egress points. WireGuard VPN tunnels for secure, auditable connectivity. Multi-cloud strategy across AWS and Azure for rendering workload distribution. Platform architecture for GPU-aware Kubernetes scheduling and job orchestration.
This role sits at the intersection of deep networking and modern cloud infrastructure, the combination most DevOps engineers don't have.
AI and GPU Infrastructure — Exponent.ch (Switzerland)
Provisioned and managed NVIDIA GPU-enabled RKE2 clusters running AI and automation workloads: n8n, Langfuse LLM observability, LibreChat, and ClickHouse analytics. Standardized Helm deployments across 5+ environments using shared-stacks architecture. Integrated Teleport for zero-trust cluster access, automated secrets via Lade and 1Password. Prometheus + Grafana + Mimir observability with 99.9% metric coverage, 60% MTTR reduction, and 3 critical outages prevented through proactive alerting.
Banking Infrastructure — 6 Ethiopian Banks, 1M+ Users
Delivered high-availability mobile banking and USSD platforms for Siinqee Bank, Hijra Bank, Wegagen Bank, and others with 99.95% uptime across 1M+ users. Designed MPLS network architecture for multi-branch WAN connectivity with QoS for transaction data. Built Jenkins CI/CD for Maven Java apps (4 hours to 15 minutes). ELK processing 10TB+ daily logs. Proxmox and AWS hybrid cloud with ~35% cost reduction.

Databases: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, DynamoDB
Backend: Python (FastAPI), Bash, Node.js
How I work
I overcommunicate early, give realistic timelines, and ship verified, not "it should work." I treat testing as the real deliverable, not a checkbox. If something is out of scope or a bad idea, I'll tell you before you spend money on it.
Message me if you need:
- AWS or Kubernetes infrastructure built or fixed
- CI/CD pipelines developers actually trust
- GPU and AI infrastructure with inference pipelines and observability
- Migration from cloud to cloud, or on-prem to production cloud
- MPLS, BGP, or complex network architecture across hybrid environments
- Observability that catches problems before users do
