Businesses hire me when they need someone who can build the product, own the infrastructure, and integrate AI where it creates real leverage end-to-end, without handoff gaps. I've delivered scalable web applications, cloud-native systems, automated CI/CD pipelines, and AI-powered workflows for startups moving fast and enterprises that can't afford downtime. Whether the challenge is a new SaaS build, a legacy modernization, a cloud cost problem, or automating a manual process with AI. I bring the development depth, DevOps discipline, and automation mindset to solve it. What clients consistently say: clear communication, no surprises on timelines, and solutions built to last. .NET Web API (with Angular / React / Vue.js) Enterprise-grade back-end with .NET Core and C#, delivered as MVC web applications or modern Blazor SPAs, all within the .NET ecosystem. For teams preferring a JavaScript front end, I pair .NET back-ends with Angular, React, or Vue.js. Ideal for corporate platforms, internal tools, ERP-style systems, and SaaS products that demand performance, maintainability, and long-term support. MERN Stack (MongoDB · Express · React · Node.js) JavaScript is end-to-end fast to build and easy to scale. My go-to for modern web apps, real-time features, and startup MVPs that need to move quickly without sacrificing quality. MEVN Stack (MongoDB · Express · Vue.js · Node.js) Clean, reactive front ends backed by a robust Node/Express API layer. Well-suited for dashboards, portals, and data-driven interfaces where a lightweight, approachable UI framework makes sense. MEAN Stack (MongoDB · Express · Angular · Node.js) TypeScript-first, strongly-typed, and enterprise-ready. Angular's structure makes this stack a natural fit for large teams, complex business logic, and long-lived applications. Across all stacks: RESTful APIs and GraphQL, SQL Server / PostgreSQL / MySQL / MongoDB for data, and microservices architecture where scale demands it. — Cloud & DevOps Engineering — AWS: EC2, Lambda, ECS, EKS, RDS, S3, CloudFront, IAM, VPC, Route 53, SQS, SNS, Secrets Manager, SSM Azure: App Service, AKS, Azure Functions, Azure DevOps, Cosmos DB, Blob Storage, Key Vault, Active Directory GCP: GKE, Cloud Run, Cloud Functions, Cloud SQL, Pub/Sub, Firebase, Artifact Registry Infrastructure as Code: Terraform, Pulumi, Atlantis Containerization: Docker, Kubernetes (EKS, GKE, ECS, Rancher) CI/CD Pipelines: GitHub Actions, GitLab CI, Jenkins, CircleCI, Bitbucket Pipelines Configuration Management: Ansible, Puppet Monitoring & Observability: Prometheus, Grafana, ELK Stack, Loki, Thanos, DataDog, New Relic Security & Secrets: HashiCorp Vault, AWS SSM, Azure Key Vault — Cloud & AI Automation — I integrate AI into products and workflows that save real time and create measurable value. LLM Integration: OpenAI (GPT-4o, o1), Anthropic Claude, Google Gemini embedded into applications via API for chat interfaces, document processing, code generation, and decision support. AI Workflow Automation: n8n, Zapier, Make (Integromat) building multi-step automations that connect your tools, eliminate manual handoffs, and run without human intervention. LangChain & RAG Systems: Retrieval-augmented generation pipelines that connect LLMs to your own data — internal knowledge bases, document Q&A, and intelligent search. AI Agents: Autonomous agents using LangChain, LlamaIndex, and AutoGen that can perform research, write reports, and execute multi-step tasks. Vector Databases: Pinecone, Weaviate, Chroma for fast semantic search and context retrieval in AI applications. AI-Powered APIs: Back-end services that expose AI capabilities to your front end or third-party systems. — What I can build for you — ✦ Enterprise web apps and SaaS platforms (.NET MVC, Blazor, MERN, MEVN, MEAN) ✦ Cloud infrastructure on AWS, Azure, or GCP setup, migration, cost optimization ✦ CI/CD pipelines and end-to-end DevOps implementation ✦ AI chatbots, document assistants, and LLM-powered features in your product ✦ Automated workflows that eliminate manual, repetitive processes ✦ API design, third-party integrations, and microservices architecture ✦ Performance tuning, scalability improvements, and system modernization I scope carefully, communicate proactively, and deliver what I commit to. If something's going to take longer than expected, you'll hear it from me first.
