I build and run Production Infrastructure on AWS, GCP, Azure and on-prem. Most of my work the last few years has been Kubernetes (EKS, GKE, AKS, and bare metal RKE2 with Rancher) and getting that infrastructure through compliance audits: HIPAA, SOC 2, PCI DSS, NIST 800-53. 10+ years in DevOps. Top Rated Plus, 100% Job Success. 𝙎𝙤𝙢𝙚 𝙧𝙚𝙘𝙚𝙣𝙩 𝙥𝙧𝙤𝙟𝙚𝙘𝙩𝙨 𝙩𝙤 𝙜𝙞𝙫𝙚 𝙮𝙤𝙪 𝙖𝙣 𝙞𝙙𝙚𝙖 𝙤𝙛 𝙬𝙝𝙖𝙩 𝙄 𝙖𝙘𝙩𝙪𝙖𝙡𝙡𝙮 𝙙𝙤: Built an on-prem RKE2 cluster from scratch for a company preparing for SOC 2 and HIPAA. Rancher for management, Cilium with WireGuard for encrypted pod traffic, GPU nodes for their ML workloads, Longhorn for storage, Velero for backups, ArgoCD for deployments. Also enforced SSO through Entra ID on every cluster and SSH access point because their auditors required it. Took a healthcare data platform through HIPAA hardening on AWS. ECS Fargate, Aurora PostgreSQL, private subnets, TLS everywhere, proper secrets handling. Phase one was making it work, phase two was making it pass an audit. Different skill sets, I do both. Modernized AWS infrastructure for a holding group running four brands. Moved everything to ECS Fargate and Aurora Multi-AZ, set up blue-green deployments, CloudFront in front. Midway through we found a security breach in their GitHub org and I handled the full remediation across every repo. Fixed a production Aurora MySQL performance problem that had their app timing out during peak hours. Root cause was tmp table spill to disk. Tuned it, added a reader, no downtime. I also do a lot of unglamorous work that keeps things running: CI/CD pipelines (GitHub Actions, GitLab CI, ArgoCD), Terraform for everything, monitoring with Prometheus and Grafana, cost cleanup, VPN and networking issues, database migrations. Industries I know well: Healthcare (HIPAA is second nature at this point), Fintech and Payments (PCI DSS), and B2B SaaS. 𝙒𝙝𝙖𝙩 𝙮𝙤𝙪 𝙜𝙚𝙩 𝙬𝙤𝙧𝙠𝙞𝙣𝙜 𝙬𝙞𝙩𝙝 𝙢𝙚: Infrastructure that is written down in code, documented, and reproducible.

I will give you an honest read on scope and effort before you spend anything.

I build the entire ecosystem from API to Insight and eliminate the need to hire separate backend and data engineers. With 8+ years of deep JVM, Python, and modern data engineering experience, I help companies ranging from agile startups to enterprise giants like JPMorgan Chase launch scalable APIs and high-performance data systems at startup velocity delivering production-ready platforms with zero hand-holding. 𝗛𝗼𝘄 𝗜 𝗵𝗲𝗹𝗽 𝗕𝘂𝘀𝘀𝗶𝗻𝗲𝘀𝘀𝗲𝘀 𝘁𝗼 𝗧𝗿𝗮𝗻𝘀𝗳𝗼𝗿𝗺 𝗗𝗮𝘁𝗮 𝗶𝗻𝘁𝗼 𝗜𝗻𝘀𝗶𝗴𝗵𝘁𝘀: • Enterprise Backend Architecture: Designing highly available microservices with Java, Kotlin, and Spring Boot built for millions of daily transactional API requests. • Modern Data Engineering: Implementing production-grade Snowflake + dbt (SQL/Python) stacks and high-throughput streaming/batch pipelines with PySpark and Apache Beam. • Cloud & Infrastructure Automation: Multi-cloud engineering on AWS, Azure and GCP, executing complex zero-downtime data migrations and containerized deployments via Terraform. • Data Warehouses: I design and manage data warehouses that provide a centralized repository for your data, facilitating efficient data analysis and reporting. I have led data and backend infrastructure engineering at JPMorgan Chase, Ford Motor Company, Global Atlantic Financial, and JetBlue Airways, delivering repeatable, cost-efficient platforms with zero hand-holding. 🌟 Some of What I have Shipped: • Ford Motor Company: Slashed a 6-hour legacy Hadoop batch job to under 10 minutes (97%+ runtime improvement). • JPMorgan Chase: Built core credit card banking microservices handling millions of daily transactions with zero downtime. • JetBlue Airways: Designed high-throughput observability streaming pipelines serving thousands of daily travelers. 🛠️ Key Tools & Technologies • Languages: Python, Java (8-17), Kotlin, SQL • Data & ETL: Snowflake, dbt, Apache Spark (PySpark), Apache Beam, GCP Dataflow, AWS Glue, Apache Airflow, Kafka • Backend & Web: Spring Boot, Spring MVC, Microservices, RESTful APIs, GraphQL, Apigee, Swagger/OpenAPI • Cloud & DevOps: GCP (BigQuery, Pub/Sub, Cloud Run, GKE), AWS (S3, Lambda, Redshift, EKS), Terraform, Kubernetes, Docker, GitHub Actions • Databases & Observability: PostgreSQL, SQL Server, MongoDB, Redis, Grafana, Prometheus, Splunk 🎯 You should consider me immediately if your team needs: • The "Two-Engineer" Solution: You need someone who can build the backend transactional APIs and architect the heavy data processing pipelines without hiring two separate people. • Modern Stack Migration: You are moving away from legacy data infrastructure and need an autonomous expert to design a modern Snowflake + dbt ecosystem. • Critical Performance Optimization: Your current data processes or backend services are sluggish, breaking constantly, costing too much on AWS/GCP, or failing to scale. • Autonomous Delivery: You do not have time to micro-manage. You need a veteran engineer who can read the requirements, write clean code, handle deployments, and deliver independently. Based in New Jersey, USA.

𝗪𝗵𝘆 𝗵𝗶𝗿𝗲 𝗺𝗼𝗿𝗲 𝘄𝗵𝗲𝗻 𝗔𝗜 𝗰𝗮𝗻 𝗱𝗼 𝗶𝘁 𝗯𝗲𝘁𝘁𝗲𝗿?🤖 I help businesses stop bleeding time and money on repetitive work. Through AI automation, I streamline operations, cut unnecessary costs, and turn raw data into insights that actually drive decisions. What I build 🛠️ I design and deploy AI agents that handle the heavy lifting across support, finance, HR, compliance, and supply chain operations. Using LangChain, LangGraph, and n8n, I deliver real systems that work in production, not just in demos. When one agent isn't enough, I engineer full multi-agent environments where AI teams collaborate to run complex business operations with minimal human involvement 🧠 I also build RAG pipelines that plug your internal knowledge directly into LLMs, so your AI understands your business from the inside out ⚡ Need content generation, market research automation, or smart conversational bots? I build those too, opening new revenue channels without growing your headcount 📈 Everything I deliver is production-grade. Python, FastAPI, Django, Docker, Kubernetes, deployed on AWS, Azure, or GCP with solid CI/CD practices 🚀 Recent work I'm proud of 💼 A marketing agency got fully automated campaign pipelines. A crypto platform got a real-time AI trading co-pilot. An IT firm got autonomous network troubleshooting agents. A healthcare provider got patient conversations turned into structured EMR notes. A construction company got clean data extracted from complex permit PDFs. ✅ Why clients trust me 🤝 I stay invested long after delivery. What matters to me is the time you save, the costs you cut, and the results you see. I collaborate closely with LangChain's core team and stay ahead of where AI is moving, so what I build stays relevant. If you're ready to put AI to real use in your business, let's talk 💬
