Enterprise Architecture · Contract & Fractional Engagements

Architecting resilient, cloud-native systems for B2B and B2C platforms at scale. I design event-driven Go microservices, AI/LLM orchestration pipelines, and high-throughput data architectures — available for contract, fractional, and advisory roles.

Agentic AI · LLM Fine-Tuning · RAG Architectures

Building production-grade AI systems that reason over codebases, generate intelligent reports, and orchestrate complex agentic workflows. I bring hands-on expertise in LLM fine-tuning, RAG pipeline design, and prompt management — delivering real business outcomes, not prototypes.

React · Node.js · Go · AWS · Contract Engagements

Full stack engineering built for scale. From React/Next.js frontends to Go microservices backends on AWS — I deliver production systems that handle millions of users. Available for part-time and contract roles where you need senior-level execution without full-time commitment.

Full Stack + AI · React · Node.js · Go · LLMs · AWS

One engineer who can take an AI product from idea to production — UI, API, infra, and the LLM layer in between. I build agentic pipelines, RAG systems, and OpenAI integrations and wrap them in real React/Next.js apps backed by Go and Node.js on AWS. Available for select engagements, without full-time overhead.

Golang · Microservices · gRPC · Event-Driven Backends

Production Go at scale. I design event-driven microservices, gRPC APIs, and high-throughput pipelines that stay fast under load — 48K events/sec with 12ms p99. If you need a Golang engineer who ships idiomatic, well-tested, observable services, that's what I do.

Next.js 14 · App Router · React Server Components · TypeScript

Modern React done right. I build Next.js App Router apps with server components, fast loads, and clean TypeScript — frontends that rank well, convert, and hold up at 2M+ concurrent users. Performance and SEO are baked in, not bolted on.

Serverless · ECS Fargate · Lambda · Infrastructure as Code

Cloud architecture that scales without surprises on the invoice. I design AWS systems — serverless and containerized — with the observability, IaC, and cost discipline to run them in production. From greenfield builds to taming infrastructure that's grown out of control.

Retrieval-Augmented Generation · Agentic Workflows · Vector Search

AI that actually grounds its answers. I build RAG pipelines and autonomous agents that reason over your data — retrieval, orchestration, evaluation, and guardrails — and ship them as real production systems, not demos. Built an agent reasoning over 10+ microservices at 94% accuracy.

Technical Leadership · Architecture · AI Strategy · Part-Time

Senior technical leadership without a full-time hire. I help founders set architecture direction, make the right build-vs-buy and AI-adoption calls, shape the roadmap, and level up the engineering team — on a fractional, part-time basis that fits an early-stage budget.

LLM Applications · Fine-Tuning · Prompt Engineering · Evaluation

Generative AI that earns its place in the product. I design LLM applications with the unglamorous parts handled — prompt management, evaluation, cost control, and fallbacks — so features stay reliable in production. From first prototype to a system you can trust with users.
