Monitoring, alerting, and security baked in from day one to support 24/7 operations.

AI & Data

From API‑first integration (ChatGPT, Gemini, Claude) through RAG and fine‑tuning to custom training – I work across the full stack so you ship at the right level for your product and budget.

AI Engineering
API & orchestration
OpenAI, Anthropic, Gemini, Claude APIs · prompt design and agents (LangChain, LangGraph) · when to use paid APIs vs open weights (Llama, Mistral) · production rollout and cost control
Models & adaptation
Paid APIs vs open‑weight models · fine‑tuning (API or LoRA/QLoRA) · embeddings and vector stores · RAG pipelines, chunking, retrieval evals · self‑hosted vs inference APIs (Together, Groq)
Data & MLOps
PostgreSQL, Redis, vector DBs · embedding and indexing pipelines · prompt and model evaluation · tracing, observability · training pipelines and infra when custom models are needed

I help choose and build the right stack: API‑only, RAG on your data, or custom training – so you ship measurable impact to production, not research demos.

PROCESS

Transparent delivery from discovery to operations.

A senior engineer leads every stage and keeps scope, timeline, and risk clearly visible.

  1. 01

    Discovery & scoping

    Understand your business goals, constraints, and existing systems. Produce a high‑level solution outline and effort estimate.

  2. 02

    Architecture & planning

    Design system architecture, data flows, and release strategy. Prioritize scope into milestones with clear deliverables.

  3. 03

    Implementation & QA

    Iterative development with code reviews, automated tests, and regular demos. Security and performance considered from the start.

  4. 04

    Launch & operate

    Roll-out, monitoring, and on-call support. I can operate the platform for you or hand it over with training and documentation.
