Optimized for performance, battery usage, and real-world network conditions.

Cosmos

Cosmos SDK, Tendermint / CometBFT, IBC, custom modules

Solana

Rust, Anchor Framework, SPL tokens, on‑chain programs

Web3

ethers.js, web3.js, wallet adapters, indexers

Close collaboration with you and your stakeholders to design tokenomics, governance, and operational processes.

Cloud

AWS, GCP, Azure, containerized workloads

Orchestration

Docker, Kubernetes, Helm, managed PaaS

Ops

GitHub Actions, GitLab CI, Prometheus, Grafana, ELK stacks

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

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.
