About

I'm a backend & systems engineer with ~5 years building the parts of software that have to be correct: data pipelines, APIs, payment-adjacent systems, and the infrastructure under them.

Lately my work centres on AI-integrated platforms (real-time assistants, LLM/STT/TTS and vision pipelines, and multi-model orchestration) on top of solid backend and distributed systems across fintech and SaaS. I like problems where reliability, consistency, and latency all matter at once.

I work mostly in Python and C#, with FastAPI, ASP.NET Core, PostgreSQL/TimescaleDB, Redis, Docker, and Kubernetes as my default toolkit, and I explore Bitcoin and the Lightning Network on the side.

AI-Integrated Platforms

01

Production systems built around LLMs and multimodal AI, not demos. Real-time assistants, multi-model orchestration, and prompt architecture tuned for quality, cost, and latency.

›LLM orchestration (OpenAI, Claude) · prompt engineering
›Real-time AI over WebSockets · STT / TTS · vision models
›Multi-model coordination on GPU servers
›NLP · ML fine-tuning · AI agents

Backend & Distributed Systems

02

Services built to stay correct under load: typed APIs, microservices, queues, and clean boundaries, deployed and orchestrated for scale.

›Python (FastAPI, Django) · C# (ASP.NET Core)
›REST · GraphQL · WebSockets · microservices
›PostgreSQL · TimescaleDB · Redis · SQLAlchemy
›Docker · Kubernetes · CI/CD

Fintech & SaaS

03

Systems where money and multi-tenancy are first-class: billing, payments, enterprise access, and auditable, reliable data.

›Multi-tenant SaaS · RBAC · SSO · audit logging
›Stripe billing: subscriptions & webhooks
›Backtesting engines · time-series at scale
›Secure financial data pipelines

Bitcoin & Lightning (exploring)

04

Hands-on protocol work through Bitshala's Programming Bitcoin (S2) and the boss-2026 Lightning challenges: coursework and challenges, but real depth.

›Finite fields · ECC · Script · SegWit
›Lightning routing · onion building · coin selection
›Signet wallets · a from-scratch Bitcoin wallet
›Networking & SPV · bloom filters
