Hey, I'm Aleksandr

Full-stack engineer in Helsinki. 15+ years building products, mostly with TypeScript, Node.js, React, and AWS.

I like taking ideas from "not sure this will work" to running in production. Most of my work sits at the intersection of new tech and actual business problems.

What I'm working on

arxiv-search — semantic search across 1M+ arXiv papers, runs entirely in your browser. Zero infrastructure costs. This one got some traction.

Kaban — terminal Kanban board built for AI code agents. Has an MCP server so Claude Code, Cursor, etc. can manage their own task boards.

us-legal-tools — TypeScript SDKs for US legal APIs (eCFR, Federal Register, CourtListener, GovInfo, DOL). Auto-generated from OpenAPI specs, monorepo with Turborepo.

eyecite-js — TypeScript port of Free Law Project's eyecite library for extracting legal citations from text.

Older projects I still care about

Caesar — open-source zero-knowledge password manager for teams. AES-256 + RSA-4096, all encryption client-side, the server never sees plaintext. I designed the crypto architecture and built it from scratch.

bitnami-pgvector-search — multi-arch Docker image combining PostgreSQL, pgvector, and pg_search. Gets auto-built and tested via GitHub Actions.

Background

Co-founded 4xxi (product dev for US/UK clients) and Denovo (AI/ML consulting, fractional CTO). Built products across legal tech, fintech, edtech. Before that — mobile dev, Android, startups in various states of aliveness.

These days I'm especially interested in RAG pipelines, vector search, MCP servers, local-first apps, and making AI tools that actually work in production rather than just in demos.
