Full Stack Developer | Systems & Software Architect

Self-Employed / Freelancer • Self-employed

Dec 2024 - Present • 1 yr 9 mos

Independent software engineer running MTLG Labs, a personal software lab focused on developer tools, systems engineering, and web platforms. My work spans open-source utilities, in-browser WebAssembly engines, and standalone client products. Key work and shipped engineering: • Developer Workbenches: Built MCP Studio (an Electron IDE for testing Model Context Protocol servers), DuckStudio Web (in-browser SQL workbench running DuckDB-Wasm and Apache Arrow), and SnapFrame.store (screenshot studio with Fastlane 4K export). • Browser Tools: Created APIScope, a Chromium DevTools extension that analyzes API network traffic, audits OWASP security headers, and exports TypeScript interfaces. • Systems & Storage Engines: Implemented Pebble-LSM (a Java 21 LSM-tree storage engine with WAL persistence and SSTables), Veloce Engine (a limit order book matching engine using the LMAX Disruptor ring buffer), and QueryLens (a PostgreSQL wire proxy that catches N+1 queries in flight). • Open-Source Tooling: Published over 40 packages across npm, PyPI, and GitHub. Built the bubble-io-cli suite for static analysis and localization, and contributed Windows cross-platform support to diskwatch. • Mobile & Mini Apps: Published native Android applications on Google Play (including Oneira) and built offline-first Telegram Mini Apps (such as RestPocket). • Client Solutions: Work with founders on technical architecture, payment setups (Stripe), and early-stage product MVPs.

EazyCode

Senior AI Product Engineer | Certified Bubble.io Developer

EazyCode • Full-time

Jan 2021 - Present • 5 yrs 8 mos

I build web applications and SaaS MVPs at EazyCode, leveraging Bubble.io and visual development tools (no-code/low-code platforms, AI builders, and workflow automation) alongside custom code and AI integrations for startups and international clients. What I do: • Architect scalable web applications in Bubble.io integrated with LLM APIs (OpenAI, Claude, Gemini) for AI assistants, automated data extraction, and dynamic workflows. • Design relational database schemas, user authentication, role-based access control (RBAC), and robust Bubble privacy rules. • Develop custom Bubble.io plugins (server-side actions, client elements) and API Connector integrations with JavaScript/Node.js whenever native features are insufficient. • Integrate third-party services including Stripe Connect, PayPal, webhooks, and external REST APIs. • Audit and fix database bottlenecks to keep page loads and workflow execution fast. • Work directly with founders from early wireframes through production launch.
