BunkerCoin — a blockchain over shortwave radio
Professional work · Open source
Core contributor to an open-source blockchain protocol that runs Alpenglow consensus over HF shortwave radio — from the Rust consensus node to the public API layer and the node infrastructure behind it.
Problem
Blockchains assume fast, reliable internet. Shortwave radio gives you 50–2400 bps, heavy packet loss, and ~300-byte packets — and consensus, block propagation, and a public explorer API all have to survive that.
Approach
Harden the Rust node against real radio conditions instead of simulated ones, build the RPC and API layer that exposes blocks, transactions, and live radio stats, and stand up the secured bastion-and-API infrastructure that connects live radio nodes to the public internet.
Notes
Top contributor to the core repo. The best bugs only appeared on real PACTOR modem hardware: corrupted radio frames triggering absurd allocations, restarts that silently wiped the chain, and a modem that froze without erroring — fixed with decode limits, deterministic padding, restart-safe finalization, and a link watchdog that self-heals the connection.

NDA-protected media and analytics platform
Professional work · Redacted due to NDA
A deliberately redacted case study covering custom DRM, real-time video, analytics infrastructure, and compliance automation.
Problem
The platform had to protect content, support low-latency media workflows, process analytics data reliably, and automate parts of compliance without turning the system into a black box.
Approach
Treat rights enforcement, streaming, analytics, and compliance as one interconnected product system, while keeping the public description focused on engineering shape rather than confidential implementation detail.
Notes
This public version stays intentionally high-level. The relevant point is the range of system problems solved, not the specific internal product details.

@Boostx AI-driven creator chatbot service
Professional work · Production
Product engineering for a chatbot service designed to strengthen how online content creators interact with their fans.
Problem
Creator communities need responsive fan interaction, payment flows, and conversational experiences that feel useful in production rather than impressive only in a demo.
Approach
Combine messaging integrations, monetization flows, and custom LLM deployment into a product that is operationally reliable and clear for both creators and fans.
Notes
The work covered the boundary between backend engineering and applied AI: deploying model-backed behavior, wiring product flows, and making the service practical to use.

@Vennie sales automation platform
Professional work · Production
Product work for an advanced AI-driven sales automation platform aimed at small and medium-sized enterprises.
Problem
A sales automation product needs model-backed workflows, secure account connectivity, outreach tooling, and internal prioritization systems that work beyond a demo environment.
Approach
Combine LLM-backed workflows, Gmail connectivity, payment flows, and lead-enrichment systems into a product that supports both user-facing automation and internal sales operations.
Notes
The work included lead and people enrichment, support-channel detection, deal pipeline tracking, task management, outreach workflows, and the integrations needed to make the platform practical in production.

Aluung
Side project · Live
A financial inclusion tool for informal savings groups, built to make contributions, records, and group visibility easier to manage.
Problem
Many community savings groups still rely on chat threads and handwritten records, which makes transparency and continuity difficult.
Approach
Start with the smallest workflow that helps a group stay organized, then expand only where the product reduces real friction.
Notes
Aluung is where product thinking matters most for me: practical software for people who need clarity more than complexity.

School timetable management
Side project · Live
A timetable system for schools that auto-generates conflict-free schedules with an in-browser constraint solver, then lets staff refine the result with drag-and-drop and export PDFs.
Problem
Building a school timetable by hand means juggling teacher availability, double periods, subject pairings, daily maxima, and avoid-days — and most schools still do it in spreadsheets.
Approach
Run the solver in the browser inside a Web Worker: MRV-ordered construction followed by time-budgeted simulated annealing over feasibility-preserving moves. The server, on the Cloudflare Workers free plan, only serves solver input and re-validates every hard constraint before persisting — the client is never trusted.
Notes
Results are seeded and reproducible, with live progress and cancel in the UI. When a lesson cannot be placed, it reports the specific constraint that blocked it instead of failing silently. Solver modules are pure TypeScript and fully unit-tested.
