Every project, in one table.

Engineering Document Search — Case study

Semantic and full-text search over an engineering-documentation archive of ~4.1k PDF, DOCX, XLSX and RTF files: a custom inverted index plus FAISS on sentence-transformers, behind a FastAPI service. No LLM generation.

Switchyard — Case study

A gateway in Go, standard library only, that sits in front of LLM inference servers: it never sends a replica more than it can run, refuses work it cannot serve in time with a retry time instead of a timeout, and retries a failed request on another replica only while the client has seen nothing - measured on a real GPU against a plain load balancer.

Proofbench — Case study

An evaluation platform for an LLM agent that moves money: deterministic graders read what the agent actually did, an LLM judge is used only for prose and is itself measured against a blind panel, recorded runs re-grade in seconds without a GPU, and a CI gate fails when grading quietly gets weaker.

Ledgerline — Case study

A payments platform where money is never created, lost or moved twice — a double-entry ledger on an event log, card payments and payouts as sagas, an outbox into Kafka, in-line fraud scoring, ClickHouse analytics, a gRPC merchants' API, and OpenTelemetry tracing, all proven by breaking it on purpose.

Depotwin — Case study

A live 3D digital twin of 240 simulated vehicles in Moscow — a Go and NATS JetStream pipeline into TimescaleDB, failure models that warn of breakdowns days ahead, a local-LLM copilot over read-only queries, and an offline-first driver app.

Clearhire — Case study

An AI recruiting platform that checks CVs against each requirement of a vacancy and shows the CV line behind every verdict — blind screening, a local LLM that must cite its sources, and an audit log anchored on a blockchain.

Lumen Search — Case study

Hybrid document search with citations over PDF, Word, Excel and scanned pages, in English and Russian — BM25 plus multilingual embeddings in FAISS, OCR and a FastAPI service.

Pulseboard — Case study

Self-hosted HTTP uptime monitoring with automatic incidents, SLO error budgets, a public status page and Prometheus metrics — all in one container.

DeployLedger — Case study

A self-hosted release-operations control plane: it ingests deployment events, computes DORA metrics and helps decide whether the next release is safe to ship.

Gatehouse — Case study

A self-hosted access request and approval control plane: narrowly scoped, short-lived access, with every decision recorded in a verifiable audit chain.

Webhook Workbench — Case study

A private, self-hosted workbench to capture, inspect, verify and safely replay webhooks — one dependency-free Go binary with the UI built in.

Stockroom Ledger

Transactional inventory operations with audited cycle counts, idempotent writes, and optimistic concurrency.

LeaseQueue

Durable background jobs with atomic leases, retries, idempotency, and dead-letter recovery.

Access Verdict

Explainable authorization policy workbench with deny-first evaluation, decision traces, and executable scenarios.

Smart Platform

Bilingual (EN/AR) Next.js marketing site for Kingdom Vision Equipment Rental, a heavy and light equipment rental company in Riyadh, Saudi Arabia.

Retry Lab

An interactive simulator for comparing retry, backoff, and jitter strategies.

Incident Canvas

Local-first incident postmortem workspace with a searchable archive, response metrics, and portable reports.

ToggleBench

Deterministic feature-flag targeting and rollout workbench with explainable decisions.

Repo Vitals

Transparent GitHub portfolio health check with shareable Markdown and JSON evidence reports.

Schema Sentry

Detect unsafe SQL migrations and scan only changed files in pull-request CI.

OpenAPI Impact

Detect breaking changes between OpenAPI specifications in local development and CI.

Git Hotspots

Rank high-risk files from Git history and track risk-score changes against a baseline.

SLO Forge

SLO-as-code compiler for Prometheus burn-rate alerts, Prometheus Operator resources, Grafana dashboards, and reviewable error budgets.

Platform Blueprint

GitOps reference platform with Flux, Flagger canaries, Kubernetes policy, observability, and Terraform EKS.

OKKP Operations Platform — Case study

An internal quality-control web system for a network of 9 vehicle depots. I designed the architecture and API and wrote most of the code: violations and fines, employees, a document archive and Excel export.

MyGPT

Readable character-level transformer with reproducible training, safe checkpoints, and an interactive causal-attention explorer.

Sehati Client

Front-end for Sehati, a clinic management system: React + TypeScript single-page app with Tailwind CSS and dashboard, patients, appointments, doctors and settings pages (UI prototype with mock data).

File Finder MCP

Bounded, ranked local file discovery for Model Context Protocol clients.

Micrograd+

Small autograd engine with computation-graph visualization and optimizers, built to learn neural networks from first principles.
