Rust UDP fan-out relay with per-packet throttling and physics-consistent lap replay.

• Rate limits are enforced per destination AND per packet id, with the timestamp buckets held as an Arc<Vec<AtomicU64>> specifically so they survive a destination-cache rebuild — otherwise editing one row would reset every throttle and let a burst through.
• The replay engine re-times a recorded lap with a closed-form solution that never touches world position or lap distance, reshaping the speed-versus-distance profile by a per-segment straightness weight and rewriting every kinematic field by the matching power of the local speed factor.

Async Python engine that prices crypto arbitrage after fees, slippage and transfer cost.

• The cost model never assumes a top-of-book fill: it walks order-book levels to produce a VWAP and a signed slippage figure, and clamps net profit to zero or below whenever the book cannot transact the requested size — so an untransactable edge can never be recorded as real money.
• Six independent circuit breakers — consecutive losses, a daily realised-loss cap, a volatility spike, error rate, round-trip latency and a kill-switch file — each engage by writing a halt file, so resuming requires a human to delete it rather than a timer expiring.

Cross-platform download accelerator: parallel HTTP range segments, resume, MV3 extension.

• It refuses to trust HEAD — after reading Content-Length and Accept-Ranges it sends a probe GET with Range: bytes=0-0 and only splits the file on a real 206, catching servers that advertise range support and lie about it.
• The localhost server parses the Host header, IPv6 brackets included, and returns 403 for anything non-loopback to block DNS-rebinding attacks, with CORS separately narrowed by regex to extension origins only.

Crypto-wagered esports platform with OCR match verification and Solana escrow.

• Built the screenshot verification pipeline: a 2× canvas upscale, contrast stretch, luminance-weighted greyscale and binary threshold ahead of Tesseract with a restricted whitelist, then username matching, a ±20 score tolerance and K/D/A regex returning a structured confidence verdict.
• Built the real-time 8-ball layer over socket.io — ball positions, cue drag, stick angle and spin — with pause-and-resume on disconnect against a deadline. The single-player physics underneath is a licensed CreateJS pool template; the sync, wagering and payout layers are the original work.

Islamic AI companion app: RAG over Quran embeddings, shipped to iOS and Android.

• Owned the iOS release track through App Store review remediation — app config, OAuth, the notification service, the auth bootstrap provider and native subscriptions. The RAG backend is a teammate's work.
• The client computes prayer times and qibla bearing on-device with adhan rather than round-tripping a server, and the app is localised into four locales including right-to-left Arabic and Urdu.

AI DevOps agent that scans repos, builds a manifest, and opens PRs with infra config.

• The scanner fingerprints polyglot services from marker files across eight ecosystems and detects Kubernetes manifests by regex-matching the YAML kind line rather than by filename, deduplicating candidates shortest-path-first so a stray Dockerfile is never promoted to its own service.
• Scanning is budget-bounded so a huge monorepo cannot blow up cost — 32 KB per key file, a 1.5 MB total read budget and an 800-call ceiling on the remote path, which sets a truncated flag instead of failing.

Full-stack PC retail commerce: Supabase, Razorpay webhooks, a configurator and rentals.

• The public post-checkout page is protected by a truncated base64url HMAC-SHA256 capability token verified with timingSafeEqual — no server-side token storage — and the module throws at startup if the auth secret is unset in production.
• The Razorpay webhook is the server-side source of truth: it verifies the signature over the raw body, resolves the order idempotently, and deliberately returns 200 on internal errors so Razorpay does not retry forever.

News platform with deterministic SEO rewriting and a balanced revenue-share ledger.

• A cyrb53 hash of the article slug seeds a mulberry32 PRNG, so the same story rewrites identically on every rebuild instead of thrashing caches and crawlers, with substitution skipping quoted spans, numbers, proper nouns, acronyms and URLs.
• Revenue share is double-entry in integer paise with largest-remainder apportionment so shares sum to the pool exactly and the platform line negates the distributed total, guarded by a balance invariant; authorisation lives in 29 row-level-security policies and the ledger is append-only by simply granting no UPDATE or DELETE.

WordPress/WooCommerce operations portal — Stripe Connect payouts, brackets and live event schedules.

• Stripe Connect carries the whole money path: transaction tracking, dispute handling, and winner payouts that settle automatically off a finished bracket or are released by hand when a result is contested.
• WooCommerce Core is extended rather than themed around — bracket, schedule and transaction state live in custom MySQL tables instead of a key-value meta layout that could not be queried, WP-CLI drives the bulk operations, and Action Scheduler runs the recurring settlement jobs in place of wp-cron.

Nightlife and social-experience platform — venue discovery, event listings, ride requests and ticketing.

• Built the event ticketing system end to end on PHP/Yii: purchase with promo-code support, a barcode generated at the moment of purchase, and on-site barcode scanning for attendee check-in at the venue door.
• Worked the venue and events feed in the same backend — venue profiles, event listings and payment processing — behind an Angular front-end.

Property-management platform — in-document annotation and high-traffic front-end performance work.

• Integrated PDFTron annotation and document customisation directly into the platform, so leases and inspection reports are marked up in place rather than exported, edited elsewhere and re-uploaded — the step that carried the manual processing time.
• Optimised front-end rendering across the highest-traffic modules and cut page load times, alongside the API-side eager caching that took average response time from 1.8s to 520ms.

Real-time web audit that scores Core Web Vitals, technical and on-page SEO, and accessibility.

• Scores the six field metrics that actually decide a page — LCP, CLS, INP, TTFB, FCP and TBT — beside technical SEO, on-page SEO and accessibility, in one pass rather than three separate tools.
• The output is a prioritised, commit-ready fix list keyed to the exact file and line with the metric delta each change is expected to buy, because a generic score report tells you that you have a problem and not where it is.

Outbound sales automation — contact enrichment, per-prospect sequences and warm replies routed to the CRM.

• Enriches contacts out of a Sales Navigator search, generates a sequence per prospect rather than one template with merge fields, and routes warm replies straight back into the CRM instead of leaving them in an inbox.
• Sync is bi-directional across HubSpot, Salesforce, Pipedrive and Close, with domain warmup scheduled ahead of volume to hold bounce rates under 2% — the number that decides whether the domain keeps delivering at all.
