Dosely

Precision dosing for peptides & supplements.

A dosing companion that turns error-prone protocols into a guided system: reconstitution math, vial inventory with AI label scanning, cycle planning, cost-per-dose, and a 70-compound research library with half-life decay curves. 100% SwiftUI, offline-first, cache-first repositories over Supabase, RevenueCat subscriptions.

  • Singleton-free repository architecture — chosen after production pain, not defaults.
  • Cache-first loading: every screen renders instantly, no empty-state flash.
  • Camera vial scanning through a vision model auto-fills inventory.

ModernSims

Marketing theory, made playable.

A production SaaS where student teams run virtual companies through competitive, multi-round market simulations. Six custom economic engines encode real marketing science — SERVQUAL service quality, compounding brand trust, psychographic segmentation, Porter and Ansoff strategy — each one deterministic, snapshot-tested, and calibrated against backtest harnesses that caught real balance exploits.

  • Deterministic seeded engines — instructor re-runs are byte-identical.
  • Supabase row-level security throughout, code-driven Stripe checkout, university SSO.
  • AI-assisted grading with a bounded adjustment layer and instructor override.

Pingr

Never miss a drop.

Real-time TCG restock and card-drop alerts across 23 retailers: a ping the second stock lands, a drop calendar for what's coming, and a direct link to buy. Latency is the whole product. Alerts ride Supabase Realtime while the app is open and switch to push delivery the moment it isn't.

  • Entitlements enforced server-side — RLS plus Realtime channel auth; the client is never trusted.
  • Category-agnostic schema: retailers and product lines are data, not code.
  • RevenueCat webhooks are the single source of truth for subscription state.

uMaps

Find what the world left behind.

AllTrails for urban exploration: a map-first community app for finding, rating, and logging abandoned buildings, drains, bunkers, and ruins. Over 200,000 locations, a field-trust reputation system, and a PostGIS privacy model where the public map shows a fuzzed area and the exact coordinates are earned.

  • Exact coordinates never leave the server unearned: one RPC, gated by reputation, a spent key, or Pro.
  • Keys are minted by contributing approved spots with photos. They are earned, never sold.
  • Pro is server-side truth: RevenueCat webhook → entitlements table → row-level security.

Stepsy

Walk more. Scroll less.

Stepsy locks your most distracting apps until you hit a daily step goal — screen time you earn by walking. Built on Apple's hardest frameworks: Family Controls and Screen Time for shielding, DeviceActivity for scheduling, HealthKit background delivery for steps — across four app extensions, with a Live Activity and lock-screen widgets.

  • Four extensions: shield UI, shield actions, activity monitor, widgets.
  • A tier engine converts steps into unlocks — Social at 60%, Entertainment at 100%.
  • Offline-first core loop; Supabase only for friends and leaderboards.

In the pipeline

Dashfit

In development

Sweat Arcade: prop up your iPhone, step back, and play a 3-lane runner with your body. Vision body-pose tracking turns steps, jumps, and squats into lane changes, jumps, and slides. Runs are 3–5 minutes, and every frame is processed on-device: no video is ever recorded or uploaded.

Agent infrastructure

Tools that build the tools.

Everything above ships faster because of this layer — infrastructure that gives AI agents eyes on the screen, hands on the repo, and memory that persists.

github.com/Sherif-Aboulnasr
~/tools/beam

Beam

Point at any element on a localhost app, type a prompt, and a context-loaded Claude Code session opens in iTerm2 — already cd'd into the right repo. Zero config: the bridge maps the dev-server port to its process's working directory.

MV3 extension · Node bridge · CSRF-hardened

~/tools/codex-flow

codex-flow

A workflow engine that fans orchestration scripts out over CLI coding agents: concurrency caps, schema-validated structured output, a JSONL journal, and content-addressed resume — unchanged agents replay instantly, for free.

Zero-dep Node ESM · git-worktree isolation

~/tools/screen-capture-mcp

Screen-capture MCP

Eyes for agents. A draggable overlay locks a region of the screen; the MCP server captures it on demand during UI work — before, during, and after every change. The frame itself is click-through, so the app stays usable.

MCP · macOS screencapture · Tkinter overlay

~/memory

Agent memory

Persistent agent memory over linked knowledge graphs: infinite-depth taxonomy, automated regrouping, and a two-layer recall architecture — so context survives across sessions instead of dying with the window.

Python · knowledge graphs · two-layer recall

~/tools/image-handoffs

Image handoffs

AI image batches specified as self-executing Markdown docs. Background agents generate them unattended; full-quality originals stay out of git and repos ship only compressed copies.

Bash · pngquant · agent fan-out

~/tools/voicetotext

VoiceToText

Fully offline push-to-talk dictation for macOS: hold a hotkey, speak, release — transcribed locally and pasted into whatever has focus. One readable file, about 150 lines. No cloud, no accounts.

Python · Whisper.cpp · no cloud

Data & research

Rigor where it counts.

Warehouses, pipelines, and published research — the analytical layer under the products.

Cross-product warehouse

A three-layer Medallion warehouse on Microsoft Fabric consolidating user, revenue, and usage data from the products' Postgres backends — automated quality checks and a Power BI dashboard of portfolio-wide KPIs.

Microsoft Fabric · Power BI · ETL

NLP emotion analysis

Graduate research at FGCU: a Python pipeline classifying 600+ research abstracts across 8 emotion categories over three years, with upstream cleaning that turns inconsistent raw inputs into analysis-ready datasets.

Python · NRC Emotion Lexicon

Gamification in finance

Co-authored research on gamification in finance; designed a 53-item survey instrument distributed to 200+ respondents.

Research design · survey methodology

Embedded motor control

Led a four-person FSU senior capstone: PID motor control on MSP432 with a real-time data-acquisition pipeline sampling RPM, torque, and current.

About

One owner, no handoffs.

I like owning the whole thing: the domain math, the schema, the app, the paywall, the marketing site, and the pipeline that ships it. I co-founded EFN Group (consumer iOS) and founded SKA Digital (education SaaS), and I'm finishing an MS in Data Analytics & AI while running both.

Most of my work ships with an agent fleet behind it — tooling I built so AI can see the screen, open the right repo, remember context, and do real work.

End to end

Domain math to App Store listing — design, build, ship, and support, one owner.

Honest numbers

The map says "area approximate" when it is. Store numbers come from the store. Every stat on this page is real.

Agents at work

Every product ships faster because the tooling around it compounds.

Let's build something
worth paying for.

Open to interesting problems and ambitious teams.
