# Gabana — Product Engineer, System Thinker and AI Augmented Engineer gabana.dev | build@gabana.dev | Nairobi, Kenya ## Who I Am Gabana is a full-stack product engineer, system thinker, and AI-augmented engineer based in Nairobi, Kenya. I build complete SaaS systems — from the first conversation about a problem to a deployed product running in the real world. I specialise in operations software: the kind of system that has to match how a real business actually runs, not how software manuals say it should. I have owned, built, and shipped multi-tenant SaaS platforms and AI implementations that are live and in use today — PsTally and Stoka. ## What I Build - Multi-tenant SaaS platforms - Operations, shift management, and staff accountability systems - Retail and inventory management software - WhatsApp-integrated business reporting tools - Mobile money integrations (M-Pesa and similar) - AI implementations and integrations - Custom admin dashboards and analytics Stack: Laravel, PHP, MySQL, Next.js, React, JavaScript, Tailwind, Alpine.js ## Products ### PsTally — Gaming Lounge & eSports Center Management pstally.com | Case study: gabana.dev/work/pstally "Your lounge should work for you." PsTally is a specialised management software platform designed specifically for gaming lounges and eSports centers. It is particularly prominent in the Kenyan market, where it helps lounge owners transition from manual record-keeping — notebooks, mental tallies, end-of-shift arguments — to a digital, automated system. The platform focuses on solving the most common operational headaches for lounge owners: tracking session times, managing staff shifts, and preventing revenue leakage. Consoles supported: PS5, PS4, Xbox, PC. What it does: Session Management — Automated timers for every console with locked start and end timestamps. No one can argue about how long a customer played because the system has the record. The record exists. The argument doesn't. Shift Reconciliation — Tracks every shilling from the start to the end of a staff shift. At close, the system compares expected cash against actual cash in the till. Everyone sees the same number before anyone goes home. Debt Tracking — A digital ledger for outstanding balances. Tracks who owes money, how much, and for how long, with automated alerts for overdue debts. Every shilling owed is tracked to the person who owes it. WhatsApp Integration — Sends automated shift summaries and revenue reports directly to the owner's WhatsApp. No calls needed. See how your lounge performed without being there. Tournament Mode — Tools for hosting local tournaments: bracket generation, live scoring, and registration management. Built for lounges that run weekly competitions and community events. Live results from one lounge (7 weeks running): 882 sessions tracked, Ksh 96,000 in revenue recorded, close variance of Ksh 0–50 per shift. Pricing: monthly from Ksh 500 base + Ksh 300 per console. One-time licence: Ksh 30,000. Origin: I built PsTally because I owned a gaming lounge and needed it myself. The shift disputes and cash discrepancies were costing me more time than the business was worth. I built the system, the problem went away. ### Stoka — Shop Management & POS for Kenyan Retailers stoka.co.ke | Case study: gabana.dev/work/stoka | Demo: demo.stoka.co.ke "Run your shop like you're always there." Stoka is a specialised shop management and Point of Sale (POS) platform designed specifically for Kenyan retailers. It was developed to solve the "notebook problem" — the reliance on manual, error-prone record-keeping in small businesses. Stoka is built to give shop owners freedom through clarity. It allows owners to manage their shops remotely by providing a real-time system mirror of their physical store — what's selling, who's working, how much cash is in the till, what needs restocking — without them having to be there. Particularly tailored for: boutiques, shoe shops, perfume stores, cosmetics, jewellery, hair products, and any retail business managing physical stock and staff. Live numbers: 20+ shops live within the first 3 months. Setup: 30 minutes. Live within 24 hours. First shift report the same day. Core Features: Shift Reconciliation — Automatically calculates expected cash vs. actual counted cash at the end of every shift, flagging discrepancies immediately. The owner sees the result on their phone before the staff finish counting. WhatsApp Reporting — Sends automated shift summaries — sales total, M-Pesa collected, cash reconciliation — directly to the owner's WhatsApp the moment a shift closes. No calls. No chasing. Smart Restocking — Generates a shopping list based on real sales data from the last 30 days. Colour-coded by urgency (sold out vs. running low) and filterable by supplier — so at the market, the owner sees only what that supplier carries. Send the full list to a supplier via WhatsApp in one tap. Credit Ledger — Tracks customer debts and partial payments digitally, ensuring no "pay later" transaction goes invisible. Customer name and phone required. Outstanding balances and how long each has been open visible on the dashboard. Public Shop Page — Each shop gets a professional subdomain (yourshop.stoka.co.ke) where customers can browse live stock and enquire directly via WhatsApp. Stock levels update in real time. Shareable as a link anywhere — WhatsApp status, Instagram bio, direct message. Design Philosophy: Three-Tap Sales — The staff interface is deliberately simplified: tap product, add to cart, checkout. Built for staff with no technical background. No training manual required. No Hardware Required — Browser-based. Runs on any smartphone. No laptops, no specialised POS hardware, no additional investment. Proactive Dashboard — Instead of showing raw numbers and waiting, the dashboard surfaces meaning automatically: what's selling, what's low in stock, which staff are performing, whether cash is balanced. The system answers questions before the owner thinks to ask them. Pricing: Ksh 2,000/month (30 days free, no card required) or Ksh 18,000/year (25% saving, 3 months free, one payment). Origin: A client came asking for a POS system. The deeper conversation revealed they needed something more — a system that gives shop owners presence in their business without requiring them to be there physically. Stoka is that system. Everything in it was built around that idea. ## Philosophy I begin every project by mapping the real system — the people, the states, the rules — before writing a line of code. The brief is a starting point, not a specification. Most of the time the real problem is more specific than anyone described out loud, and the right solution is narrower and more useful than what was originally asked for. That clarity is the product. The code is just how it's expressed. Good operations software matches the actual rhythm of a business: shifts and closes, trust and verification, the information an owner genuinely needs — not the report that just looks thorough. ## Availability Open to new projects.
