Amos Godwin owns it and moved it onto new scanner hardware. ## Now - **Konga Group**, senior software engineer, November 2025 to now. Rebuilding the shopping app in Flutter, keeping the native Android app and warehouse scanner app shipping, and building the billing side of Konga's retail ads platform. - **Emelar Republik**, founder and CTO, February 2024 to now. Five products shipped across fintech, femtech and AI. ## Konga in numbers - $50M+ in sales through the platform - 200k+ shoppers on the mobile app - 2 app stores, one codebase ## Work at Konga ### Konga Mobile Flutter, 2026. I’m rebuilding the app that carries Konga’s mobile revenue, and its 200,000+ shoppers, in Flutter. Stack: Flutter, Kotlin, Swift ### Konga for Android Kotlin, maintained, 2025. A rebuild is no excuse to stop selling. While the Flutter development progressed, I kept the native app shipping: fixed guest checkout to cut friction at the till, richer product filters, a global flash-sale banner, improved analytics tracking, and a faster product listing amongst other squashed bugs. Stack: Kotlin, Java, XML ### Konga Warehouse App Warehouse scanner app, 2015–26. Every order the app sells has to physically move. This is the app warehouse staff use to scan each waybill from origin, through incoming and outgoing, to last mile. It dates from the Eclipse era (an 11-year-old codebase) and still runs on handheld scanners across Konga’s warehouses. I own it: I keep it stable and recently extended it to new scanner hardware, so logistics never waits on software. Stack: Java, Android support libs ### Konga Ads Platform Retail ads platform, 2026. Konga’s retail media network: sponsored placements across search and listings, sold on a CPC model. I built the billing and spend layer, click-to-impression attribution and deduplication, ad slot allocation, and spend control across concurrent campaigns. Stack: NestJS, MySQL, BullMQ, ElasticSearch, Redis ## Emelar Republik products ### Constitution.ng Legal AI assistant, 2026. The Nigerian Constitution in plain words, in five languages. Every answer cites the exact section, with the verbatim text a tap away, so it informs instead of guessing. Designed and built by me, retrieval pipeline to interface. Stack: FastAPI, React, RAG, LLM retrieval ### MOmsi Femtech app, 2025. Mothers log feeds, naps and nappies and share the day with their partner. I started as the founding engineer and went on to lead a team of four engineers across different stacks: I set the standards, unblocked the team, and took it from first commit to store release. Stack: Flutter, PostgreSQL, TypeScript ### KiaKia FX Cross-border payments, 2024. Send money across borders, swap currencies and pay online with a virtual card. I ran the front-end migration onto a modern stack without interrupting live payments, and cut API latency with request caching. Stack: Flutter ### BedtimeAI Voice cloning, 2024. A parent records a short sample and the app tells bedtime stories in their voice. I built all of it, mobile app to voice pipeline, with OpenAI Whisper inside. Stack: Flutter, TypeScript, Whisper ### Asian Proshots AI headshots, 2023. Studio-grade corporate headshots from a handful of selfies, using fine-tuned open Stable Diffusion models. I led the system design, built the mobile app and ran the model training pipeline. Stack: Stable Diffusion, Replicate, Flutter ## Earlier roles - Showwcase, USA (2021–24): Senior engineer.
