⭐⭐⭐⭐⭐ – Oluwasegun is one of the most talented developers I’ve ever worked with. He took my rough idea and transformed it into a fully functional Bubble web app that not only looks polished but also performs flawlessly. I’ve hired developers before, but this was the first time a project was delivered on schedule, within budget, and exactly as I imagined --- (Evelyn White) If you’ve ever dealt with slow developers, overly complex solutions, or projects that never seem to reach completion, you’re not alone. Many business owners come to me frustrated after wasting weeks, or even months, trying to understand Bubble io, hiring the wrong Bubble developer, or struggling to bring their SaaS or MVP idea to life. The reality is, most people don’t need complicated code; they need a fast, dependable way to launch a Bubble app, Bubble website, or Bubble mobile app that works properly from day one. 🔥🔥🔥 That’s where I step in. I help startups, entrepreneurs, and established businesses turn ideas into powerful digital products using Bubble io, Adalo, Flutterflow, WeWeb, and other no-code platforms. Whether you want a Bubble io website, a custom Bubble CRM, a Bubble SaaS product, or a fully automated system connected with Make com automation, I deliver the strategy, design, and development needed to make it happen. 🔥🔥🔥 Here’s how I work I begin by understanding your goals, your users, and the specific results you want to achieve.

Clients leave with professional, fully functional Bubble apps, Bubble io websites, and Bubble web apps that save time, cut costs, and scale as their business grows. From SaaS platforms and marketplaces to internal dashboards and customer-facing applications, I’ve helped many businesses launch successfully and grow with confidence. I don’t just build projects, I collaborate with you. I’ve worked with founders launching their first product, agencies looking, or dependable Bubble io developers, and companies aiming to automate workflows with Make com. I also handle Adalo apps, Flutterflow mobile apps, and complex integrations, always focused on delivering a robust, scalable product ready for real-world use. Clients trust me because I blend technical expertise with creative thinking. As a Bubble io expert, I know how to push Bubble io, Adalo, and Flutterflow beyond their limits.

$700K+ delivered on Upwork across 145 projects with a 100% Job Success Score. I architect and ship production AI systems, Voice AI agents handling live calls under 2-second latency, computer vision platforms processing 8M+ daily events, and full-stack products running in production for years. What I build: 𝗩𝗼𝗶𝗰𝗲 𝗔𝗜 & 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗴𝗲𝗻𝘁𝘀 Real-time voice pipelines combining speech-to-text, LLM reasoning, and natural voice synthesis. I built SloanConnect, an AI telephony platform that automates insurance verification calls end-to-end, navigates IVR systems, holds dynamic conversations with representatives, and scales to hundreds of concurrent calls. Sub-2-second response time, encrypted compliance handling, production-stable. 𝗖𝗼𝗺𝗽𝘂𝘁𝗲𝗿 𝗩𝗶𝘀𝗶𝗼𝗻 𝗮𝘁 𝗦𝗰𝗮𝗹𝗲 Lead AI Engineer on two production CV platforms: Adlytic - privacy-safe in-store retail analytics with GDPR-compliant pipelines, heatmaps, and POS integration, and SportsEye - real-time soccer analytics from broadcast feeds with 96% accuracy across player tracking, field mapping, and tactical metrics with zero on-field hardware. 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Hybrid recommendation engines on PySpark processing 8M+ daily impressions. NLP and sentiment systems wired into live dashboards. Healthcare process automation with HIPAA-aligned data handling. Models built to live in real environments, not notebooks. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗟𝗟𝗠 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 (𝗖𝗹𝗮𝘂𝗱𝗲, 𝗢𝗽𝗲𝗻𝗔𝗜, 𝗺𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗲𝗹) End-to-end AI agents shipped to production: a Shopify + Amazon SP-API customer service agent with order lookup, refunds, returnless-refund policies, Slack/Email approval gates, and Klaviyo sync. Multi-step LLM pipelines with tool use, RAG, function calling, and human-in-the-loop checkpoints. I design these as systems, not single prompts, and I'm comfortable across Claude, OpenAI, and open-weight models depending on what fits the workload. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks. If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.
