URL: https://saheedoladele.com Job title: Senior Software Engineer Employer: Scalable Capital (https://de.scalable.capital/en) Teaches at: University of Europe for Applied Sciences (https://www.ue-germany.com/) Languages: English, German ## Contact - LinkedIn: https://www.linkedin.com/in/saheed-oladele - GitHub: https://github.com/suretrust Preferred channel: LinkedIn. ## Currently - Building: Payments investigations tooling at Scalable Capital: designing & shipping frontend, data layer, and backend services behind transactional workflows. - Teaching: Frontend programming at the University of Europe for Applied Sciences. - Writing: On Agent Experience (AX), and how interfaces change when the primary user is a model. - Exploring: What it takes to design and build for agents, and what that asks of the systems behind them. ## Tools of the trade React, TypeScript, JavaScript, Next.js, GraphQL, PostgreSQL, Node.js, Kotlin, Spring Boot, Ruby, Ruby on Rails, AWS, Terraform, Docker. ## About I'm Saheed, a senior software engineer. I work across the full stack at Scalable Capital (https://de.scalable.capital/en): front to back, infrastructure included, wherever a problem leads. I also spend a lot of time on the quieter cross-service work: design systems, performance budgets, and developer experience. I didn't start here. My first degree was in electrical engineering, communications track: signals, modulation, the physical layer of how information moves. Software was the side door I kept walking through until it became the whole house. The transition taught me that the hard part of engineering is rarely the syntax. It's reasoning clearly under constraints you didn't choose. That instinct transferred more cleanly than any specific skill. At Scalable Capital I work across the entire stack. React and TypeScript on the front, with Node, Kotlin, and Spring Boot on the services behind them. GraphQL and PostgreSQL sit in the middle, and the infrastructure underneath is AWS shaped by Terraform and deployed through Docker. A lot of the job is the quieter work where systems meet: keeping several polyglot services coherent across the JavaScript and JVM worlds at once. Teaching keeps me honest. You can't hand-wave a concept to a room of people who will use it on Monday. It's also where a lot of my writing starts. I've published technical writing on freeCodeCamp and LeadDev, including a few pieces that still rank on Google years later. I also write on my own blog. Most recently I wrote for Babbel about Agent Experience (AX) after ViteConf 2025: what changes about how we build interfaces when the primary user reading and acting on them is a model, not a person. > The web spent thirty years optimising for human attention. The next stretch is about being legible to something that doesn't have any. ## Writing ### AI Emergence at ViteConf 2025: UX, DX, now AX Publisher: Babbel Published: Nov 2025 Reading time: ~7 min Topics: AX, Frontend URL: https://www.babbel.com/en/magazine/ai-emergence-at-viteconf-2025-ux-dx-now-ax Notes from ViteConf 2025 in Amsterdam. The experience layer is shifting from UX to DX to AX, Agent Experience. LLM-based agents are becoming first-class consumers of our software, and we can choose to design for them on purpose. ### 7 Steps to Navigate Onboarding as a Software Engineer Publisher: LeadDev Published: Nov 2024 Reading time: ~9 min Topics: Career URL: https://leaddev.com/hiring/7-steps-to-navigate-onboarding-as-a-software-engineer A practical, seven-step guide to joining a new engineering team.

Neighbours pool orders to unlock wholesale pricing and split delivery on staples. Chowpool sits between informal Nigerian sourcing networks and the people they feed. Buyers post what they need or join an open pool; verified sellers fulfil at farm-gate prices once a pool fills. Money is held in Paystack escrow and only released when the buyer confirms collection with a PIN, so trust isn't a leap of faith on either side. My role: I'm the founder and the only engineer. I write the product, design the interface, run the infrastructure on Hetzner behind Caddy, and handle the operational side: seller verification, ID checks, and the unglamorous customer-support work that decides whether early users come back. ### UE Frontend Course Portal Role: Lecturer · Designer · Engineer Year: 2026 Stack: Next.js, TypeScript, MDX, Netlify URL: https://ue-frontend-2026.netlify.app/ The course portal for Frontend Programming at the University of Europe for Applied Sciences. Sixteen Saturday sessions across four units, with slides, starter code, and locked-by-default instructor notes. A single-page portal that holds the whole semester in one view. Students see every Saturday's slides and starter code, track which units they've completed, and skim ahead without losing their place. Instructor notes stay locked behind a separate access flow so I can post teaching notes alongside the public material without overwhelming students. My role: I designed and built the portal alongside teaching the course. The interesting work was less the code and more the editorial call: deciding what each session needed to show before the Saturday it ran, and what could safely wait until afterwards. ## Credentials B.Tech, Electrical Engineering (Communications). ## Open to Speaking invitations, consulting, select freelance work, and principal-engineering conversations. LinkedIn is the fastest way to reach me. --- Generated from https://saheedoladele.com. See https://saheedoladele.com/llms.txt for the short index.
