About Emmanuel
I build practical, scalable systems that connect software engineering with real operational impact.
I'm Emmanuel Oyekan, a London-based Senior Full-Stack Developer with 6+ years of experience building production-grade web applications, cloud-native systems and workflow automation platforms.
My work spans fintech platforms, backend scalability, AWS serverless architecture, payment workflows, automation tooling and data-driven systems.
Professional story
From engineering foundations to full-stack product delivery.
My background started in engineering, where I developed a strong interest in systems, problem-solving and process optimisation. That foundation has shaped how I approach software: I do not just think about writing code, I think about how the system behaves, how people use it, where it may fail, and how it can scale reliably.
Over the years, I have worked across financial technology, operational platforms, automation systems, cloud infrastructure and data-heavy backend workflows. At Fluna, I helped build and scale financial platforms supporting lending, invoice discounting, cashflow forecasting, FX risk mitigation, reconciliation and multi-currency financial operations.
I have also worked on high-volume backend workflows involving millions of records, using event-driven architecture, queues, batching and cloud services to improve reliability and processing performance.
What I do
What I bring to technical teams.
I work comfortably across the full product lifecycle, from planning and architecture to implementation, deployment, optimisation and ongoing maintenance.
Full-stack product development
I build responsive, reliable and maintainable applications using React, TypeScript, Node.js and modern frontend/backend architecture.
Cloud-native backend systems
I design backend services and workflows using AWS serverless services, queues, event-driven architecture, CI/CD pipelines and scalable database patterns.
Fintech and payment workflows
I have experience building systems around lending, reconciliation, payment tracking, FX workflows, high-value transactions and financial operations.
Automation and AI-enabled workflows
I use n8n, LLM integrations and workflow automation to remove repetitive manual tasks, connect business processes and improve efficiency.
Data and background processing
I have worked on batch jobs, migration workflows and background processing systems involving large operational datasets.
Product and stakeholder alignment
I bridge technical and non-technical teams by explaining complex systems clearly and aligning implementation with business priorities.
Leadership and mentorship
I care about building people, not just platforms.
4
engineering interns mentored
Beyond hands-on development, I have supported and mentored engineering interns and junior developers through code reviews, technical guidance, delivery support and day-to-day coaching.
I have mentored four engineering interns, helping them grow in confidence, improve their coding practices and progress into junior and mid-level engineering roles.
For me, technical leadership is not only about owning architecture. It is also about raising standards, improving team delivery and helping other developers become more effective.
Energy and sustainability
A software engineer with an energy systems perspective.
Alongside my software engineering experience, I hold an MSc in Sustainable Energy Engineering with Distinction from the University of Nottingham. My academic work focused on sustainable biomass valorisation and optimised biofuel production, combining experimental analysis, process optimisation and data interpretation.
This background gives me a useful perspective for energy-tech, climate-tech, infrastructure and other technically complex domains. It helps me think in systems, understand operational constraints and approach software problems with an engineering mindset.
How I work
How I approach engineering work.
I like to understand the problem before jumping into the solution. I care about the user journey, the business process, the data model, the failure points and the long-term maintainability of the system.
My approach is practical and delivery-focused. I value clear communication, simple architecture where possible, strong typing, reliable APIs, clean data flows, useful documentation and steady iteration.
Whether I am building a new product, refactoring a complex workflow, improving performance or automating a manual process, my goal is the same: create software that is reliable, understandable and genuinely useful.

Positioning
The kind of work I am drawn to.
I am most interested in engineering work that combines product thinking with technical depth. That includes fintech platforms, workflow automation, internal tools, AI-enabled operations, cloud-native systems, infrastructure products, energy-tech and data-driven applications.
I enjoy teams that care about quality, ownership, communication and measurable impact. I am at my best when I can help turn complex operational problems into clear, reliable and scalable software.
Let's build something useful.
I am open to senior full-stack, frontend, backend, cloud, platform and automation-focused engineering opportunities, particularly roles involving fintech, AI-enabled workflows, operational platforms, infrastructure, energy-tech and scalable product systems.
