Hi, I'm Leander

My name is Leander Costa, a Software Engineer and entrepreneur with over 20 years of experience designing, building and maintaining web products and digital platforms for startups, agencies and technology-driven companies. Based in Liverpool, United Kingdom, I have worked with clients and teams across four continents, delivering solutions across a wide range of industries and business environments.

Throughout my career, I have contributed to projects across both the private and public sectors, ranging from internal business systems and operational platforms to customer-facing applications and large-scale web solutions. My core technical expertise includes Vue.js, Nuxt.js, JavaScript, PHP and WordPress, supported by extensive experience in software architecture, technical leadership and product development. I also frequently work as a forward-deployed engineer, embedding directly with client teams to design, build and ship solutions within real operational environments.

In recent years I have integrated AI tools into my everyday engineering workflow, using them to prototype faster, automate repetitive work and explore solutions, while applying 20+ years of experience to architecture, code review, security and quality. AI accelerates execution; I own the planning, the technical decisions, the review and the final call.

Beyond engineering, I have continuously expanded my knowledge in areas such as Agile Project Management, Digital Marketing and Microsoft technologies. This broader perspective allows me to approach projects not only from a technical standpoint, but also with a clear understanding of business goals, user needs and product strategy.

I am particularly passionate about transforming complex requirements into simple, reliable and intuitive digital experiences. Combining a strong technical background with a pragmatic and client-focused approach, I help businesses turn ideas into scalable products that solve real problems, improve processes and create meaningful value for their users.
