Full stack application developer

I specialize in full stack development with an emphasis on front end, mobile-first, development.

I use technology to enrich people.

As a serial entrepreneur over the past 2 decades, I have a powerful understanding of business, technology, and people. I have scaled code to reach millions, both from a development and server perspective. My strength lives in my ability to communicate abstract concepts and support others in thinking through complex thought processes. I understand various components of tech, from DNS, to APIs, to servers, to development, to frontend/backend, and I can help someone think through their project and learn what's best. I can also share in a way that is sustainable, where someone is learning on their own. I want you to succeed without me. I also have consulted around business strategy and the psychology of entrepreneurship to optimize success. If you're not satisfied with any time we spend together, no charge. I value impact.

Polyglot developer with an obsession for modularity

I'm a self taught developer, and ever since my first job, given enough time at a workplace I've always become the guy who people go to when they're stuck, and I've enjoyed doing the same on various online communities. I've always found those interactions very rewarding, I find it much easier to apply myself in a focused way to helping other people solve their problems. I really believe in the "teach a man to fish" cliche. If you are a student or need help working on open source, I offer a 50% rate reduction. Note that I will not solve exercises/assignments for you, I am only willing to help you to solve them yourself. Finally, I suggest you check out this great write up by Adam Goldman, another mentor on this site, which has some great tips on how better utilize this service

Geek and Entrepreneur

I'm a geek and an entrepreneur that takes pride in solving tasks elegantly within set limitations. I have had my own share of achievements and challenges with my own businesses and projects in my 15+ years as a developer. I love working with others and sharing and expanding my knowledge, which is why I'm excited to share my expertise as a mentor, colleague or consultant on your project. /**  * Technologies I work with but not limited to.  * @return a well-equipped toolbox  */ ⦾ PHP (all versions), expert level (I write PSR-2 style) ⦾ JavaScript in multiple flavors (ES6, TypeScript, CoffeeScript, etc), expert level ⦾ In varying degrees: Go, Python, Java, Elm, Elixir. I can switch between languages and language styles, and explicitly make use of design patterns ⦾ Frameworks that I use but am not limited to: Laravel; Vue.js, Angular 1+2, and Knockout.js. I quickly adapt to a new framework as I am able to quickly grasp the key concepts and I usually go directly to reading the code. ⦾ Databases and servers locally and in the cloud. I've done a lot of DevOps with AWS, Digital Ocean, etc. Tools: Ansible, Terraform, Consul, MySQL, PostgreSQL, MongoDB, etc. ⦾ I predominantly use Linux-based environments and I am an avid Vim user. I contribute to the open-source community (publish and make PRs) and in general, I'm visible on developer communities on Slack, Gitter, Stack Overflow, etc. I mastered in dynamic and open narratives in multi-player/agent games—a subject I still find use for in other work in terms of first order logic, automatons, and the formalization of information knowledge. I've worked remotely for over 8 years now and I’m well aware of the challenges and advantages of not being in the same office or time zone as that of my clients. The key points are clarity of communication and that the distance forces you to explicitly think through what your goals and requirements are. /**  * Why you should work with me.  * @return high-quality delivery  */ ⦾ I write elegant and efficient code. I believe in concise and readable code over documentation. ⦾ I take pride in delivering solid work and I naturally develop a sense of ownership. Thus, when your project succeeds, it will be a success for me as well. ⦾ I am honest about expectations. Software estimates are hard. Several smaller deliveries are better than a monstrous rollout that might never take place due to lack of funds or lost opportunity. ⦾ I am currently based in Manila, Philippines (GMT +8) but I can easily adapt my schedule to yours and come up with a suitable working arrangement with you as my client. /**  * Other Projects and Interests  * @return diversity  */ Within the past five years, I have started several businesses and projects: Places, a successful vegetarian restaurant and hub for travelers and locals in Kathmandu, Nepal; Four Red Doors, a Scandinavian-style apartment hotel for long-term guests and visitors to Kathmandu; Tiny Carrier (work-in-progress), a crowd-sourced travel and transport startup; and Helter Shelter, an earthquake relief platform focusing on providing temporary shelter for the victims of the 2015 Nepal earthquakes. At the moment I’m working on a social network for dogs written in Elm—largely inspired by my pet dachshund Loki and his online Instagram friends and fans.

I write, nurture and love clean, testable architectures. Language doesn't matter. I eat two technology stacks and a Linux meal a day.

I write, nurture and love clean, testable architectures. Language doesn't matter (PHP/C/Rust/Golang/Typescript/Python/Java). I eat two technology stacks and a Linux meal a day. How is that possible? After 15 years of programming, you start to not be in love with your toys anymore like a kid, and treat them as tools instead. What starts to matter after reaching a certain level is expressing ideas with code, not the code itself. It's the ideas that you share with your collegues, as well with the machine, that solve real-world problems that matter. Tools are just that, and in our area of expertise, they change over time quite rapidly. What stays relatively constant are the terminology, the algorithms, and the train of thoughts for solving a specific problem, given a specific scenario.

There are no stupid questions. Coding most of my life. I love it when the UX has computers serving people, not the other way around.

My primary motivation is to be useful, usually by getting computers to do what they're good at: the tedious stuff. When we do this as much as is reasonable to implement, we leave us humans more time to enjoy life. I got my real start in software development by proving myself doing exactly that: I took a very boring and error-prone business process, and automated most of it away, leaving a UI that even the most computer-averse users found intuitive. The direct and side benefits of this system are still felt at that business, 13 years later. Freelancer and @toptal talent; open to remote jobs. Tweet me at

iOS / Full-stack / Database developer with lots of Linux and Security knowledge

I mainly build iOS apps using Swift or Objective-C, and backend server API's. I'm strong with databases, especially relational such as PostgreSQL and can build out schema's and design performant queries. I've also done Javascript work and recently built a complex front-end client using React/redux/chai/webpack with complete test coverage. I've worked in a GNU/POSIX (Linux/Unix/C) environment for over 20 years and I'm strong in administration, scripting, kernels, security, that sort of thing.
