    Hi! I'm James, a Harvard Computer Science graduate, an ex-Googler, and CTO-level fullstack software engineer. I have 21 years of work experience, and can meet in-person if you’re in or near silicon valley. I believe that brilliance is good; reliability is better; and most important are integrity and compassion.. I help awesome people doing amazing things in the world; and I will deliver you delightful tech and tech leadership, on time, on budget, with full transparency and candor. I provide the following services: - Fractional CTO: I will work with you to clarify your visionary goals into an actionable technical roadmap; help you secure funding if necessary; and then run the technical operation start to finish. - Web and native app development: From napkin-sketch ideation to 7+ figure production, I will deliver intuitive, elegant digital experiences to your customers, from top-rated games and 3D virtual worlds to FDA compliant medical software, on the web and on devices. - Solving “unsolvable” tech problems. Examples of real projects I was engaged for: building a low power “hurricane proof” weather camera (Weather Channel); assisting with the development of the Semantic Reactor (a Google/Alphabet internal project); building a physical neural network entirely out of glass. - Technical project management: I will ensure your project runs on time and on budget, with incremental milestones and mitigated risks, using the best of Agile and PM tooling. I can manage teams large and small. - Productionalizing Research. Give me the research paper or the patent, I’ll make it real and scalable. - Consulting, with lawyers and attorneys, as a software engineering resource, for instance with respect to contracts and other legal matters (like Privacy Policies or GDPR/CCPA concerns). - Modernization of old technology: I will migrate and modernize your legacy application using the industry’s latest best practices. I have experience with performance tuning, scalability, devops, security hardening, penetration testing, and much more. - Teaching and coaching: I teach middle and high schoolers competitive coding. I enjoy tapping into every student’s life story and motivations. I also advise entrepreneurs and can act as a sounding board for personal and professional goals. - Solutions Architect: I provide comparative analysis of modern cloud technologies and explanations of how to use them for different scenarios.

    Hi, I'm Colin (colinsygiel.com) I am a big advocate of users, design, words, and piecing it all together to create unforgettable user experiences. 𝐌𝐲 𝐩𝐚𝐬𝐬𝐢𝐨𝐧 𝐢𝐬 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐬𝐭𝐚𝐫𝐭𝐮𝐩𝐬 𝐭𝐨 𝐡𝐞𝐥𝐩 𝐜𝐫𝐞𝐚𝐭𝐞 𝐮𝐧𝐢𝐪𝐮𝐞, 𝐞𝐧𝐠𝐚𝐠𝐢𝐧𝐠 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐬 𝐭𝐡𝐚𝐭 𝐠𝐞𝐭 𝐟𝐮𝐧𝐝𝐞𝐝 - whether that's at the seed level, series A, or beyond. As a UI/UX designer, I know that the user experience is key to success. That's why I take a user-centered approach to design, starting with research and testing to ensure that every aspect of the product is optimized for the user experience. My goal is to create a seamless and intuitive experience that keeps users coming back for more. I specialize in working with startups and have experience across a wide range of industries. I understand the unique challenges that startups face and I'm always up for a new challenge. Whether you're looking to build a brand-new product from scratch or improve an existing one, I can help you create a design that resonates with your target audience. 𝐖𝐡𝐲 𝐜𝐡𝐨𝐨𝐬𝐞 𝐦𝐞 𝐚𝐬 𝐲𝐨𝐮𝐫 𝐝𝐞𝐬𝐢𝐠𝐧𝐞𝐫? ✔ 𝐈'𝐦 𝐨𝐛𝐬𝐞𝐬𝐬𝐞𝐝 𝐰𝐢𝐭𝐡 𝐭𝐡𝐞 𝐮𝐬𝐞𝐫 𝐞𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞. I believe that design should always be user-centered, and that every design decision should be based on the needs of the end-user. ✔ 𝐈'𝐦 𝐚 𝐩𝐫𝐨𝐛𝐥𝐞𝐦-𝐬𝐨𝐥𝐯𝐞𝐫. I thrive on challenges and love nothing more than finding creative solutions to complex design problems. ✔ 𝐈'𝐦 𝐚 𝐜𝐨𝐥𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐨𝐫. I believe that the best design comes from working closely with my clients to understand their needs and goals, and incorporating their feedback into the final product. ✔ 𝐈'𝐦 𝐚 𝐦𝐢𝐧𝐢𝐦𝐚𝐥𝐢𝐬𝐭. I believe that less is often more when it comes to design, and I strive to create designs that are both simple and impactful. When I'm not designing, you can find me exploring the great outdoors, surfing, and learning how to up my game in the kitchen.

    I've worked in many industries building software that spans everything from eCommerce to scientific battery testing. I rarely find a problem I can't solve and when I do I know where to go for help. I believe in people first and strive to make working with others a positive experience with clear communication and honest feedback. Business goals are top of mind when you're in a for profit industry but that's not the only thing I've been a part of or want to be a part of in the future. Art and social good is key to our futures and I've endeavored to include those in my life and work wherever possible. A lot of my family are artists so I get it, we're not all working off a todo list with exact schematics of what we want. Give me a call if you've got something you need done that involves the internet, or code in general.

    Hi my names Nestor Vega and i'm a Software Engineer. The languages and frameworks I know are Python, PostgreSQL, AWS, MongoDB, NoSQL, React.JS, Redux, JavaScript (ES6), Ruby, Ruby on Rails, SQL, Express.Js, Node.Js, jQuery, TDD, Git, which I learned after having graduated from a full-stack software engineering coding bootcamp, with those languages at hand I was able to make a Facebook clone in under a weeks time creating user authentication and having error handling with ruby and I used ruby on rails as my backend and Javascript/React as my frontend. I was able to manage a variety of components and change its state, with Full CRUD features for posts, comments, likes, friending, and users profile pages. My second biggest project was creating a game using Canvas API (Gravity Guy). With this project I learned how to make a sprite, and an algorithm that makes the sprite appear as if it’s moving. I made an algorithm that made my animation keep rendering itself, and made a button to be able to stop its loop. This was also the first time I used music in a project, which made it way more fun and exciting. We have a main menu section which gives our Canvas a “hidden” class but once we click on the “Play” button the Canvas appears and the menu’s class becomes hidden while the Canvas removes the class 'hidden' from itself. I also did a group project using a MERN framework where my main focus was on the backend and integrated AWS in order to have our images render.
