Career Match
I am a technology consultant from Hong Kong. I have been working together designing, building and operating technology platforms and businesses across the globe. My core offerings are the pillars of the end-to-end services I am bringing to the market to support digital transformation.
I bring capabilities to build technology platforms that create new and exciting digital experiences.
My approach to software engineering extends beyond development to cover all the skills required to build large scale platforms. I use the right tools for every job choosing from a large set of technologies, applications, and methodologies.
I help you adopt Continuous Delivery and Cloud Computing to enable your business to adapt quickly to the changing needs and demands of their customers. I’ve worked with leading cloud providers including Amazon Ib Services, Google Cloud Platform, and Microsoft Azure to deliver a trusted, vendor-agnostic advisory and engineering service.
I help you deal with the challenges associated with connecting technology platforms in today’s complex and ever-changing environment. I do this by integrating your enterprise and cloud-based systems and leveraging the volume, variety, and velocity of data available to gain insights to better serve your customers.
My design practice takes a multidisciplinary approach to create experiences that champion the needs of real people, the requirements of the businesses that cater to their needs, and the constraints of the technologies employed to enable the business. It’s more than making things look good – it’s creating things that work.

布里斯班篇 - 六個你非去不可的原因
到布里斯班旅遊是一件賞心樂事。不但可以認識新朋友，欣賞迷人景緻，呼吸新鮮空氣… 還有物價和旅行成本都較悉尼和墨爾本相對便宜，特別適合我們這些貧窮的背包客。 我去過布里斯班兩次，合共生㓉了一年半。我認為沒有地方比布里斯班更適合旅遊。每當我認識一些背包客朋友，我都會推薦他們去布里斯班。世界著名的旅遊指南「孤獨星球」介紹布里斯班為澳大利亞最酷，最時尚的城市，是最有希望的明日之星。所以你千萬不能錯過這個地方！在我看來，布里斯班絕對值得一去，至少一生人一次，原因是甘的： 為什麼你應該馬上出發去布里斯班的六個原因 01 | 你會遇到友善的人 俗語有云「出外靠朋友」，當我翻看臉書的時候，突然發現我在布里斯班認識的朋友已經比香港的朋友還要多。當地人自然流露的熱情，親切的態度，使你有天涯若比鄰的感覺。此外，你還會遇到很多來自世界各地的好朋友。無論你走到哪裡，你都會碰上一個友好的微笑和真誠的問侯，所以不要害羞！ 02 | 天堂般的海灘和沙島 感覺就如置身在天堂一般，這樣的形容一點也沒有誇張，世界上大概沒有比這裡更好的海灘。黃金海岸的衝浪者天堂距離城市只有一個小時左右的車程，我不敢說這是最好的沙灘，
