"It wasn't until last week that I actually consciously thought about how much the place has vastly changed," said Soetjipto, who, having visited the same areas he saw 10 years ago, now works for the United Nations.
"It's about integrating and living with disaster."
Walking around Banda Aceh, capital of Aceh province, he said, it is evident that this is the case. There are now evacuation points and escape routes in densely populated areas. "In kindergarten they learn how to make evacuation maps."
Like many in Britain, Andy Bastable saw on television the impact of the tsunami.
Three days later, the team leader of public health engineering at Oxfam was scrambling to order sanitation equipment on his bus to Heathrow airport.
As a water engineer, Bastable was responsible for co-ordinating the efforts to fix and re-establish water supplies and sanitation. Over a three-year period they began to put in place systems to solve the crisis, but they also worked closely with the Indonesian authorities to create good practices for the future.
"We were well aware that we had to leave behind us a legacy of sustainable inputs," said Bastable. The engineers also experienced problems resulting from "tectonic weirdness".
"Bore-holes water would come out hot. It had arsenic in it and high fluorides," said Bastable.
Beate Trankmann, country director of the United Nations Development Programme Indonesia, said it is "hard to believe" that Banda Aceh is the same place that it was. The buildings have been built taller, with places to seek shelter in case of another disaster. Roads have been widened so people can move through the city and get to higher ground.
Trankmann said that despite obvious challenges, the future for Indonesia was bright, with plenty of economic opportunities.
"We've seen human development slowing down after 2008, compared with the 2004 to 2008 period," she said.
"They [the province of Aceh] benefit from oil and gas resources ... also in terms of coffee and cocoa," she added, "but they [Indonesia's Government] also need to make sure they create economic and employment opportunities."
Such progress is a reality for Salawati, who lives in Merduati in Aceh.
"We are focused on improving our business and helping other families in our community," she told Reuters, referring to her work of making dried fish. She was speaking in her small house built with aid money on the spot where her old house stood before it was destroyed, taking her home, her business and two of her children.
"The memory of the tsunami still exists," Salawati said. "But for the future we want to move on so that we can continue our only son's education and help achieve his goals."
Soetjipto saw destruction that took away homes, roads and businesses, but lives have slowly been rebuilt. "What you see now in Aceh is everything being rebuilt."
