“I was a DBA at Safra National Bank of New York while Edwin was building and supporting the applications that sat on top of our databases. That means we worked together constantly, on schema changes, on query performance, on incidents, and on the kind of late-night issues that only show up in production.
Edwin is one of the few application engineers I have worked with who really understands the database side. His SQL was clean, his data models made sense, and he asked before doing things that would hurt the server. When performance issues came up he would dig in with me instead of tossing it over the wall, and we usually fixed the root cause rather than papering over it.
He is also easy to work with, direct, patient, and willing to explain his thinking. Any team that has Edwin on it is lucky to have him.”

“Edwin and I worked together at Safra National Bank across a wide range of the bank’s systems, from client statements to compliance to middle office. Each of those areas has its own rules and its own consequences when something is wrong, and Edwin handled all of them with the same care.
He moves comfortably across the front end, services, and SQL Server, and he picks the simpler solution over the clever one. When things broke in production he was calm, methodical, and fast.
He is also someone you want on the team, a good listener, a patient mentor, and respectful with everyone from operations to senior engineers. Edwin is one of the few colleagues I would work with again without hesitation.”

“Edwin and I worked together at Safra National Bank of New York, where he was one of the core engineers behind the broker trading platform. The system touched every part of the bank, stocks, futures, options, and the integrations that tied trading into client services, credit, operations, and the middle office. That kind of footprint only works when the person building it understands the business, not just the code.
What set Edwin apart was how seriously he took the users on the trading floor and the operations teams. He would sit with traders to understand what they actually needed, then come back with something that fit the workflow instead of fighting it. He was equally comfortable in the front end, the services, and deep in SQL Server, which meant problems got solved end to end rather than thrown over a fence.
Reliability matters in a bank, and Edwin delivered it quietly and consistently. If you are evaluating him for a senior or lead role, he is the kind of engineer you can trust with a system the business depends on.”

“I worked alongside Edwin at First Republic Bank on the CRB team, building and maintaining the internal CRM that a large part of the firm depended on.
What really stood out was how much Edwin cared about his work. He wrote code that was actually easy to read, always left clear notes on his decision-making, and was super patient when explaining tradeoffs. He wasn’t afraid to push back when something didn’t feel right, but he managed to keep our standards high without ever creating unnecessary friction. That’s a rare balance to find.
Edwin is one of the engineers I have most enjoyed working with. If you are hiring senior talent, he is the kind of engineer who raises the standard of the team he joins.”

“Edwin and I worked side by side on the CRB system at First Republic Bank across every layer of the stack: front end, back end, and the database. We tackled the hardest workflows together, debugged production issues in real time, and managed deployments where there was no room for error.
What stood out about Edwin is his range. He is genuinely comfortable everywhere in the stack and does not stop at boundaries the way most engineers do. He takes ownership of problems instead of handing them off, he is disciplined and careful with code, and he has a calm temperament that is invaluable when things go sideways in production.
If you are looking for a senior engineer who can anchor a team across the full stack, who will show up for the hard work, and who will raise the quality bar for everyone around him, Edwin is that person.”
