Re
:
Reference
for
Avery
Chen
—
Senior
Product
Engineer
I
am
writing
to
provide
a
wholehearted
recommendation
for
Avery
Chen
,
who
served
on
my
team
at
Halcyon
Data
from
March
2022
until
June
2025.
During
that
time
,
Avery
reported
directly
to
me
as
a
Senior
Product
Engineer
on
the
Platform
Infrastructure
group
.
I
have
managed
engineering
teams
for
over
a
decade
,
and
Avery
stands
out
as
one
of
the
most
capable
,
reliable
,
and
thoughtful
individual
contributors
I
have
had
the
privilege
to
work
with
.
Beyond
raw
technical
output
,
Avery
is
an
exceptional
cross
-
functional
partner
.
They
regularly
translated
complex
distributed
-
systems
constraints
into
language
that
product
managers
and
customer
success
leads
could
act
on
.
When
we
launched
our
multi
-
region
failover
initiative
in
late
2023,
Avery
wrote
the
runbooks
,
led
the
dry
-
run
exercises
,
and
presented
the
rollout
plan
to
a
skeptical
executive
audience
.
The
migration
completed
three
weeks
ahead
of
schedule
with
zero
customer
-
facing
downtime
.
I
recommended
Avery
for
promotion
to
Staff
Engineer
in
our
most
recent
cycle
,
a
decision
the
leadership
team
supported
unanimously
.
They
are
leaving
Halcyon
only
because
their
partner
relocated
to
Boston
,
and
they
are
eager
to
join
a
mission
-
driven
company
like
Meridian
.
I
have
no
hesitation
predicting
that
Avery
will
become
a
cornerstone
of
whichever
engineering
team
is
fortunate
enough
to
hire
them
.
Please
feel
free
to
contact
me
if
you
would
like
to
discuss
Avery
’
s
contributions
in
more
detail
.
